Fire caused by improper decoration construction and decoration is one of the main causes of home fires, of which 30% of the fires are caused by old residential electrical lines or improper construction. Therefore, electrical line fire prevention in the process of home decoration can not be ignored.
The cable sheath is the outermost layer of the cable, acting as the most important barrier in the cable to maintain the safety of the internal structure, maintaining the cable from mechanical damage during and after the installation.
Power cable is one of the essential materials for the transmission of power energy, and is widely used in economic production. Once the cable fails, it will not only threaten the safe and stable operation of the power grid, but also cause economic losses to the enterprise, and it will cause a chain reaction of damage. Today, Xiaobian will take you to understand about safe and qualified cables, what tests need to be done before leaving the factory?
The insulation layer, like the protective layer, shielding layer, sheath layer and conductor core, is a necessary basic component of wire and cable. It ensures that the current or electromagnetic wave or light wave transmitted by the conductor wire core only travels along the wire and does not flow outside, and also ensures the safety of external objects and people. In today's wire and cable insulation materials, plastic and rubber two categories of surface polymer materials have dominated the m
Aluminum alloy cable is a new type of material power cable using advanced technology such as special compaction process and annealing treatment. Aluminum alloy cable makes up for the shortcomings of the previous pure aluminum cable, improves the electrical conductivity, bending performance, creep resistance and corrosion resistance of the cable, and can ensure that the cable maintains continuous performance and stability when overloaded and overheated for a long time.
