Abstract
The invention discloses a multi-cable-core power cable with polyester fiber armor sheaths. The power cable is composed of aluminum conductor cable cores, an ethylene propylene rubber insulating layer, a copper strip armor polyolefin sheath layer, a nickel strip shielding layer, a nickel strip armor layer, a polyester fiber layer and a chloroprene rubber sheath layer. The number of the aluminum conductor cable cores is 52. The 52 aluminum conductor cable cores are stranded together and the ethylene propylene rubber insulating layer is wrapped on the 52 stranded aluminum conductor cable cores. The copper strip armor polyolefin sheath layer is wrapped on the ethylene propylene rubber insulating layer. The nickel strip shielding layer is wrapped on the copper strip armor polyolefin sheath layer. The nickel strip armor layer is wrapped on the nickel strip shielding layer. The polyester fiber layer is wrapped on the nickel strip armor layer. The power cable with the multiple cable cores and the multiple polyester fiber armor sheaths is widely applied to the petrochemical industry field, the electric power field and other fields, has excellent acid and alkali resistance and excellent shielding performance, and meanwhile has the advantages of being resistant to ageing and oxidation and high in tension strength.
Description
Technical field
The invention belongs to field of cables, relate in particular to a kind of many cable cores polyester fiber armouring sheath power 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 in petrochemical industry, the cable using in the fields such as electric power, the acid-proof alkaline to cable, the requirement of shielding properties aspect are all high especially, only meet the requirements, could improve in these fields the fail safe while manufacturing.
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 many cable cores polyester fiber armouring sheath power cable with the strong and good shielding properties of acid-proof alkaline.
The present invention takes following technical scheme to realize: a kind of many cable cores polyester fiber armouring sheath power cable, it is by aluminium conductor cable core, ethylene propylene rubber insulated layer, copper strips armouring polyolefin jacket layer, nickel strap screen, nickel strap armour, layer of polyester fiber and chloroprene rubber sheath layer composition, described aluminium conductor cable core is set to 52 groups, outside twisting together, wrap up 52 groups of aluminium conductor cable cores the ethylene propylene rubber insulated layer of one deck, outside described ethylene propylene rubber insulated layer, wrap up one deck copper strips armouring polyolefin jacket layer, outside described copper strips armouring polyolefin jacket layer, wrap up one deck nickel strap screen, outside described nickel strap screen, wrap up one deck nickel strap armour, outside described nickel strap armour, wrap up one deck layer of polyester fiber.
Described nickel strap armour inside is extruded with 16 groups of nickel conductor cable cores.
The present invention has following beneficial effect in sum: the fields such as the present invention is widely used in chemical petroleum, electric power, there is good acid-proof alkaline and good shielding properties, also have simultaneously ageing-resistant, the advantage that resistance to oxidation and pull resistance are strong.
