With the arrival of UHV, "new infrastructure" and "East number and West calculation", it has brought major opportunities to China's cable industry.

In the fire in our country, the fire caused by wire and cable accounted for a large proportion of the fire, the fire igniting wire and cable combustible insulation and sheathing materials led to further expansion of the fire accident, wire and cable insulation and sheathing materials burning emit toxic gas will cause casualties, and hinder the fire extinguishing personnel, fire may lead to fire equipment power lines burned down. Can not ensure the normal operation of fire electrical equipment, d

In recent years, the advantages of fire-resistant power cables have become more prominent. According to the survey, in the global power system fire accident, the proportion of power system power supply interruption caused by power cable fire has an increasing trend. Therefore, in power plants, substations, underground railways, high-rise buildings and other places with a large number of electrical equipment and dense laying of a large number of cables, it is increasingly important to use fire-re

Flame-retardant cable refers to the cable that under specified test conditions, the sample is burned, and after the test fire source is removed, the flame spreads only within a limited range, and the residual flame or residual burn can extinguish itself within a limited time.

Control cables belong to electrical equipment cables, and power cables are two of the five categories of cables. The color of the insulated core of the control cable is generally black with white characters, and the low voltage of the power cable is generally color separated.

There are many electrician master said: "To choose a good wire, is to pick the insulation layer." Do you agree? Indeed, the quality of the wire depends largely on the performance of the insulation layer, because the insulation layer plays a role in protecting the wire, such as: anti-breakdown, high temperature resistance, aging resistance, flame retardant, low dielectric coefficient and so on.
