Abstract

The utility model discloses a tensile double-sheath cable with a wire rope. The cable is constituted of grounding cable cores, a copper strip armoured polyolefin sheath layer, a galvanized aluminium wire armoured layer, a polyvinyl chloride insulation layer, an aluminium strip armoured layer and a chlorosulfonated polyethylene sheath layer. Three grounding cable cores are provided. The three grounding cable cores are coated with the copper strip armoured polyolefin sheath layer. The copper strip armoured polyolefin sheath layer is coated with the galvanized aluminium wire armoured layer. The galvanized aluminium wire armoured layer is coated with the polyvinyl chloride insulation layer. The polyvinyl chloride insulation layer is coated with the aluminium strip armoured layer. The cable provided by the utility model is widely applied in the fields of chemical petroleum and the like, and has the advantages of excellent performances of acid and alkali resistance and high temperature resistance and meanwhile has the advantages of aging resistance, oxidation resistance and high tensile strength.

Description

A kind of band steel wire rope tension double sheathed cable

Technical field

The utility model belongs to field of cables, relates in particular to a kind of band steel wire rope tension 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 fields such as chemical petroleum, 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.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of band steel wire rope tension double sheathed cable with the strong and good resistance to elevated temperatures of acid-proof alkaline.

The utility model takes following technical scheme to realize: a kind of band steel wire rope tension double sheathed cable, it is by ground connection cable core, copper strips armouring polyolefin jacket layer, zinc-plated aluminium wire armoured layer, polyvinyl chloride insulation layer, aluminium strip armour and chlorosulfonated polyethylene sheath layer composition, described ground connection cable core is three groups, outside three groups of ground connection cable cores, wrap up one deck copper strips armouring polyolefin jacket layer, outside described copper strips armouring polyolefin jacket layer, wrap up the zinc-plated aluminium wire armoured layer of one deck, outside described zinc-plated aluminium wire armoured layer, wrap up one deck polyvinyl chloride insulation layer, outside described polyvinyl chloride insulation layer, wrap up one deck aluminium strip armour, described copper strips armouring polyolefin jacket layer inside is extruded with three group aluminum alloy conductor cable cores, between described polyvinyl chloride insulation layer and aluminium strip armour, be extruded with steel cable.

Described aluminium alloy conductor cable core inside is extruded with 19 aluminium alloy conductors.

Described ground connection cable core is made up of copper conductor, lapping layer, layer of polyester fiber, nickel conductor and silicone rubber insulation layer.

Described copper conductor is 5, is extruded in lapping layer inside, and described nickel conductor is 8, is extruded in layer of polyester fiber inside.

The utlity model has in sum following beneficial effect: the utility model is widely used in the fields such as chemical petroleum, there is 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.
