Cross-linked Polyethylene Cable How To Come, Xlpe Cable Is What Cable

In the needs of the work, as a company's procurement staff, often see the technical master came to say with me is still short of XLPE cable, quickly purchase a batch of XLPE cable back, the brain was stunned, this xlpe cable is what cable? Never seen, then the following I'll see what this xlpe cable is cable it!

Xlpe cable is what cable

XLPE cable is actually a cross-linked polyethylene cable, the cable is one of the most important cables in the power supply grid. xlpe power cable line operation is more important, especially the safety and reliability of the operation of cable accessories should be given high priority. Necessary and appropriate measures must be taken to prevent accidents and monitor the operation of power cable lines. test programs for XLPE cables mainly include voltage withstand tests, routine condition assessment and local discharge testing, and the main one that can be used for testing cables in field operation is local discharge testing.

How cross-linked polyethylene cables came to be

The so-called cross-linked cable is a cable that uses cross-linked type materials for insulation or sheathing. For a long time, cross-linked insulation materials have been widely used in the manufacture of medium-voltage and low-voltage cables, resulting in cross-linked polyethylene insulated cables.

In XLPE cables, the stranded conductors are first shielded in the form of semi-conductive extrusions, which provide a smooth conductor surface and prevent cavities from forming on the conductor surface when the cable is bent. The shielded conductor is insulated with an extruded XLPE compound. The insulator is further shielded with a layer of non-metallic semiconductor material to which a non-magnetic metal shield in the form of copper or aluminum tape is applied. In the case of multi-core cables, the core is laid in the cavity together with a suitable filler and wrapped with PVC tape or extruded PVC. For mechanical protection, non-magnetic aluminum wire/band/strip armor for single-core cables and wire armor for multi-core cables is provided over the inner sheath. An extruded layer of PVC/PE is used as the outer sheath, usually in the back color, to prevent the ingress of moisture.

XLPE cables are more suitable for high and ultra-high voltage environments up to 132kV. This cable can be used for relatively long cable routes in high voltage transmission where dielectric loss plays a major role. This cable is easy to handle as it is lighter in weight than any other high voltage cable. The XLPE insulation is highly resistant to moisture, so no special precautions are required when connecting and terminating. Less time is required to connect XLPE cables than any other conventional cable of similar grade. These cables can be safely used in any vibrating layout, such as bridges. These cables have better resistance to salt, chemicals, oil and corrosive ovens in the soil. There is no risk of fire with these. These cables are less prone to failures due to aging characteristics and have relatively best durability.
