Abstract

The invention discloses a power control armor cable with multiple conductor cable cores. The power control armor cable with the multiple conductor cable cores comprises control cable cores, an ethylene propylene rubber insulating layer, a tinned copper wire armor layer, a nickel tape shielding layer, a perfluorinated ethylene-propylene copolymer insulating layer and a chloroprene rubber sheath layer, wherein the control cable cores are divided into three sets, the three sets of control cable cores are stranded together and then wrapped in the ethylene propylene rubber insulating layer, the ethylene propylene rubber insulating layer is wrapped in the tinned copper wire armor layer, the tinned copper wire armor layer is wrapped in the nickel tape shielding layer, the nickel tape shielding layer is wrapped in the perfluorinated ethylene-propylene copolymer insulating layer, and the perfluorinated ethylene-propylene copolymer insulating layer is wrapped in the chloroprene rubber sheath layer. The power control armor cable with the multiple conductor cable cores is widely applied to the fields such as the petrochemical industry and electric power, has good acid and alkali resistance and shielding performance, and has the advantages of being resistant to aging and oxidization and high in tension strength.

Description

A kind of many conductor thread cores of electric power control armoured cable

Technical field

The invention belongs to field of cables, relate in particular to a kind of many conductor thread cores of electric power control armoured 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 chemical petroleum, electric power, the requirement of the acid-proof alkaline to cable, heat-resisting shielding properties aspect is all high especially, only meets the requirements, and 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 conductor thread cores of electric power control armoured 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 conductor thread cores of electric power control armoured cable, it is by controlling cable core, ethylene propylene rubber insulated layer, tinned copper wire armour, nickel strap screen, polyfluorinated ethylene insulating barrier and chloroprene rubber sheath layer composition, described control cable core is set to three groups, outside twisting together, wrap up three groups of control cable cores the ethylene propylene rubber insulated layer of one deck, outside described ethylene propylene rubber insulated layer, wrap up one deck tinned copper wire armour, outside described tinned copper wire armour, wrap up one deck nickel strap screen, outside described nickel strap screen, wrap up one deck polyfluorinated ethylene insulating barrier, outside described polyfluorinated ethylene insulating barrier, wrap up one deck chloroprene rubber sheath layer.

Described control cable core inside is extruded with 52 groups of nickel conductor cable cores.

The present invention has following beneficial effect in sum: the present invention is widely used in the field such as chemical petroleum, electric power, has good acid-proof alkaline and good shielding properties, also have simultaneously heat-resisting, the advantage that resistance to oxidation and pull resistance are strong.
