8.7/15KV And Below Medium Voltage Special Explosion-Proof Cable

8.7/15KV And Below Medium Voltage Special Explosion-Proof Cable

8.7/15kV special explosion-proof cable is composed of conductor, insulation, shock-absorbing filing, ultra-high molecular weight explosion-proof material cladding, explosion-proof armor layer and explosion-proof outer sheath. According to the different needs of customers, the insulation layer is divided into rubber insulation and plastie insulation types. Under the protection of shock-absorbing packing, explosion-proof wrapping, explosion-proof strengthening and explosion-proof armor, 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 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 electrostatic bundle” is easy to detonate. Theshock-resistant outer sheath can provide limited protection against the impact damage such as shrapnel cuting caused by the explosion Special explosion-proof cables also solve the curent 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-explosion
Under the protection of the reinforced layer, the special explosion-proof cable can withstand the shock wave pressure of about 5MPa. The anti-static outer sheath can effectively 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 wave outer sheath can effectively prevent the impact damage such as shrapnel cutting caused by the explosion
Radiation and electromagnetic interference resistant
This product will not change the resistance value of the insulation material after radiation, which is the ideal distribution cable nuclear facilities. At the same time, the metal braid of the cable forms a natural and optimal shielding layer, which can be used in computer rooms, power dispatching and control rooms where shielding is required.
High mechanical strength
First of all, the special material determines the high mechanical strength, followed by the cable is fattened by external force to theoriginal cable diameter of 2/3, can still maintain the current carrying surface unchanged.
