Abstract

The invention discloses a high-low-temperature resistant, weather-roof and flame-retardant control cable which mainly comprises a plurality of conductors, a tinned copper wire armor layer, a butyronitrile insulating layer, a chlorosulfonated polyethylene sheath layer, a steel tape armor polyolefin sheath layer, a polyvinyl chloride insulating layer and a silicon rubber insulating layer, wherein one aluminum conductor is arranged in the center of the cable; the tinned copper wire armor layer is wrapped outside the aluminum conductor; the butyronitrile insulating layer is wrapped outside the tinned copper wire armor layer; the chlorosulfonated polyethylene sheath layer is wrapped outside the butyronitrile insulating layer; and the silicon rubber insulating layer is arranged on an outermost layer. The cable has good high-low-temperature resistance, can normally operate for a long time in an environment of -110-350 DEG C, is high in oxidation resistance, and has excellent flame retardance and a good electrical insulating property.

Description

A kind of high-low temperature resistant type of resistance to marquis flame-proof control cable

Technical field

The invention belongs to field of cables, relate in particular to a kind of high-low temperature resistant type of resistance to marquis flame-proof control cable.

Background technology

The industrial and mining enterprises of China's the northern province of, winter, more than when daytime equipment operation work, ambient temperature can reach Baidu, equipment in night rear cable out of service is by the cold environment in subzero tens degree of temperature, in this special environment, need the one can be high temperature resistant, the type of resistance to marquis cable that again can be cold-resistant, to ensure the normal operation of equipment under north of china in winter adverse circumstances.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the invention provides a kind of high-low temperature resistant type of resistance to marquis flame-proof control cable.

The present invention takes following technical scheme to realize: a kind of high-low temperature resistant type of resistance to marquis flame-proof control cable, it mainly comprises many conductors, tinned copper wire armour, butyronitrile insulating barrier, chlorosulfonated polyethylene sheath layer, steel-tape armouring polyolefin jacket layer, polyvinyl chloride insulation layer and silicone rubber insulation layer, it is aluminium conductor that this cable center position is set to a conductor, outside aluminium conductor, wrap up one deck tinned copper wire armour, outside described tinned copper wire armour, wrap up one deck butyronitrile insulating barrier, outside described butyronitrile insulating barrier, wrap up one deck chlorosulfonated polyethylene sheath layer, outermost layer is silicone rubber insulation layer, between described tinned copper wire armour and butyronitrile insulating barrier, be evenly extruded with four copper conductors, between described butyronitrile insulating barrier and chlorosulfonated polyethylene sheath layer, be evenly extruded with four tinned copper conductors, between described chlorosulfonated polyethylene sheath layer and steel-tape armouring polyolefin jacket layer, be evenly extruded with four nickel conductors, between described steel-tape armouring polyolefin jacket layer and polyvinyl chloride insulation layer, be evenly extruded with four aluminium alloy conductors.

The present invention has following beneficial effect in sum: the present invention has good high-low temperature resistant, often phase normally operation in-110～350 DEG C of environment, and non-oxidizability is strong, has excellent resistance to anti-flammability and good electrical insulation properties.
