Abstract

The invention discloses a silver plated copper strip armored polyolefin and pressure resistant cable, composed of conductor cable cores, two tensile wires and six layers of external protection layers. The six layers of external protection layers comprise a silver plated copper wire shielding layer, a nonmagnetic metal armor layer, a copper plastic nickel strip composite armor layer, a polyvinyl chloride insulation layer, a copper strip armored ethylene propylene sheath layer and a silver plated copper strip armored polyolefin sheath layer which are arranged successively from the inside out. There are two groups of conductor cable cores; the two groups of conductor cable cores are extruded in the silver plated copper wire shielding layer; two groups of zinc plated annealed copper conductor cable cores and two zinc plated aluminium wire drainage wires are extruded in every group of conductor cable cores; two fixed aluminium alloy wires are extruded in the silver plated copper wire shielding layer and outside of the two groups of conductor cable wires. The cable is acid and alkali resistant and pressure resistant; the position stability of the cable cores in the cable is strong; the highest working temperature reaches 160 degrees centigrade; and the lowest layout temperature is 15 degrees centigrade below zero.

Description

A kind of silver-plated copper strips armouring polyolefin and resistance to voltage cable

Technical field

The invention belongs to field of cables, particularly relate to a kind of silver-plated copper strips armouring polyolefin and resistance to voltage 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 in the strong silver-plated copper strips armouring polyolefin of the positional stability in cable and resistance to voltage cable.

The present invention takes following technical scheme to realize: a kind of silver-plated copper strips armouring polyolefin and resistance to voltage cable, it is by conductor cable core, two tension silks and six layers of external protection composition, six layers of external protection are followed successively by silver-gilt copper wire screen from inside to outside, nonmagnetic metal armour, copper moulds nickel strap composite armor, polyvinyl chloride insulation layer, copper strips armouring second propylene restrictive coating and silver-plated copper strips armouring polyolefin 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 annealed copper conductor thread cores, two zinc-plated annealing aluminium wire drainage silks, one deck polytetrafluoroethyl-ne propylene insulating barrier and strata perfluor polyethylene layer composition, two groups of zinc-plated annealed copper conductor thread cores and two zinc-plated annealing aluminium wire drainage silks are evenly extruded in polytetrafluoroethyl-ne propylene insulating barrier inside, zinc-plated annealed copper conductor outer wrapping one deck copper strip shielding layer in described zinc-plated annealed copper conductor thread core, described zinc-plated annealing aluminium wire drainage silk outer wrapping one deck silicone rubber insulation layer, two tension silks are evenly extruded in silver-gilt copper wire screen, nonmagnetic metal armour, copper is moulded between nickel strap composite armor and polyvinyl chloride insulation layer, described silver-gilt copper wire screen is inner and extrude two fixing aluminum-alloy wires outside two groups of conductor cable cores, two both sides between two groups of conductor cable cores.

The cross-sectional diameter length of described zinc-plated annealing aluminium 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.
