Application of Insulation Materials for New Energy Vehicle Cables

Cable is an important power equipment that can transmit signals. There are many kinds of commonly used insulating materials, generally polyvinyl chloride (PVC), polyethylene (PE), cross-linked polyethylene (XLPE), halogen-free low-smoke polyolefin, fluoroplastics, silicone rubber, nitrile, ethylene propylene rubber, nylon, etc. Among them, polyethylene is divided into: low density (LDPE), medium density (HDPE), high density (HDPE), linear low density (LLDPE). Selecting cables produced by good materials can promote the development and improvement of wire and cable manufacturing processes, and improve the product quality and production efficiency of cables.

Among them, the materials commonly used by OMG' cable manufacturers are produced by XLPE. XLPE uses high-density polyethylene as the main raw material. Through the action of high-energy rays or chemical initiators, the linear macromolecular structure is transformed into a spatial network structure. Cross-linking can significantly improve the performance of polyethylene materials. Compared with polyethylene, cross-linked polyethylene has excellent environmental stress cracking resistance, heat resistance and thermal strength, heat aging resistance, creep deformation resistance, higher tear resistance, notch cracking resistance, electrical insulation, flame retardancy, barrier properties, gasoline resistance and aromatics resistance, overcoming the sensitivity of ordinary polyethylene to fillers. In addition, the following materials are often added to the insulation layer and sheath of the cable to make the cable have special uses.
