Detailed Description

As electric vehicles are the norm today, I believe everyone will know something about electric vehicles and the cables inside the car. Cable products are like blood vessels in the power system, and the cable outer sheath is the outermost layer of the cable, just like the outer skin of the human body. . The following is a brief introduction to the role of the cable outer sheath, the relevant regulations of the cable outer sheath, and the common materials of the cable outer sheath.

The function of the cable outer sheath is to enhance the insulation performance and protect the cable from mechanical damage; there are many common materials in daily life. Sheath materials can be divided into metal materials and non-metal materials; metal materials include copper, aluminum, and lead sheaths; non-metal materials include polyvinyl chloride, polyethylene, polypropylene, nylon, fluoroplastics, and silicone rubber , chloroprene rubber, chlorosulfonated polyethylene, nitrile rubber, low-smoke halogen-free polyolefin, polyurethane, TPE, etc.

Regarding the regulations and standards for cable outer protection, they are processed strictly in accordance with them. The first characteristic of the quality of the product is the appearance quality of the product. No matter which product or semi-finished product it is, during production, All must pay attention to appearance quality and implement strict control and inspection.

The sheath is the appearance of the cable. Its appearance is required to be smooth and round, with uniform luster, no deviation from the core (not exceeding the specified deviation), no mechanical damage, flattening, and no visible debris, bubbles, blisters, obvious particles, bamboo Nodular shape, twist shape, etc. In addition to meeting the above quality requirements, the thickness of the sheath also has a certain impact on the quality of the cable.

As the outer sheath standard, the thickness of the sheath must be calculated and controlled according to the standard. The thickness of different products, whether single core or multi-core, is based on the standard. The difference between sheathing materials and insulation materials lies in the differences in conditions such as environment and temperature. The following serves as a brief introduction to the role of the differences. The main function of the sheath material is to protect the cable. Used to select sheath materials based on external conditions, temperature, humidity, chemical environment and special requirements.

The main function of insulating materials is to provide protection for conductor insulation. Non-insulating materials and temperature levels are selected according to the conductor’s heating conditions, service life and special requirements.
