Background

The electric wires and cables for power transmission and information transmission are widely used in industrialized and information-based society, and a large amount of electric wires and cables are produced and put into use every year in China. As most of the preparation materials of the cable sheath layer and the insulating layer are organic polymers and carry a large amount of fire load, once the mutually communicated cables are in fire due to electric faults such as electric arcs, short circuits and the like, the released toxic gas and heat can seriously harm the health of people, and the cable fire also has extremely strong spreading property. With the improvement of fire protection requirements, flame-retardant cables are required to be used in important places (such as nuclear power stations), a typical PVC (polyvinyl chloride) resistant cable releases a large amount of gas when being heated, the whole PVC resistant cable shows violent expansion and foaming effects, and a porous carbon layer formed by expansion has the functions of heat insulation and oxygen isolation, so that the ignition process becomes more complicated.

Meanwhile, the sheath and the insulating layer are gradually corroded due to the fact that the environment is humid or air is oxidized when the cable material is used, the cable cores are exposed in the air or the multiple cable cores are mutually contacted to generate electric arcs so as to cause short circuit, a fire disaster is easily caused when large-area power failure occurs, the cable needs to be protected, and an anti-corrosion cable is needed to solve the problem.
