Overhead insulated conductors is a very novel overhead power distribution system. It offers increased safety and reliability, lower power consumption and ultimately system economy by reducing installation, maintenance and operating costs.

ACSR conductor technology is also maturing. ACSR conductor has high strength and good conductivity. It has been widely used at home and abroad at this stage, and has been widely praised by the industry.

Aerial cables have the main characteristics of high power supply reliability, good power supply security, convenient erection and maintenance, and reasonable economy. Its main technical parameters include weather resistance, insulation level, inner and outer semi-conductive shielding layers. Aerial cables are widely used in power transmission at home and abroad.

For low-temperature weather such as wind and snow, it is best to use overhead insulated cables with insulating layers, or to insulate the cables to prevent severe cold weather from affecting the normal operation of the cables.

The empty bundled cable is not to hang ordinary insulated cables or cross-linked insulated cables directly on the overhead tower, but to use a special cable similar to the production process of cross-linked cables. The most common overhead cables are generally single-core.

Fire-resistant cable refers to the performance that the sample is burned in the flame under the specified test conditions and can still maintain normal operation for a certain period of time. Its fundamental characteristic is that the cable can still maintain the normal operation of the line for a period of time in the event of a fire.

In the AC system, the phase-to-phase rated voltage of the conductors of the power cables must not be lower than the working line voltage of the circuit used. Low-voltage power cables should be insulated with XLPE or PVC extruded insulation.

Low-voltage power cables not only have excellent electrical properties, mechanical properties, heat aging resistance, environmental stress resistance and chemical corrosion resistance, but also have a simple structure, easy to use, not limited by the laying drop, high long-term working temperature, and high transmission capacity. Great advantages.

High-voltage cables are mainly used in traditional interconnection communications. Common cables are composed of copper wire conductors isolated by insulating materials. The entire cable is covered by a sheath of polyvinyl chloride material, so it has good insulation performance.
