Abstract

The invention discloses a power control insulating shielding double-sheath cable. The power control insulating shielding double-sheath cable is composed of grounded cable cores, a butyronitrile insulating layer, a tinned copper wire shielding layer, a copper tape armor layer, a low-smoke zero-halogen polyolefin sheath layer and a chlorosulfonated polyethylene sheath layer, wherein the grounded cable cores are divided into three sets, the three sets of grounded cable cores are wrapped in the butyronitrile insulating layer, the butyronitrile insulating layer is wrapped in the tinned copper wire shielding layer, the tinned copper wire shielding layer is wrapped in the copper tape armor layer, and the copper tape armor layer is wrapped in the low-smoke zero-halogen polyolefin sheath layer. The power control insulating shielding double-sheath cable is widely applied to the fields such as the petrochemical industry and electric power, has good acid and alkali resistance and high-temperature resistance, and has the advantages of being resistant to aging and oxidization and high in tension strength.

Description

A kind of electric power control insulation shielding double sheathed cable

Technical field

The invention belongs to field of cables, relate in particular to a kind of electric power control insulation shielding double sheathed cable.

Background technology

At present, along with socioeconomic development, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as the cable using in the field such as electric power, metallurgy, acid-proof alkaline to cable, the requirement of resistance to elevated temperatures aspect are all high especially, only meet the requirements, and could improve the fail safe while manufacturing in these fields.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of electric power control insulation shielding double sheathed cable with the strong and good resistance to elevated temperatures of acid-proof alkaline.

The present invention takes following technical scheme to realize: a kind of electric power control insulation shielding double sheathed cable, it is made up of ground connection cable core, butyronitrile insulating barrier, tinned copper wire screen, copper strips armour, low-smoke halogen-free polyolefin restrictive coating and chlorosulfonated polyethylene sheath layer.Described ground connection cable core is three groups, outside three groups of ground connection cable cores, wrap up one deck butyronitrile insulating barrier, outside described butyronitrile insulating barrier, wrap up one deck tinned copper wire screen, outside described tinned copper wire screen, wrap up one deck copper strips armour, outside described copper strips armour, wrap up one deck low-smoke halogen-free polyolefin restrictive coating, described butyronitrile insulating barrier inside is extruded with three copper wire tension silks.

Described ground connection cable core is made up of aluminium conductor, semiconductive packed layer, nickel strap screen, copper conductor and silicone rubber insulation layer.

Described aluminium conductor is 5, is extruded in semiconductive packed layer inside, and described copper conductor is 8, is extruded in nickel strap screen inside.

The present invention has following beneficial effect in sum: the present invention is widely used in the field such as electric power, metallurgy, has good acid-proof alkaline and good resistance to elevated temperatures, also have simultaneously ageing-resistant, the advantage that resistance to oxidation and pull resistance are strong.
