Cross-linked power cable, the full name is copper core cross-linked polyethylene insulated PVC sheathed power cable. This kind of cable has a wide range of applications in the power system, mainly used to transmit electric energy. The following is a detailed analysis of cross-linked power cable:

I. Product composition

Conductor: usually use high conductivity copper core as the conductor to ensure good current transmission performance.

Insulating layer: The insulating layer is made of cross-linked polyethylene (XLPE) material. This material is treated by cross-linking process, which has excellent heat resistance, aging resistance and mechanical strength, and can effectively isolate the conductor from the external environment to prevent current leakage.

Sheath: The sheath layer is generally made of polyvinyl chloride (PVC) material, which has good weather resistance, wear resistance and chemical corrosion resistance, and can protect the cable from damage caused by the external environment.

2. Product features

Heat resistance: The crosslinked polyethylene insulation layer has excellent heat resistance and can maintain stable electrical performance in high temperature environment.

Aging resistance: due to the stable molecular structure of cross-linked polyethylene, it is not easy to age, so the copper core cross-linked polyethylene insulated PVC sheathed power cable has a long service life.

High mechanical strength: The cross-linked polyethylene insulation layer has high mechanical strength, which can withstand certain mechanical stress and protect the cable from damage during laying and use.

Superior electrical performance: The copper core cross-linked polyethylene insulated PVC sheathed power cable has stable electrical performance, high insulation resistance and low dielectric loss, which is suitable for various power transmission occasions.

Iii. Scope of application

Copper core cross-linked polyethylene insulated PVC sheathed power cables are widely used in urban power grids, industrial and mining enterprises, transportation facilities, energy development, construction projects, and other fields as the main or branch lines for power transmission. Especially in medium and low voltage power transmission systems, copper core cross-linked polyethylene insulated PVC sheathed power cables are favored due to their excellent performance.

Iv. Laying method

The installation methods for power cables with copper core, cross-linked polyethylene insulation, and PVC sheathing are diverse, including direct burial, conduit installation, cable tray installation, and trench installation. The specific method should be chosen based on project requirements, environmental conditions, and cable specifications. During installation, it is important to protect the cables from mechanical damage and moisture erosion to ensure their electrical performance and service life.

V. Matters needing attention

When purchasing and using copper core cross-linked polyethylene insulated PVC sheathed power cables, products produced by regular manufacturers should be selected to ensure that the quality of cables meets national standards and engineering requirements.

Before laying the cable, the cable should be inspected for appearance and electrical performance to ensure that the cable is undamaged and has good electrical performance.

During the laying process, the relevant specifications and standards should be followed to ensure that the parameters such as cable bending radius and laying depth meet the requirements.

During the use of cables, the electrical performance and appearance of cables should be checked regularly to find and deal with potential problems in time.

To sum up, copper core cross-linked polyethylene insulated PVC sheathed power cable is a kind of excellent performance and wide application range of power transmission equipment. In practical application, the cable specification and laying method should be reasonably selected, and the maintenance and management of the cable should be strengthened to ensure the safety and reliability of power transmission.
