Conductor Material: This series of cables adopt conductor materials that meet the standards. High - purity copper is usually selected as the conductor. Copper has excellent electrical conductivity, which can effectively reduce the loss during power transmission and ensure the efficiency of power transmission. High - purity copper can also reduce the resistance of the conductor itself and improve the current - carrying capacity, which is an important basis for different specifications of this series of cables to meet different current - carrying requirements. At the same time, Copper Conductors have good ductility and mechanical strength, which can withstand a certain amount of external force during the production, laying and use of the cable, are not easy to break, and ensure the service life of the cable.

Insulating Material: The cable uses insulating materials that meet the standards, and the insulating layer has good electrical resistance. This kind of insulating material usually has high insulation resistance and breakdown strength, which can effectively prevent current leakage and ensure the insulation performance of the cable. Even in the long - term use process, it can resist the action of the electric field, is not easy to undergo insulation aging and damage, thus ensuring the safety of power transmission. In addition, the insulating material also has certain temperature resistance and corrosion resistance, and can adapt to the use requirements in different environments.

Style Design: The overall structure of this series of cables is suitable for fixed laying. In appearance, the cable presents a regular circular structure, which is convenient for arrangement and fixing during laying. The outer layer of the cable usually has a sheath. The sheath material has certain mechanical strength and wear resistance, which can protect the internal conductor and insulating layer from external damage. The fixed laying design enables the cable to maintain a stable position after installation, is not easy to be pulled and moved by external forces, thus ensuring the stability of power transmission.

Conductor Manufacturing: First, the copper raw materials are screened and purified to remove impurities to ensure that the purity of copper meets the requirements. Then, the copper material is drawn into Copper Wires with the required diameter through a wire drawing process, and multiple copper wires are stranded to form a conductor. The stranding process can improve the Flexibility and mechanical strength of the conductor, and at the same time ensure the uniform conductivity of the conductor. During the stranding process, the stranding pitch and tension are strictly controlled to ensure that the structure of the conductor is tight and stable.

Insulating Layer Extrusion: The extrusion molding process is used to wrap the insulating material around the outer layer of the conductor. Before extrusion, the insulating material is pretreated to ensure that it is in a good molten state. The molten insulating material is evenly wrapped around the surface of the conductor through an extruder to form an insulating layer. During the extrusion process, the extrusion temperature, speed and pressure are accurately controlled to ensure that the thickness of the insulating layer is uniform, the surface is smooth, and it is closely combined with the conductor without defects such as bubbles and impurities. The thickness of the insulating layer is designed according to the rated voltage and use scenario of the cable to ensure that it has good electrical resistance.

Cabling Process: Multiple conductors (main conductors and auxiliary conductors) wrapped with insulating layers are cabled according to a certain structure. During the cabling process, the conductors are stranded together by a cabling machine, and appropriate filling materials are filled at the same time to make the structure of the cable more round and stable. The filling material usually has certain elasticity and insulation performance, which can buffer the effect of external forces on the conductor and prevent moisture and impurities from entering the inside of the cable.

Sheath Extrusion: The sheath is extruded on the outer layer of the cabled cable. The sheath material is also strictly selected and has good mechanical properties, corrosion resistance and weather resistance. The extrusion process is similar to that of the insulating layer, ensuring that the sheath thickness is uniform, the surface is smooth, and it is closely combined with the internal structure. The sheath can further protect the internal structure of the cable and improve the overall strength and service life of the cable.

Quality Inspection: Strict quality inspection procedures are set in all links of production. The diameter, resistance and other parameters of the conductor are inspected; the thickness, electrical resistance, insulation resistance and other properties of the insulating layer are tested; the structure, outer diameter and other aspects of the cabled cable are checked; the thickness, mechanical properties and other characteristics of the sheath are inspected. Only the cables that pass all inspections can enter the next process, and finally ensure that the Rvfv series cables leaving the factory meet the relevant standards and requirements.

Transportation Methods: Select appropriate transportation methods according to factors such as the quantity, specification and transportation distance of the cables. For a small amount of short - distance transportation, truck transportation can be adopted; for a large amount of long - distance transportation, railway transportation or long - distance road transportation can be chosen. During transportation, it is necessary to ensure that the cable packaging is firm to avoid shaking and collision during transportation.

Transportation Precautions: Transport vehicles should drive smoothly, and avoid operations such as sudden braking and sharp turns to prevent the cable reels from rolling or colliding. Cables should avoid exposure to the sun, rain and high - temperature environments during transportation to prevent the insulating materials and sheath materials from being damaged by environmental factors. For reels with cables, they should be placed upright and not placed flat or stacked to avoid deformation of the reels due to pressure or damage to the cables due to extrusion. When loading and unloading cables, special loading and unloading equipment should be used, and rough loading and unloading is strictly prohibited to prevent the cable reels from falling or colliding.

Transportation Tracking: For long - distance transportation of cables, a transportation tracking system is established to monitor the position and driving status of transport vehicles in real - time. In case of special situations such as bad weather and road congestion, corresponding measures can be taken in time to ensure that the cables can be delivered to the destination on time and safely.

Delivery Preparation: After receiving the order, warehouse managers will accurately retrieve the Rvfv series cables of the corresponding specification and quantity according to the order requirements. Re - check the packaging and marking of the cables to ensure that they are consistent with the order information and that the packaging is intact. At the same time, prepare relevant delivery documents such as delivery notes, packing lists and quality inspection reports, and the information on the documents should be accurate and clear.

Delivery Process: Hand over the prepared cables and delivery documents to the transportation department. After the transportation department checks the cables and documents and confirms that they are correct, it arranges transport vehicles and personnel for delivery. Before delivery, the transport personnel will inspect the transport vehicles to ensure that the vehicles are in good condition and suitable for transporting cables. When delivering the goods, the delivery information will be fed back to the customer in time, informing the customer of the delivery time, transportation method, estimated arrival time and other information of the cable to facilitate the customer to make receiving preparations.

Emergency Delivery Service: Provide emergency delivery services for customers with urgent needs. After receiving an emergency order, give priority to arranging links such as goods retrieval, packaging and transportation to shorten the delivery time and ensure that the cables can be delivered to the customer as soon as possible.
