The heat-generating cable is made of a cable structure, and uses electricity as an energy source, and uses an alloy resistance wire to conduct electricity and heat to achieve the effect of heating or heat preservation.
The copper core has high mechanical strength and can withstand large mechanical tension, which brings great convenience to construction and creates conditions for mechanized construction.
In the power line, the proportion of cables is gradually increasing. The power system of the power cable is a cable product for transmitting and distributing high-power electric energy in the trunk line.
According to the statistics of the public security fire department, the accident rate of the whole building is about 40% due to the failure of the electric wire and cable itself
After the cable enters the water, under the action of the electric field, the water tree aging phenomenon will occur, and finally the cable breakdown will occur.
It is suggested that the Shanghai copper 1809 contract can be low and low at 49,500-50,200 yuan/ton. Damage is 450 yuan / ton each.copper cable will lower in cost then .
In the winter, many construction workers will find that wire and cable products with good quality often have some hard lines and damaged insulation skin.
