Cross-linked polyethylene is a commonly used core insulation material for power cables. It is close to the conductor to prevent conductor leakage. The polyvinyl chloride sheath is a commonly used outer sheath for cables to protect the outermost part of the cable. The wire core inside is not enough to protect against damage. The application directions of the two materials are different. Polyethylene undergoes cross-linking treatment to obtain cross-linked polyethylene. Dipolyvinyl chloride is made by adding various materials to PVC resin. Cross-linked polyethylene on the market is based on cross-linking. Different linking methods include UV cross-linking, silane cross-linking, chemical cross-linking, and various materials. Due to different process materials, the prices are also different, ranging from 12,500 to 15,000. PVC is relatively common, and the most common ones range from 6,000 to 7,000. Advanced ones will be better. The price will also increase
