High-power cables are commonly used in factories and large facilities. These cables are used for large equipment requiring high power consumption. However, the same material can have different uses depending on the type of wire or cable. For example, radiation-cross-linked wire is widely used in Europe, the US, and Japan. Its environmentally friendly, safe, long-lasting properties, and exceptional heat, chemical, and radiation resistance have made it an essential component of home furnishings in these countries. However, as cables, they are generally used for heat-resistant building wiring, automotive wiring, aviation wiring, locomotive wiring, and wiring for motors and electrical appliances.
Overview of Radiation-Cross-Linked Power Cables
1. Radiation-cross-linked cables utilize high-energy radiation to blast hydrogen atoms from the molecular chains, creating gaps in the molecular chains. Adjacent chains then bond together to form C-C cross-links, creating a network-like macromolecular structure that forms cross-linked polyethylene.
2. After irradiation, cross-linked polyethylene (XLPE) can achieve a thermal performance of 105°C. Irradiation cross-linking is a physical cross-linking process, eliminating the presence of water. The water content in the insulation is less than 100 parts per million (PPM), resulting in high insulation purity. Consequently, irradiation-cross-linked cables possess uniquely superior electrical and mechanical properties, with a service life of up to 60 years. Furthermore, the cables are lightweight, simple in structure, and can be installed without height restrictions.

VV, VLV, VY, VLY, YJV, YJLV, YJY, and YJLY are suitable for indoor and outdoor installation. They can withstand certain traction during installation, but cannot withstand mechanical forces. Single-core cables are not permitted to be laid in magnetic conduits.
VV22, VLV22, VV23, VLV23, YJV22, YJLV22, YJV23, and YJLV23 are installed indoors, in tunnels, and in cable trenches. They can withstand a certain amount of mechanical force but not excessive tension.
VV32, VLV32, VV33, VLV33, YJV32, YJLV32, YJV33, and YJLV33 are installed indoors, in tunnels, and in cable trenches. They can withstand a certain amount of mechanical force.

In the previous article, I'd like to expand on the advantages of irradiation cross-linked wire. It possesses excellent mechanical and physical properties, including good resistance to environmental stress cracking and abrasion resistance. It can withstand concentrated mechanical stress better than PVC and PE. It is also resistant to various chemical solvents and relatively stable in corrosive media. These advantages are why it is widely used in many European and American home renovations.
