300/500V special Explosion-Proof Computer Cable

300/500V special Explosion-Proof Computer Cable

The 300/500V special explosion-proof computer cable is composed of conductor, insulation, shock-absorbing filling, ultra-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 amour ,the special explosion-proof cable can withstand the shock wave pressure of about 5MPa, 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 fire, explosion and other safety accidents caused by static electricity in military facilities, and perfectly solve the technical problem that the “cable electrostatic bundle” is easy to detonate, The shock-resistant outer sheath can provide limited protection against the impact damage such as shrapnel culting caused by the explosion. Special explosion-proof cables also solve the current national defense combat readiness facilities, such as oil depots, chemical storage, ammunition depots, hangars, military ports, caverns, military and civil airports, tunnels military exercise bases, large electric power, chemical, coal mines, subway hazardous terminals and other electrical equipment facilities explosion-proof system or unit power transmission security problems

Anti-explosionUnder
the protection of the explosion-proof layer, the special explosion-proof cable can withstand the shock wave pressure of about 5MPa. The anfi-static outer sheath can eiectively guide the static electricity generated by the fiction between the cable and the non.insulator, prevent the safety accidents such as fire and explosion caused by static electricity in military facilities, and the anti-shock wavouter sheath can effectively prevent the impact damage such as shrapnel cutting caused by the explosion.
Anti-electromagnetic interference
This product will not change the resistance value of the insulation material after radiation, which is the ideal distribution cable in nuclear facilities, At the same time, the cable wire braid forms a natural and optimal shielding layer, has good shielding performance and antistatic performance, and can be used in the computer room, power dispatching and control room and other places that need shielding.
