Abstract

The utility model discloses an anti-static anti-interference cable used for instruments and meters. The cable is constituted by a polyvinyl chloride protection layer, a silvering copper wire braided shielding layer, a fluororubber insulation layer, control line cores, zero line cores, and a phase line core. The fluororubber insulation layer is disposed in the silvering copper wire braided shielding layer in a wrapped-extruded manner, and is wrapped by the polyvinyl chloride protection layer. The fluororubber insulation layer and a drainage wire are in a concentric arrangement. The outer side of the phase line core is provided with two control line cores and a plurality of zero line cores, which are in a concentric and symmetric arrangement. According to the utility model, the conductor is not easy to break. The anti-static anti-interference cable has advantages of anti-static performance, double-layer sheath protection, anti-tension performance, and anti-high voltage impact.

Description

A kind of instrument and meter antistatic Anti-interference cable

Technical field

The utility model relates to field of cables, relates in particular to a kind of instrument and meter antistatic Anti-interference cable.

Background technology

At present, the cable using in aviation ship computer and instrument, all very high to the each side quality requirement of cable, because very important of fail safe in these fields, be generally not admit of potential safety hazard to exist, in these fields, just should use so some to there are insulation property, strong interference immunity, the cable of antistatic, can better ensure and improve fail safe.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of instrument and meter antistatic Anti-interference cable.

The utility model takes following technical scheme to realize: a kind of instrument and meter antistatic Anti-interference cable, it is mainly comprised of polyvinyl chloride protective layer, silver-gilt copper wire woven shield, fluorubber insulating barrier, control core, zero line core and phase core, described silver-gilt copper wire woven shield inside is extruded with fluorubber insulating barrier, and coated outside has polyvinyl chloride protective layer; Described fluorubber insulating barrier is provided with drainage thread with one heart; Described phase core is symmetrically arranged with one heart two outward and controls core and several zero line core.

Described zero line core adopts that tinned copper wire is stranded to be formed.

Described zero line core is 6 to 12 groups.

Described phase core adopts that tinned copper wire is stranded to be formed.

The utlity model has in sum following beneficial effect: this cable has antistatic, duplex sheath protection, conductor is frangibility not, resistance to tension, high pressure resistant impact feature.
