The 300/500V special explosion-proof computer cable is composed of conductor, insulation, shock-absorbing flling, ulra-high molecular weight explosion-proof material cladding, metal braid layer, explosion-proof armor layer and explosion-proof outer sheath Under the protection of shock-absorbing packing, explosion-proof wrapping, explosion-proof strengthening and explosion-proof armorthe special explosion-proof cable can withstand the shock wave pressure of about 5lvPa. At the same time, the antistatic outer sheath can effectively guide the static electricity generated by the fiction between the cable and the non-insulator, prevent the hire, explosion and other safety accidents caused by static electricity in military facilities, and perfectly solve the techmical problem that the “cable electrostatic bundle” is easy to detonate, The shock-resistant outer sheath can provide limited protection against the impact damage suchas shrapnel cuting caused by the explosion. Special explosion-proof cables also solve the cuent national defense combat readines facilities, such as oil depots, chemical storage, ammunition depots, hangars, militany ports, cavems, military and civil airports, tunnel smilitary exercise bases. large electric coal mines, subway hazardous terminals and other electrical equipment facilities Doetchenicaexplosion-proofsystem or unit power transmission secunty problems
