Power supply for small industrial equipment: Some small machine tools, small compressors and other equipment have relatively small power and limited power demand. Cables with small cross - section specifications such as 1×70mm² and 1×95mm² can meet their power supply needs. These devices are usually installed in workshops and other places, and the cables need to have a certain degree of Flexibility to facilitate wiring around the devices. Small - section cables are relatively soft, making wiring operations more convenient.

Building distribution branches: In buildings, the power load required by distribution branches in each room and area is not large. For example, lighting branches in residences and power supply branches for small household appliances can use 1×70mm² and 1×95mm² cables to ensure stable power transmission. At the same time, the internal space of the building is limited, and small - section cables occupy little space, which will not have a great impact on the building structure and appearance.

Total power distribution of large - scale buildings: The total power distribution of large - scale buildings such as large shopping malls and office buildings needs to centrally transmit more power to each distribution area. Cables with medium cross - section specifications such as 1×120mm² to 1×300mm² can undertake this task. They can effectively distribute the externally input power to each sub - distribution system in the building.

Power supply for small and medium - sized motors: Some small and medium - sized water pump motors, fan motors, etc. need stable power supply during operation. Cables with medium cross - section specifications can provide sufficient current to meet the starting and operating needs of the motors and ensure their normal operation.

Main lines of industrial parks: There are many enterprises in industrial parks, with large power consumption, and the main lines need to transmit a large amount of power. Cables with large cross - section specifications of 1×400mm² and above can meet this high - current transmission demand and ensure stable power supply for various enterprises in the park.

Substation outgoing lines: Substations are important nodes of power transmission, and outgoing lines need to transmit power from substations to various power consumption areas. Large - section cables have good conductivity and current - carrying capacity, which can efficiently and stably complete the power transmission task and ensure the normal operation of the power system.

Material

Style: The cable is of a single - core style. This style of cable has a relatively simple structure and is more flexible and convenient in wiring. Single - core cables can be laid separately according to actual needs and are suitable for a variety of complex wiring environments.

Conductor manufacturing: First, aluminum materials are smelted and cast to obtain aluminum ingots. Then, through rolling, drawing and other processes, the aluminum ingots are processed into Aluminum Conductors of the required specifications. In the processing process, it is necessary to strictly control the process parameters to ensure the dimensional accuracy and surface quality of the conductor, so as to ensure its electrical conductivity.

Insulation layer extrusion: The extrusion molding process is adopted to evenly extrude XLPE material on the surface of the aluminum conductor to form an insulation layer. In the extrusion process, it is necessary to control parameters such as extrusion temperature and speed to ensure that the insulation layer is evenly and tightly wrapped on the conductor, avoiding defects such as bubbles and impurities.

Sheath extrusion: The same extrusion molding process is used to extrude the PVC Sheath on the outside of the insulation layer. This step needs to ensure that the sheath and the insulation layer are closely combined, the thickness of the sheath is uniform, and it has good surface quality.

Cross - linking treatment: For the XLPE insulation layer, cross - linking treatment is required. Through heating and other methods, the molecular structure of XLPE undergoes a cross - linking reaction to form a three - dimensional network structure, thereby improving the temperature resistance, mechanical properties and insulation performance of the insulation layer.

Inspection and testing: After production, the cable is subject to a series of inspection and testing, including appearance inspection, dimension measurement, electrical performance testing (such as insulation resistance testing, withstand voltage testing, etc.), and mechanical performance testing (such as tensile strength testing, elongation at break testing, etc.). Only cables that pass all tests can leave the factory.

Packaging materials: Wooden reels or cable reels are used as the main packaging materials. Wooden reels and cable reels have certain strength and stability, which can support the weight of the cable and prevent the cable from being squeezed and deformed during transportation and storage. At the same time, a layer of plastic film is wrapped around the outer layer of the cable. The plastic film has the functions of moisture proof and dust proof, and protects the cable surface from pollution.

Packaging method: The cable is neatly wound on a wooden reel or cable reel. During the winding process, it is necessary to ensure that the cable is arranged closely without distortion. Then, wrap the entire cable reel tightly with plastic film, and fix the cable on the cable reel with steel strips to prevent the cable from loosening during transportation. For cables of different specifications, cable reels of appropriate sizes are selected for packaging according to their length and weight.

Transportation methods: Select appropriate transportation methods according to factors such as the number of orders and delivery locations. For short - distance transportation, road transportation can be used; For long - distance and large - batch transportation, railway transportation can be chosen. Road transportation has high flexibility and can directly deliver goods to the designated place; Railway transportation has a large transport volume and relatively low cost, which is suitable for long - distance transportation.

Transportation precautions

Delivery process

Delivery time: For cables in stock, delivery will be arranged within 1 - 3 working days after receiving and confirming the order; For cables that need to be produced, the delivery time is determined according to the production cycle. Generally, delivery will be arranged within 1 - 2 working days after production is completed. If there are special circumstances (such as raw material shortage, equipment failure, etc.), delivery may be delayed, and the customer will be informed in time.

Sample provision: If customers need, they can apply to the company for samples. The company will provide corresponding cable samples according to the specifications specified by the customer. The number of samples is generally 1 - 2 sections, and the length is determined according to the actual situation, usually 1 - 3 meters.

Sample cost: The samples themselves are free, but the transportation cost of the samples is borne by the customer. If the customer places a bulk order subsequently, the company can refund the transportation cost of the samples according to the actual situation.

Sample delivery: After receiving the customer's sample application, prepare the samples within 1 - 2 working days and send them to the customer by express. At the same time, inform the customer of the express waybill number to facilitate the customer to query the logistics information of the samples.
