0.6/1kV Special Explosion Proof Cable

0.6/1kV Special Explosion Proof Cable

Product Introduction

0.6/1 kV special explosion-proof cable is composed of conductor, insulation, high strength braids explosion-proof strengtheninglayer, explosion-proof armored layer and anti-static outer sheath, According to different needs of customers, the insulation layer isdivided into inorganic mineral insulation, rubber insulation and plastic insulation and other types, Under the protection of explosion-proof reinforcement layer and explosion-proof armor, the special explosion-proof cable can withstand the destructive power of 5s kilogram of T’NT at a certain distance. At the same time, the anti-static outer sheath can effectively guide the static electricity generated by thefriction between the cable and non-insulators, and prevent the safety accidents such as fre and explosion caused by static electricity ofmilitary facilities, which perfectly solves the technical problem of easy detonation of”cable electrostatic beam”. Special explosion-proofcable also solves the security problem of explosion-proof system or unit power transmission of current defense combat facilities, such asammunition depot, hangar, military port, storage depot, military and civil airports, tunnels, military exercise bases, large electric powerchemical industry, coal mine, subway terminal and other electrical equipment and facilities. lnorganic mineral insulation explosionproof cable also has: low smoke, halogen free, fame retardant, low toxicity, fire and other combustion characteristics, and through theUK BS6387 the most demanding C, W,2 class and BS8491 fre test, while the cable has good fexibility, strong compression abilitymanufacturing length and other characteristics.

Use the feature
Explosion-proof
Under the protection of the strengthening layer, the special explosion-proof cable can withstand the destructive power of 55 kg TNT a certain distance. The anti-static outer sheath can effectively guide the static electricity generated by friction between cables and noninsulators, and prevent the safety accidents such as fre disaster and explosion of military facilities caused by static electricity.
Fire
With inorganic mineral insulation, the cable can be used normally for 180 minutes under 830’℃ fame. Therefore, it is the fireprotection system and safety requirements ofthe use of fire cable products.
Low smoke, halogen free
Non-toxic When the low smoke halogen free fame retardant polyolefins antistatic jacket is used, the cable combustion will notproduce smoke, halogen and toxic gases in case of fire.
Radiation resistant, electromagnetie interference
The resistance value of the insulating material will not change afer radiation. It is an ideal wiring cable in nuclear facilities. Atthe same time, the copper sheath of the cable forms a natural and optimal shielding layer, which can be used in computer room, powerdispatch and control room and other places that need shielding.
High mechanical strength
First of all, the special material determines the high mechanical strength, and secondly, the cable can keep the current surfaceunchanged when it is compressed by extermal force to 2/3 of the original cable diameter.

Design application selection
In the design and application, it is the same as the ordinary cable, with simple wiring, small space occupancy and more diverselaying methods. The mineral insulated freproof cable does not need to wear pipe, bridge or trough, and can be used with bracket, hanger or open application.
The cable can be laid together with other ordinary cables in the same bridge, cable trench, single-core cable is not allowed to be alone through pipe.
When the route of a certain line is long, and there are parts of the whole line that need to be insulated with mineral fire cables, and there are also parts that can be used with ordinary plastic cables, it can be converted through the conversion box. When plastic cable is available, it can he converted through the converter box.
