XLPE or Cross-linked polyethylene is a thermoset insulation material. Crosslinking polymers is a process which changes the molecular structure of the polymer chains so that they are more tightly bound together and this crosslinking is done either by chemical means or physical means. Chemical crosslinking involves the addition of chemicals or initiators such as silane or peroxide to generate free radicals which form the crosslinking. Physical crosslinking involves subjecting the polymer to a high energy source such as high-energy electron or microwave radiation.Polyethylene (PE) material itself has excellent dielectric strength, high insulation resistance, and a low dissipation factor at all frequencies making it an ideal insulator, however it is limited in its temperature range. Cross-linking the PE to become XLPE increases the temperature range of the insulation whilst maintaining the electrical properties.

XLPE insulated cable is a chemical or physical method that transforms the cable-insulating polyethylene molecules from a linear molecular structure into a main network structure.That is, the thermoplastic polyethylene is converted into a thermosetting cross-linked polyethylene, thereby greatly improving it. 

At present, the insulating materials used in cable production are roughly divided into three categories: PE, PVC, and XLPE. The following describes the differences between the insulating materials PE, PVC, and XLPE used in cables.Classification of cable insulation materials and detailed explanation of their characteristics

The XLPE insulated cable, also known as the XLPE insulated wire, boasts a simple annealed twisted and solid circular copper conductor, encompassed by XLPE insulation and finished with a PVC outer sheath. We offer an extensive selection of low voltage 0.6/1kv cables ranging from one core to five cores. The cross-linked polyethylene insulated cable/wire finds extensive application in power distribution, transmission, and various network power systems. Rest assured, our XLPE insulated power cable adheres to the stringent standards of IEC 60502、IEC 60228、IEC 60332, BS, DIN and ICEA ensuring top-notch quality and reliability.

XLPE is cross-linked polyethylene that has seen significant growth in the last couple of years due to the modernization and refurbishment of electrical infrastructures in major regions such as North America and Europe.XLPE offers noteworthy advantages to insulated power cable applications compared to traditional materials due to its outstanding dielectric benefits, low smoke halogen-free, extreme temperature capabilities, and resistance to aging, chemicals, and other hazardous materials.

Physical crosslinking involves subjecting the polymer to a high energy source such as high-energy electron or microwave radiation.

Cross-linked polyethylene insulation is made by chemical or physical methods to change the polyethylene molecule from linear molecular structure to three-dimensional network structure, from thermoplastic material to thermosetting material, and to increase the working temperature from 70℃ to 90℃, which significantly improves the material performance.

There are two primary methods used to crosslink wire. Chemical (CV / Continuous Vulcanization) and Irradiation. Crosslinking helps modify specific materials, making them more reliable, longer-lasting, and increasing the material's overall resistance capabilities. With different constructions and sizes available, these reliable cables have a number of benefits that make them some of the most dependable hook-up and building wiring products on the market.

XLPE insulated cable is a cross-linked polyethylene that is insulated with a high-quality aluminum conductor armored cable. XLPE insulated cable material insulation and structure make it the best choice insulated cable in comparison with other insulated cables. ZW CABLES manufactures are by far the best XLPE insulated cable makers around the world.
