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 cable (cross-linked polyethylene)
Temperature range: XLPE is suitable for a higher operating temperature range, generally between -40°C and 90°C, and some special models can even reach 125°C.
Mechanical properties: XLPE has excellent mechanical strength and wear resistance, and is not easy to crack.
Electrical properties: XLPE has a low dielectric constant and a small capacitance effect, which is suitable for high-frequency signal transmission.
Chemical stability: XLPE has good resistance to most chemicals, including oils and solvents.
Cost: The cost of XLPE is slightly higher than PVC, but its performance advantages make it more competitive in many applications.
Environmental protection: XLPE produces less smoke and less toxicity when burned, which meets modern environmental protection standards.

XLPO cable (cross-linked polyolefin)
Temperature range: XLPO is suitable for a higher operating temperature range, generally between -60°C and 125°C, and some special models can even reach 150°C.
Mechanical properties: XLPO has excellent mechanical strength and wear resistance, and is not easy to crack.
Electrical properties: XLPO has a low dielectric constant and small capacitance effect, which is suitable for high-frequency signal transmission.
Chemical stability: XLPO has good resistance to most chemicals, including oils and solvents.
Cost: XLPO has a relatively high cost, but its high performance makes it very valuable in specific applications.
Environmental protection: XLPO produces less smoke and low toxicity when burned, which meets modern environmental protection standards.
