Abstract
The utility model discloses an armoured tensile double-sheath cable, which is constituted of grounding cable cores, an ethylene propylene rubber insulating layer, a galvanized aluminium wire armor, a low-smoke halogen-free polyolefin sheath layer, an aluminium strip armor and a chlorosulfonated polyethylene sheath layer. Three grounding cable cores are provided. The three grounding cable cores are coated with the ethylene propylene rubber insulating layer. The outside of the ethylene propylene rubber insulating layer is coated with the galvanizing aluminium wire armor. The outside of the galvanizing aluminium filament armor is coated with the low-smoke halogen-free polyolefin sheath layer. The outside of the low smoke halogen free polyolefin sheath layer is coated with the aluminium strip armor. 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
Technical field
The utility model belongs to field of cables, relates in particular to a kind of armouring 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 armouring 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 armouring tension double sheathed cable, it is by ground connection cable core, ethylene propylene rubber insulated layer, zinc-plated aluminium wire armoured layer, low-smoke halogen-free polyolefin restrictive coating, 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 the ethylene propylene rubber insulated layer of one deck, outside described ethylene propylene rubber insulated 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 low-smoke halogen-free polyolefin restrictive coating, outside described low-smoke halogen-free polyolefin restrictive coating, wrap up one deck aluminium strip armour, described ethylene propylene rubber insulated layer inside is extruded with three group aluminum alloy conductor cable cores.
Described aluminium alloy conductor cable core inside is extruded with 19 aluminium alloy conductors.
Described ground connection cable core is made up of aluminium conductor, belting layer, nickel strap screen, nickel conductor and silicone rubber insulation layer.
