Abstract

The invention discloses a low-smoke zero-halogen double-layer shielding drainage cable. The low-smoke zero-halogen double-layer shielding drainage cable comprises a silvered aluminum conductor wire core, silvered nickel conductor wire cores, tinned copper conductor wire cores and six outer protective layers. The six outer protective layers include a butyronitrile insulating layer, a silvered aluminum strip shielding layer, a silvered nickel strip shielding layer, an aluminum plastic nickel strip composite membrane strip-wrapping layer, a steel strip armoring polyolefin sheath layer and a low-smoke zero-halogen polyethylene sheath layer in sequence from inside to outside. One silvered aluminum conductor wire core is arranged, and the silvered aluminum conductor wire core is located in the center of the cable; the number of the silvered nickel conductor wire cores is set to be six, and the number of the tinned copper conductor wire cores is set to be twelve. Two silvered aluminum alloy wire drainage wires are arranged between the butyronitrile insulating layer and the silvered aluminum strip shielding layer in a press wrapping mode. The low-smoke zero-halogen double-layer shielding drainage cable resists the high temperature, is good in flame-retardant effect, high in air tightness and good in shielding effect, further has good water resistance, and is especially applicable to the related fields of chemical engineering and petroleum.

Description

A kind of low smoke and zero halogen double layer screen leading cable

Technical field

The invention belongs to field of cables, particularly relate to a kind of low smoke and zero halogen double layer screen leading cable.

Background technology

At present, electric wire is widely used in every field, relate to people's lives electricity consumption, industrial production every field, so the consumption of cable is huge especially, also high to the requirement of quality, but in every field, the quality purposes of cable is required it is different, as used electric wire in the fields such as oil, chemical industry and aviation, just require that they have good shield effectiveness and good water resistance, drainage effect is good, could be durable in use, satisfy the demand.

Summary of the invention

In order to increase the practicality of prior art, the object of this invention is to provide a kind of shield effectiveness good, and there is the low smoke and zero halogen double layer screen leading cable of good water resistance.

The present invention takes following technical scheme to realize: a kind of low smoke and zero halogen double layer screen leading cable, it is by silver coated aluminum conductor thread core, silver-plated nickel conductor thread core, tinned copper conductor core and six layers of external protection composition, six layers of external protection are followed successively by butyronitrile insulating barrier from inside to outside, silver-plated aluminium strip screen, silver-plated nickel strap screen, plastic-aluminum nickel strap composite membrane belting layer, steel-tape armouring polyolefin sheath layer and low smoke and zero halogen pe sheath layer, described silver coated aluminum conductor thread core is set to one group, be positioned at cable center position, silver coated aluminum conductor thread core inside extrudes six roots of sensation silver coated aluminum conductor, described silver-plated nickel conductor thread core is set to six groups, be extruded in butyronitrile insulating barrier inner, silver-plated nickel conductor thread core inside extrudes four silver-plated nickel conductors, described tinned copper conductor core is set to 12 groups, evenly be extruded in silver-plated aluminium strip screen inner, described tinned copper conductor core inside extrudes seven tinned copper conductors, two silver coated aluminum B alloy wire drainage threads are extruded with between described butyronitrile insulating barrier and silver-plated aluminium strip screen.

Described silver coated aluminum conductor thread core, silver-plated nickel conductor thread core and tinned copper conductor core inner conductor outer wrapping one deck low-smoke halogen-free polyolefin restrictive coating.

The present invention has following beneficial effect in sum: this kind of cable is high temperature resistant, good flame retardation effect, and air-tightness is strong, and shield effectiveness is good, but also it is good to have good water resistance, is particularly suitable for relevant chemical petroleum field and uses.
