Power cooper cable with isolated gross-linked polyethylene
High-voltage power cooper cables with cross-linked polyethylene insulation, manufactured using peroxide technology, are designated by the index XLPE (XL - Cross-Linked, PE - PolyEthylene). This is a premium product. Cross-linked polyethylene insulation provides excellent insulating properties, reducing signal loss and interference.
The cross-linking process of polyethylene makes it a pure structure. This structure has a high ability to resist deformation even at high temperatures.
Due to the new type of material, XLPE-insulated cable gains the following advantages:
- higher carrying capacity (permissible load currents are 15-30% higher than the limit for paper-insulated cables);
- possibility to carry out laying works at temperatures down to minus 20C;
- high thermal stability current in case of short circuit;
- low weight, smaller diameter and bending radius facilitate cable laying on complicated routes in the ground and in cable constructions;
- low specific damageability;
- large construction length (up to 2 thousand meters).
