What is overhead conductor?

September 26, 2021

Conductor is the main body of overhead line and is responsible for transmitting electric energy. Since the conductor is erected on the pole, it should often bear the effects of self weight, wind, rain, ice, snow, erosion of harmful gases and changes in air temperature. Therefore, the conductor is required not only to have good […]

Overhead cable is the main part of overhead power line. Its function is to transmit current and power. It is divided into overhead conductor and overhead insulated cable. Overhead conductors include AAC conductors, which are commonly used in distribution lines below 35KV; AAAC conductor, commonly used in distribution lines above 110kV; ACSR conductor is widely […]

With the increasing competition in the wire and cable industry, M & A integration and capital operation among large wire and cable enterprises are becoming more and more frequent. Domestic excellent wire and cable production enterprises pay more and more attention to the research on the industry market, especially the in-depth research on the change […]

We all know that wires and cables are distributed differently according to the structure of electrical conductors. Cables are divided into 1-core, 2-core, 3-core, etc. Single core cable: there is only one electrical conductor in an insulating sleeve. A wide range of main uses are home lighting equipment, power plug, central air conditioning, etc. all […]

1、 Scorch 1. Scorch phenomenon (1) The temperature is too high, or the temperature control instrument fails, causing the plastic to burn at an ultra-high temperature. (2) The glue outlet of the machine head has large smoke, strong pungent smell and crackling sound. (3) Granular scorched matter appears on the plastic surface. (4) There are […]

Power cables have long been widely used in our lives. The safety of their operation is related to our normal life and the safety of life and property. Therefore, the maintenance of cables is a vital work. The following small series will analyze what we need to know about the correct use of power cables. […]

1. External force damage According to the operation analysis in recent years, especially in places with rapid economic development, a considerable number of cable faults are caused by mechanical damage. 2.
