Abstract

The invention discloses a polyolefin sheath compression-resistant electric wire. The electric wire comprises conductor cable cores, two silver-plated tensile copper wires and five outer protection layers, wherein the five outer protection layers comprise a silver-plated copper wire shielding layer, a tetrafluoroethylene-hexafluoropropylene copolymer insulating layer, a chlorosulfonation ethylene propylene sheath layer, a nickel strip armoured layer and a silver-plated copper strip armoured polyolefin sheath layer from inside to outside in sequence; the electric wire is provided with two groups of the conductor cable cores; the two groups of the conductor cable cores are arranged in the interior of the silver-plated copper wire shielding layer in an extrusion manner; two groups of tin-plated aluminium conductor wire cores, two aluminium wire drainage wires and a silver-plated aluminium wire drainage wire are arranged in the interiors of each group of conductor cable cores in an extrusion manner; and six fixed aluminium alloy wires are arranged in the interior of the silver-plated copper wire shielding layer and outside the two groups of conductor cable cores in an extrusion manner. The electric wire is resistant to acid and alkali, and compression; the cable core is highly stabilized in the electric wire; and the maximum working temperature can achieve 150 DEG C, and the minimum laying temperature is minus 15 DEG C.

Description

A kind of polyolefin jacket resistance to compression electric wire

Technical field

The invention belongs to field of cables, particularly relate to a kind of polyolefin jacket resistance to compression electric wire.

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 polyolefin jacket resistance to compression electric wire of the positional stability in electric wire.

The present invention takes following technical scheme to realize: a kind of polyolefin jacket resistance to compression electric wire, it is by conductor cable core, two silver-plated tension copper wires and five layers of external protection composition, five layers of external protection are followed successively by silver-gilt copper wire screen from inside to outside, perfluoroethylene-propylene insulating barrier, chlorosulfonation second propylene restrictive coating, nickel strap armour 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 aluminium conductor cores, two aluminium wire drainage threads, the crosslinked polyetylene insulated layer of one deck, one strata perfluor polyethylene layer and a silver-plated aluminium wire drainage silk composition, two groups of zinc-plated aluminium conductor cores and two aluminium wire drainage threads are evenly extruded in crosslinked polyetylene insulated layer inside, described silver-plated aluminium wire drainage silk is extruded between crosslinked polyetylene insulated layer and poly-perfluor polyethylene layer, zinc-plated aluminium conductor outer wrapping one deck copper strip shielding layer in described zinc-plated aluminium conductor core, described aluminium wire drainage thread outer wrapping one deck silicone rubber insulation layer, described silver-gilt copper wire screen is inner and extrude the six roots of sensation outside two groups of conductor cable cores and fix aluminum-alloy wire, wherein two both sides between two groups of conductor cable cores, two silver-plated tension copper wires are evenly extruded in perfluoroethylene-propylene insulating barrier, chlorosulfonation second propylene restrictive coating, between nickel strap armour and silver-plated copper strips armouring polyolefin sheath layer.

The cross-sectional diameter length of described aluminium wire drainage thread is 0.3 ㎜.

The present invention has following beneficial effect in sum: this kind of electric wire acid and alkali-resistance, withstand voltage, and the positional stability of cable core in electric wire is strong, and maximum operating temperature reaches 150 DEG C, and minimum temperature of laying is-15 DEG C.
