Abstract

The invention discloses a heatproof fireproof special cable. The heatproof fireproof special cable mainly comprises main cable cores, a butyronitrile insulating layer, a tinned copper wire shielding layer, a silicone rubber insulating layer, a zinc-coated steel wire braiding armor layer and a neoprene sheath layer, wherein the number of the main cable cores is three, the main cable cores are arranged inside the butyronitrile insulating layer in a pressing and wrapping mode, the tinned copper wire shielding layer is wrapped on the butyronitrile insulating layer, the silicone rubber insulating layer is wrapped on the tinned copper wire shielding layer, and the zinc-coated steel wire braiding armor layer is wrapped on the silicone rubber insulating layer. The heatproof fireproof special cable has high insulation shielding performance, is high in anti-interference performance, is widely applied to the fields such as the petrochemical industry and the metallurgical manufacturing field, and further has the advantages of resisting heat, retarding the flame and being high in oxidation resistance.

Description

A kind of heat resistant fire-proof special cable

Technical field

The present invention relates to field of cables, relate in particular to a kind of heat resistant fire-proof special cable.

Background technology

At present, the cable using in petrochemical industry, metallurgical manufacture, all very high to the each side quality requirement of cable, because very important of fail safe in these fields, is generally not admit of potential safety hazard to exist, in these fields, just should use so some to there is insulation shielding performance, strong interference immunity, heat-proof combustion-resistant, the cable that non-oxidizability is strong, can better ensure and improve fail safe.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide one have fire-retardant, high temperature resistant, fire prevention, the heat resistant fire-proof special cable of corrosion resistant advantage.

The present invention takes following technical scheme to realize: a kind of heat resistant fire-proof special cable, it is mainly made up of master core, butyronitrile insulating barrier, tinned copper wire screen, silicone rubber insulation layer, zinc-coated wire braiding armour and chloroprene rubber sheath layer, described master core has three groups, be extruded in described butyronitrile insulating barrier inside, outside described butyronitrile insulating barrier, be enclosed with one deck tinned copper wire screen, outside described tinned copper wire screen, be enclosed with one deck silicone rubber insulation layer, outside described silicone rubber insulation layer, be enclosed with one deck zinc-coated wire braiding armour.

Described master core is made up of two groups of aluminium cable cores and the zinc-plated aluminium wire armoured layer that is wrapped in outside two groups of aluminium cable cores.

Described aluminium cable core is made up of aluminium conductor and the polyvinyl chloride insulation layer that is wrapped in outside aluminium conductor, and polyvinyl chloride insulation layer inside is also extruded with an aluminium wire heating wire.

Described butyronitrile insulating barrier inside is also extruded with three groups of nickel conductor thread cores.

The characteristics such as the present invention has following beneficial effect in sum: this cable has good insulation shielding performance, and strong interference immunity is widely used in the field such as petrochemical industry, metallurgical manufacture, also has heat-proof combustion-resistant simultaneously, and non-oxidizability is strong.
