The special explosion-proof cable is composed of conductor, insulation, high-strength braided explosion-proof reinforcement layer, explosion-proof armor layer and antistatic outer sheath. According to the different needs of customers, the insulation layer is divided into inorganic mineral insulation, rubber insulation and plastic insulation. Under the protection of the explosion-proof reinforced layer and explosion-proof armor, the special explosion-proof cable can withstand the destructive force of 55 kg of TNT explosives within a certain distance. At the same time, the anti-static outer sheath can effectively guide the static electricity generated by the friction between the cable and the non-insulator, prevent the fire, explosion and other safety accidents caused by static electricity in military facilities, and perfectly solve the technical problem that the "cable static bundle" is easy to detonate. The special explosion-proof cable also solves the current national defense combat readiness facilities, such as ammunition depots, hangars, military ports, caverns, military and civilian airports, tunnels, military exercise bases, large-scale power, chemical, coal, subway hazardous chemical wharf and other electrical equipment facilities Safety issues of explosion-proof system or unit power transmission. Inorganic mineral insulated explosion-proof cables also have: low-smoke, halogen-free, flame-retardant, low-toxicity, fire-proof and other combustion characteristics, and have passed the most demanding C, W, Z and BS8491 fire tests in the British BS6387.
