(I) Specification Parameters
Cable Rz1 - K (AS) has clear and rigorous settings in terms of specification parameters. Each parameter has been carefully considered to ensure that it can play a stable role in power transmission.
The rated voltage of this cable is 0.6/1Kv. This voltage level makes it suitable for low - voltage power transmission scenarios. 0.6Kv is the phase voltage of the cable, and 1Kv is the line voltage. It can meet the needs of low - voltage power transmission in general industrial, civil and other fields, and can be well adapted to power distribution equipment of the corresponding voltage level to ensure the stability of power transmission.
In terms of conductor specifications, it adopts a 1×240mm² design. "1×" indicates that the cable is a single - core structure. The single - core design has certain
Flexibility in installation and laying, especially in some scenarios with limited space or requiring separate laying. The 240mm² conductor cross - sectional area endows the cable with a strong current - carrying capacity, which can reduce power loss during long - distance power transmission and cope with the power demand of high - power electrical equipment or large - scale power distribution, such as some main lines of large shopping malls and branch transmission in industrial parks.
In terms of insulation and sheath characteristics, the cable belongs to the HFFR (halogen - free, low - smoke and flame - retardant) type. The halogen - free characteristic means that the cable material does not contain halogen elements, and will not release toxic and harmful gases such as hydrogen chloride when burning, which can reduce harm to humans and equipment; the low - smoke characteristic can reduce the smoke concentration during combustion, buying time for personnel evacuation and rescue work; the flame - retardant characteristic can slow down the burning speed of the cable, and even prevent the spread of combustion under certain conditions, improving the safety of the cable in case of fire.
In addition, the cable complies with the CPR (Construction Products Regulation) certification standard. This certification has strict requirements on the mechanical properties, fire performance, environmental protection performance of the cable, etc. Passing this certification indicates that Cable Rz1 - K (AS) meets the relevant specifications in various performances and can be safely used in construction and other related fields. At the same time, its overall outer diameter is reasonably designed, which is convenient for installation in various laying environments, whether it is pipe laying or bridge laying.
Cable Rz1 - K (AS) has a wide range of important applications in many fields relying on its unique performance advantages, and its characteristic uses are closely related to its own specification parameters and performance characteristics.
In the field of commercial buildings, it can play an important role. Large shopping malls, office buildings and other commercial places are crowded with people and have many electrical equipment, so they have extremely high requirements for the safety and stability of power transmission. Because the cable has halogen - free, low - smoke and flame - retardant characteristics, in case of fire, it can reduce the generation of toxic gases and smoke, creating favorable conditions for personnel evacuation and fire fighting and rescue. The 240mm² conductor cross - sectional area can meet the large power load of commercial places, such as the power supply of central air - conditioning, lighting systems, elevators and other equipment. The rated voltage of 0.6/1Kv can also adapt to the low - voltage power distribution system of commercial buildings.
In the industrial field, some factories with high requirements for environmental protection and safety will also choose this cable. For example, in electronic factories and food processing factories, the production environment is special, and there are strict requirements on the cleanliness and safety of the surrounding environment. The halogen - free characteristic of Cable Rz1 - K (AS) can avoid the impact on product quality and production environment caused by the release of harmful substances due to cable aging or accidental combustion. At the same time, its strong current - carrying capacity can meet the power demand of large production equipment in the factory, ensuring the continuous progress of production.
In terms of public facilities, places such as hospitals, schools and subways are also important application scenarios for this cable. There are a large number of precision medical equipment and many patients in hospitals, which have extremely high requirements for the safety and reliability of power supply. The halogen - free, low - smoke and flame - retardant characteristics can reduce the threat of fire risks to patients and medical equipment; schools are crowded with people, especially students who have weak self - protection ability. The use of this cable can provide more protection for students' evacuation in case of sudden fire; as a crowded public transport facility, the subway has a relatively closed space. In case of fire, smoke and toxic gases are extremely harmful. The low - smoke and halogen - free characteristics of Cable Rz1 - K (AS) can highlight its advantages in such scenarios and can be used in the power distribution and lighting systems of the subway.
In addition, in some residential communities with strict environmental protection requirements, the cable can also be used as a power distribution line. With the improvement of people's environmental awareness, the requirements for the safety and environmental protection of the living environment are also increasing. The use of halogen - free, low - smoke and flame - retardant cables can reduce potential safety hazards and provide a safer power environment for residents.
(III) Material and Style
In terms of material selection and style design, Cable Rz1 - K (AS) is fully combined with its performance requirements and use scenarios to ensure that the cable can operate stably in various environments.
The conductor is made of high - purity copper. High - purity copper has excellent conductivity and low resistivity, which can reduce energy loss during power transmission and improve transmission efficiency. At the same time, copper has good ductility and mechanical strength, which is easy to be processed into a 240mm² conductor, and is not easy to break during laying and use, which can ensure the stability and durability of the conductor. The surface of the conductor is specially treated to be smooth and burr - free, which can be closely combined with the insulation layer to avoid local overheating caused by poor contact.
The insulation layer and sheath are made of HFFR materials. This material does not contain halogen and is mainly composed of high - molecular polymers, flame retardants, etc. The addition of flame retardants makes the material have good flame - retardant performance, which can inhibit the combustion reaction when exposed to open fire. At the same time, the material has good aging resistance, which can resist the influence of external environmental factors such as temperature changes and humidity, and extend the service life of the cable. In addition, the HFFR material has high mechanical strength, which can effectively protect the internal conductor and prevent the conductor from being damaged due to external collision, extrusion and other external forces during laying and use.
In terms of style, the cable has a single - core structure and is round as a whole. The single - core style has strong flexibility in laying, can be bent and arranged according to actual needs, and is more easy to operate in some narrow spaces or complex laying paths. The round structure makes the cable stress evenly, which can disperse the force to the entire cross - section when subjected to external pressure, reducing the risk of local damage. Moreover, the round style is convenient for cable production and processing, winding into rolls, transportation and storage.
The outer sheath of the cable usually adopts dark colors such as black or gray. This color can not only play a certain anti - dirt role, but also resist ultraviolet radiation to a certain extent, reducing the aging of the sheath caused by direct sunlight, and is suitable for various indoor and outdoor laying environments.
(IV) Production Process
The production process of Cable Rz1 - K (AS) is rigorous and complex. Each link from raw material processing to finished product inspection has strict quality control standards to ensure that the product meets relevant requirements and certification standards.
The production of the conductor is the first step. High - purity copper rods are selected, and the copper rods are drawn into
Copper Wires of the required diameter through a wire drawing process. During the wire drawing process, the wire drawing speed and die precision are strictly controlled to ensure that the diameter of the copper wire is uniform and the surface is smooth and undamaged. Then, multiple copper wires are stranded together in a specific way to form a 240mm² single - core conductor. During stranding, the stranding pitch and tension are well controlled to make the conductor structure compact and round, improving the mechanical strength and conductivity of the conductor.
The extrusion process of the insulation layer is crucial. Special extrusion equipment is used to heat and melt the HFFR
Insulation Material, and then evenly wrap it around the outside of the conductor through a die to form an insulation layer. During the extrusion process, the temperature, pressure and extrusion speed are accurately controlled to ensure that the insulation layer has a uniform thickness, a smooth surface, is closely combined with the conductor, and has no defects such as bubbles and impurities. The thickness of the insulation layer is determined according to the rated voltage and use environment of the cable to ensure that its insulation performance meets the requirements and can effectively isolate the current leakage between the conductor and the outside.
The extrusion of the sheath is carried out after the extrusion of the insulation layer. HFFR materials are also used. The materials are melted by an extruder and then wrapped around the outside of the insulation layer. The extrusion process parameters of the sheath need to be adjusted according to the material characteristics to ensure that the sheath is closely attached to the insulation layer without delamination. The thickness of the sheath should be uniform, which can provide good mechanical protection for the cable and resist external friction, collision and other external forces. At the same time, the surface of the sheath should be flat and the marks should be clear, which is convenient for identification and laying.
During the production process, a series of treatment processes will be carried out on the cable. For example, the
Stranded Conductor is annealed to eliminate the internal stress of the conductor and improve the flexibility and stability of the conductor; the extruded insulation layer and sheath are cooled and shaped to ensure their dimensional stability and performance compliance. In addition, in order to ensure the halogen - free and low - smoke characteristics of the cable, the halogen content is strictly controlled in the selection of raw materials and the production process to avoid the introduction of halogen - containing substances.
(V) Production Process
The production process of Cable Rz1 - K (AS) covers many key links, and each link has strict operating specifications and quality inspection to ensure that the final product meets the design requirements and relevant standards.
Raw material inspection is the first link of production. For copper rods, their purity, conductivity and other indicators are tested, and only copper rods that meet the requirements can enter the next production step; for HFFR materials, their halogen content, flame - retardant performance, mechanical performance and other indicators are tested to ensure that the materials meet the characteristics of halogen - free, low - smoke and flame - retardant. At the same time, the auxiliary materials used in the production process, such as lubricants and dies, are also subject to corresponding quality testing to avoid affecting product quality due to problems with auxiliary materials.
After the conductor is stranded, the conductor performance test is carried out. It includes the DC resistance test of the conductor to ensure that its conductivity meets the standard; the appearance and size of the conductor are checked to ensure that the conductor is round and the diameter is within the specified range. If it is found that the conductor has problems such as excessive resistance and burrs on the surface, it is necessary to deal with or rework it in time.
After the insulation layer is extruded, the insulation performance test is carried out. The insulation effect of the insulation layer is tested through insulation resistance test and voltage withstand test; the thickness and eccentricity of the insulation layer are checked to ensure that the insulation layer evenly covers the conductor without insufficient thickness or excessive eccentricity. If the insulation layer has defects such as bubbles and cracks, the cable will be judged as an unqualified product and needs to be repaired or scrapped.
After the sheath is extruded, the quality of the sheath is tested. The thickness and surface quality of the sheath are tested to ensure that the sheath has a uniform thickness and no scratches, depressions and other defects on the surface; the mechanical properties of the sheath, such as tensile strength and elongation at break, are tested to verify the toughness and wear resistance of the sheath. At the same time, the flame - retardant performance and low - smoke and halogen - free performance of the sheath are tested. Through combustion tests, the burning speed, smoke concentration and harmful gas emission are observed to ensure that they meet relevant standards.
In each link of cable production, automated production equipment and precision testing instruments are used to improve production efficiency and the stability of product quality. During the production process, various process parameters such as temperature, pressure and speed are monitored in real time. Once it is found that the parameters deviate from the set range, adjustments are made in time. After production, a comprehensive performance test is carried out on the finished cable, including electrical performance, mechanical performance, flame - retardant performance, halogen - free and low - smoke performance, etc. Only cables that pass all test items can be affixed with the CPR certification mark and allowed to leave the factory.
II. General Product Information
(I) Packaging
The packaging design of Cable Rz1 - K (AS) focuses on protecting the cable from damage during storage, transportation and handling, while taking into account the convenience of packaging and the clarity of identification.
Cable reels are used for packaging, and there are two types of cable reels: wooden and metal. For cables with longer lengths, metal cable reels are usually used. Metal cable reels have high strength and strong bearing capacity, can bear the weight of heavy cables, and are not easy to be damaged after multiple uses, which are suitable for long - distance transportation and frequent handling; for cables with shorter lengths or samples, wooden cable reels can be used. Wooden cable reels have relatively low cost and light weight, which are convenient for short - distance transportation.
The cable is neatly wound on the cable reel, and appropriate tension is maintained during winding to avoid the cable being loose, twisted or rubbing against each other, preventing the insulation layer and sheath from being scratched or worn. After winding, a layer of plastic film is wrapped around the outer layer of the cable. The plastic film has good moisture - proof and dust - proof performance, which can protect the cable from damp air and dust erosion, and can reduce the impact of environmental factors on the cable especially during storage and transportation.
On the side of the cable reel, a clear product label is pasted. The label indicates the product name (Cable Rz1 - K (AS)), specification (1×240mm²), rated voltage (0.6/1Kv), length, production date, production batch number, CPR certification mark, manufacturer name and contact information, etc. The label is made of wear - resistant and waterproof materials to ensure that the information is clearly identifiable during transportation and storage, which is convenient for identification and traceability.
For exported cables, the packaging must also meet the relevant standards and requirements of the export destination. Corresponding international universal signs and text descriptions may be added to the packaging, and the strength and protective performance of the packaging are strengthened to adapt to the harsh environment of long - distance sea or air transportation.
(II) Transportation
The transportation process of Cable Rz1 - K (AS) must follow strict specifications to ensure the safety of the cable during transportation and avoid damage caused by improper transportation.
The transportation method is selected according to the transportation distance, transportation volume and customer needs. For domestic transportation, road transportation, railway transportation and other methods can be adopted. Road transportation has high flexibility and can directly transport the cable to the customer's designated location, which is suitable for medium - and short - distance transportation and small - batch transportation; railway transportation has a large carrying capacity and good stability, which is suitable for long - distance transportation and large - batch transportation. For export transportation, sea transportation or air transportation is usually adopted. Sea transportation has low cost and is suitable for large - batch and long - distance transportation; air transportation is fast and is suitable for emergency orders or small - batch transportation.
When loading the cable, special hoisting equipment such as cranes and forklifts are used. The hoisting point is selected at the central axis of the cable reel. Hoisting from the side of the cable reel or the cable itself is avoided to prevent the cable reel from being deformed or the cable from being damaged by stretching and extrusion. During the loading process, ensure that the cable reel is placed stably and fixed firmly to avoid shaking, tilting or collision during transportation. When multiple cable reels are transported at the same time, an appropriate gap is left between the cable reels, and buffer materials are used to separate them to reduce mutual friction and collision.
During transportation, protective measures must be taken. Avoid the cable being exposed to the sun or rain. If it is transported in the open air, the cable reel must be covered with waterproof canvas to prevent rainwater from entering the cable or causing the sheath to age; keep away from fire sources, heat sources and corrosive substances to prevent the cable insulation layer and sheath from being corroded or damaged by high temperature; during the driving process of the transport vehicle, drive smoothly, avoid violent operations such as sudden braking and sharp turns, and reduce the impact on the cable.
During transportation, the transport personnel must regularly check the fixing of the cable and the integrity of the packaging. If the cable reel is loose or the packaging is damaged, it must be reinforced and repaired in time. After arriving at the destination, check the appearance and packaging of the cable with the receiver, and go through the handover procedures only after confirming that there is no damage. If there are signs of cable damage, it must be recorded in time and communicated with relevant parties for handling.
