Abstract

The invention discloses a special shielding polyethylene sheathed cable. The special shielding polyethylene sheathed cable is composed of conductor cable cores and five outer protective layers; the five outer protective layers are a silver-plated copper wire shielding layer, a zinc-plated nickel wire shielding layer, a butyronitrile insulation layer, an aluminium strip armour layer and a silver-plated nickel strip armour polyethylene sheathed layer sequentially from inside to outside; the two sets of conductor cable cores are extruded in the silver-plated copper wire shielding layer; two sets of zinc-plated annealing nickel conductor wire cores and two zinc-plated copper wire drainage wires are extruded in each set of conductor cable cores; and two fixed aluminium wires are extruded in the silver-plated copper wire shielding layer and outside the two sets of conductor cable cores. The cable disclosed by the invention is acid and alkali resistant and pressure resistant; the position stability of the cable cores in the cable is high; the highest working temperature is up to 160 DEG C; and the lowest laying temperature is minus 15 DEG C.

Description

A kind of shielding pe sheath special cable

Technical field

The invention belongs to field of cables, particularly relate to a kind of shielding pe sheath special cable.

Background technology

Electric wire is widely used in every field, relates to people's lives, industrial production every field, at present, and the cable used on industrial equipment especially, quality requirement is high especially, has now a kind of cable, withstand voltage, acid and alkali-resistance, cable core position stability, and allow working temperature high.

Summary of the invention

In order to increase the practicality of prior art, the object of this invention is to provide a kind of withstand voltage, acid and alkali-resistance, cable core is at the strong shielding pe sheath special cable of the positional stability in cable.

The present invention takes following technical scheme to realize: a kind of shielding pe sheath special cable, it is made up of conductor cable core and five layers of external protection, five layers of external protection are followed successively by silver-gilt copper wire screen from inside to outside, zinc-plated nickel wire screen, butyronitrile insulating barrier, aluminium strip armour and silver-plated nickel strap armouring pe sheath layer, described conductor cable core is provided with two groups, two groups of conductor cable cores are extruded in silver-gilt copper wire screen inside, often organizing conductor cable core is by two groups of zinc-plated annealing nickel conductor thread cores, two zinc-plated copper wire drainage silks, one deck polytetrafluoroethyl-ne propylene insulating barrier and strata perfluor polyethylene layer composition, two groups of zinc-plated annealing nickel conductor thread cores and two zinc-plated copper wire drainage silks are evenly extruded in polytetrafluoroethyl-ne propylene insulating barrier inside, zinc-plated annealing nickel conductor outer wrapping one deck copper strip shielding layer in described zinc-plated annealing nickel conductor thread core, described zinc-plated copper wire drainage silk outer wrapping one deck silicone rubber insulation layer, described silver-gilt copper wire screen is inner and extrude two fixing aluminium wires outside two groups of conductor cable cores, two both sides between two groups of conductor cable cores, a copper wire drainage silk is extruded between described silver-gilt copper wire screen and zinc-plated nickel wire screen, an aluminium wire drainage silk is extruded between described zinc-plated nickel wire screen and butyronitrile insulating barrier, a nickel wire drainage silk is extruded between described butyronitrile insulating barrier and aluminium strip armour.

The cross-sectional diameter length of described zinc-plated copper wire drainage silk is 0.3 ㎜.

The present invention has following beneficial effect in sum: this kind of cable acid and alkali-resistance, withstand voltage, and the positional stability of cable core in cable is strong, and maximum operating temperature reaches 160 DEG C, and minimum temperature of laying is-15 DEG C.
