XLPE Cable

XLPE Cable is a cable suitable for use in distribution networks and other fields. It has the advantage that PVC insulated cables can't match. 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.
It uses chemical or physical methods to transform the cable-insulating polyethylene molecules from a linear molecular structure into a main network structure, that is, a thermoplastic polyethylene is converted into a thermosetting cross-linked polyethylene, thereby greatly improving its heat resistance and The mechanical properties reduce its shrinkage, so that it does not melt after being heated, and maintains excellent electrical properties.
The XLPE insulated cable adopts a peroxide cross-linking method to change the molecular structure of the polyethylene from a linear molecular structure to a three-dimensional network structure, from a thermoplastic material to a thermosetting material, and the operating temperature is increased from 70℃ to 90℃. Improve the current carrying capacity of the cable. XLPE insulated cables have the following advantages:
1. Heat resistance: XLPE with a mesh structure has excellent heat resistance. It does 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 good insulation properties of PE and further increases the insulation resistance. The dielectric loss tangent is small and is not affected by temperature.
3. Mechanical properties: Due to the establishment of new chemical bonds between macromolecules, XLPE has improved hardness, stiffness, wear resistance and impact resistance, thus making up for the shortcomings of PE susceptible to environmental stress and cracking.
4. Chemical resistance: XLPE has strong acid and alkali resistance and oil resistance. Its combustion products are mainly water and carbon dioxide, which have less harm to the environment and meet the requirements of modern fire safety.
XLPE insulated cable is suitable for distribution network, industrial equipment or other areas requiring large-capacity electricity. It is used for fixed power transmission and distribution lines with AC 50Hz and rated voltage of 6kV~35kV. The main function is to transport electric energy.
