Features

01

Improve power supply safety

- The insulation layer can effectively prevent short circuits and grounding faults caused by direct contact between the wires and trees, buildings and other objects, reduce power outages caused by foreign objects touching, and improve the reliability of power supply.

- It can reduce the risk of electric shock for line maintenance personnel and ensure the personal safety of operation and maintenance personnel.

02

Reduce the width of the line corridor

- Since insulated wires can reduce the arcs caused by phase-to-phase short circuits and grounding faults, the phase-to-phase distance of the line and the distance between the wires and the ground and other objects can be appropriately reduced, thereby saving the floor space of the line corridor.

03

Reduce electromagnetic interference

- Compared with bare wires, the electromagnetic field distribution of overhead insulated wires is more concentrated, and the electromagnetic interference to the outside world is relatively small. It has advantages in some areas with high requirements for the electromagnetic environment (such as areas near communication lines, electronic equipment, etc.).

04

Good corrosion resistance

- The insulation layer plays a certain protective role on the wires, protecting them from direct erosion by the external environment (such as acid rain, humid air, etc.), and extending the service life of the wires.

Combo

Conductor
Conductive materials such as aluminum or aluminum alloy, copper, etc. are usually used. Aluminum and aluminum alloy conductors are low-cost and lightweight, and are widely used in medium and low voltage overhead lines; copper conductors have better conductivity and mechanical properties, but the cost is relatively high.
Insulation layer
Common insulation materials include polyethylene (PE), cross-linked polyethylene (XLPE), etc. The polyethylene insulation layer has good electrical insulation properties, chemical corrosion resistance and softness; the cross-linked polyethylene insulation layer is superior to ordinary polyethylene in terms of heat resistance, mechanical strength and environmental stress cracking resistance.
