Abstract

The utility model discloses a heatproof and fireproof special cable which is mainly composed of main cable cores, a butyronityile insulating layer, a tin-coated copper filament shielding layer, a silicone rubber insulating layer, a galvanizing steel wire braiding armor layer and a chloroprene rubber sheath layer. Three main cable cores are extruded in the butyronityile insulating layer, the tin-coated copper filament shielding layer wraps the outside of the butyronityile insulating layer, the silicone rubber insulating layer wraps the outside of the tin-coated copper filament shielding layer, and the galvanizing steel wire braiding armor layer wraps the outside of the silicone rubber insulating layer. The heatproof and fireproof special cable has good insulating and shielding performance and high interference immunity, can be widely used in fields of petroleum chemical, metallurgy manufacturing and the like, and the heatproof and fireproof special cable also has characteristics of heatproof and fireproof performance, high inoxidizability and the like.

Description

A kind of heat resistant fire-proof special cable

Technical field

The utility model relates to field of cables, relates 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.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model be to provide a kind of have fire-retardant, high temperature resistant, fire prevention, the heat resistant fire-proof special cable of corrosion resistant advantage.

The utility model takes following technical scheme to realize: a kind of heat resistant fire-proof special cable, it is mainly comprised 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 inner, 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 comprised 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 comprised 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 utlity model has in sum following beneficial effect: this cable has good insulation shielding performance, the characteristic such as strong interference immunity, is widely used in the fields such as petrochemical industry, metallurgical manufacture, also has heat-proof combustion-resistant simultaneously, and non-oxidizability is strong.
