XLPE insulated cable
XLPE insulated cable is a kind of cable suitable for distribution network and other fields, which has incomparable advantages over PVC insulated cable. The utility model has the advantages of simple structure, light weight, good heat resistance, strong load capacity, no melting, chemical corrosion resistance and high mechanical strength.
Properties of XLPE insulated cable
The crosslinked polyethylene insulated cable adopts peroxide crosslinking method to change the polyethylene molecule from linear molecular structure to three-dimensional network structure, from thermoplastic material to thermosetting material, and the working temperature is increased from 70 ℃ to 90 ℃, which significantly improves the current carrying capacity of the cable.

Low voltage cable
XLPE insulated cable has the following advantages:
1. Heat resistance: XLPE insulated power cable has excellent thermomechanical properties, excellent electrical properties and chemical corrosion resistance. At the same time, it has the advantages of simple structure, light weight and unrestricted laying. It is a new type of cable widely used in urban power grid, mines and factories. XLPE with reticular three-dimensional structure has excellent heat resistance. It will not decompose and carbonize below 300 ℃, the long-term working temperature can reach 90 ℃, and the thermal life can reach 40 years.
2. Insulation performance: XLPE maintains the original good insulation characteristics of PE, and the insulation resistance is further increased. The dielectric loss tangent is very small and is not affected by temperature.
3. Mechanical properties: due to the establishment of new chemical bonds between macromolecules, the hardness, stiffness, wear resistance and impact resistance of XLPE are improved, which makes up for the defect that PE is easy to crack under environmental stress. Crosslinked polyethylene is a kind of crosslinked polyethylene that converts linear molecular structure into three-dimensional network structure by chemical or physical means. To a great extent, it improves the thermomechanical properties of polyethylene and maintains excellent electrical properties.
4. Chemical resistance: XLPE has strong acid, alkali and oil resistance. Its combustion products are mainly water and carbon dioxide, which does little harm to the environment and meets the requirements of modern fire safety.


Application of XLPE insulated cable
XLPE insulated cable is suitable for distribution network, industrial devices or other fields requiring large capacity power consumption. It is used for fixed laying on the power transmission and distribution line with AC 50Hz and rated voltage of 6kV ~ 35kV. Its main function is to transmit electric energy.
The most important thing of polyethylene insulated cable is to protect everyone’s power safety and play the role of insulation. Therefore, pay attention to the intact packaging of the sheath when purchasing the cable. Moreover, polyethylene insulated cable has the advantages and properties that other cables do not have, which are its advantages, which makes many cables use this material now. In life, electricity is very dangerous. Choosing high-quality cables can help people use electricity normally and reduce the threat of electricity to people.
