0.7mm Insulation Thickness XLPE Insulated Power Cable
3×35 XLPE insulated cable.
XLPE insulated power cable
XlPE insulated cable stands for cross-linked polyethylene cable. It is a hydraulic pipe made of polyethylene plastic. Polyethylene was originally a general-purpose material, but its temperature resistance effect is not ideal, but after the improvement of cross-linking technology, the wire made of cross-linked polyethylene material has the characteristics of wear resistance, high temperature resistance and high current. Capacity, etc., and will not produce corrosive and toxic gas when burned, it is a truly environmentally friendly wire product. The advantages of XLPE cable include: First, the working temperature rises from 70°C to 90°C, and the temperature resistance level is obviously good; secondly, it has good insulation properties, XLPE maintains the original good insulation properties of PE, and insulation The resistance is further increased, the dielectric loss tangent value is small, and is not greatly affected by temperature. Third, the mechanical properties are enhanced, new chemical bonds are established during the cross-linking process, the hardness, stiffness, wear resistance and impact resistance of XLPE are improved, and the disadvantages of PE's vulnerability to environmental stress and cracking are made up. Finally, chemical resistance, XLPE has strong acid and alkali resistance and oil resistance. Its combustion products are mainly water and carbon dioxide, which are less harmful to the environment and are environmentally friendly products. New chemical bonds are established during the cross-linking process, which improves the hardness, stiffness, wear resistance and impact resistance of XLPE, and makes up for the shortcomings of PE's vulnerability to environmental stress and cracking.

Application
XLPE insulated cables can be used in almost all installations: ground, cable tray, indoor, power station, factory, exchange station. Because of their better thermal properties, they are especially recommended for the following occasions:
-High ambient temperature
-The cable is exposed to sunlight
-The cable is placed in the pipe of the concrete block
-Cables are grouped
-High emergency load is important
-Need high short circuit current
-High shielding layer must transmit high leakage current
