Introduction of automotive high-voltage cable materials and processing

China [CN]

The raw materials and processing process of automotive cable fittings have a crucial impact on the quality and safety of automotive cables. The following is the introduction of raw materials and processing process of auto cable accessories:

I. Raw materials

1. Conductor material: the conductor material of automotive cable accessories usually uses copper or copper alloy, because copper has good electrical and thermal conductivity, and strong corrosion resistance.

2. Insulation material: The insulation material of auto cable fittings usually uses polyvinyl chloride (PVC) or cross-linked polyethylene (XLPE), which have good insulation performance and wear resistance.

3. Sheath material: the sheath material of auto cable fittings generally uses PVC or polyamide, which have good corrosion resistance and wear resistance.

Second, processing technology

1. Conductor production: The conductor production of automotive cable accessories usually uses the stranding process, that is, multiple strands of fine copper wire stranded into a wire, in order to improve the flexibility and strength of the wire.

2. Insulation processing: The insulation processing of automotive cable accessories usually adopts the extrusion process, that is, the conductor is wrapped in the insulation material, and then the conductor and insulation material are pressed into one by the extruder.

3. Sheath processing: The sheath processing of auto cable parts usually adopts the extrusion process or injection process, that is, the insulation layer is covered in the sheath material, and then the sheath material is pressed into one by the extrusion machine or injection machine.

4. Finished product testing: The finished products of auto cable fittings need to be strictly tested, including appearance inspection, electrical performance inspection, heat resistance performance inspection, weather resistance performance inspection, etc., to ensure the quality and safety of the products.

The above is the introduction of raw materials and processing process of auto cable fittings, hope it will be helpful to you.
