Abstract

The utility model discloses a high temperature resistance cable for computers and instruments. The high temperature resistance cable is mainly composed of main cable cores, a filling layer, a chlorosulfonated polyethylene sheath layer, a silicone rubber insulating layer and a steel band armoured polyethylene sheath layer. Three groups of main cable cores are extruded in the filling layer, the chlorosulfonated polyethylene sheath layer wraps the outside of the filling layer, and the silicone rubber insulating layer wraps the outside of the chlorosulfonated polyethylene sheath layer. The high temperature resistance cable for the computers and the instruments has good insulating performance and high interference immunity, can be widely used in computers and instruments in spacecrafts, and the cable also has characteristics of flame retardation, high temperature resistance, oxidation resistance and the like.

Description

A kind of high temperature resistant computer and instrument cable

Technical field

The utility model relates to field of cables, relates in particular to a kind of high temperature resistant computer and instrument 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 is 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, fire-retardant, high temperature resistant, sludge proof cable, 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 be to provide a kind of have fire-retardant, high temperature resistant, fire prevention, the high temperature resistant computer of corrosion resistant advantage and instrument cable.

The utility model takes following technical scheme to realize: a kind of high temperature resistant computer and instrument cable, it is mainly comprised of master core, packed layer, chlorosulfonated polyethylene sheath layer, silicone rubber insulation layer and steel-tape armouring pe sheath layer, described master core has three groups, be extruded in described packed layer inner, outside described packed layer, be enclosed with one deck chlorosulfonated polyethylene sheath layer, outside described chlorosulfonated polyethylene sheath layer, be enclosed with one deck silicone rubber insulation layer.

Described master core is comprised of two group aluminum alloy cable cores and the butyronitrile insulating barrier that is wrapped in outside two group aluminum alloy cable cores.

Described aluminium alloy cable core by aluminium alloy conductor and the polyfluorinated ethylene insulating barrier, the belting layer that are wrapped in successively outside aluminium alloy conductor form.

Belting layer inside on every group aluminum alloy cable core is extruded with a drainage thread.

The utlity model has in sum following beneficial effect: this cable has good insulation property, strong interference immunity, is widely used on aviation ship computer and instrument, also has the characteristics such as fire-retardant, high temperature resistant, resistance to oxidation simultaneously.

Accompanying drawing explanation

Fig. 1 is the utility model cross-sectional structure schematic diagram;

Wherein: 1, master core; 2, packed layer; 3, chlorosulfonated polyethylene sheath layer; 4, silicone rubber insulation layer; 5, steel-tape armouring pe sheath layer; 6, drainage thread.

Embodiment

As shown in Figure 1, a kind of high temperature resistant computer and instrument cable, it is mainly comprised of master core 1, packed layer 2, chlorosulfonated polyethylene sheath layer 3, silicone rubber insulation layer 4 and steel-tape armouring pe sheath layer 5, described master core 1 has three groups, be extruded in described packed layer 2 inside, outside described packed layer 2, be enclosed with one deck chlorosulfonated polyethylene sheath layer 3, outside described chlorosulfonated polyethylene sheath layer 3, be enclosed with one deck silicone rubber insulation layer 4.

Embodiment: master core 1 is comprised of two group aluminum alloy cable cores and the butyronitrile insulating barrier that is wrapped in outside two group aluminum alloy cable cores.

Aluminium alloy cable core by aluminium alloy conductor and the polyfluorinated ethylene insulating barrier, the belting layer that are wrapped in successively outside aluminium alloy conductor form.

Belting layer inside on every group aluminum alloy cable core is extruded with a drainage thread 6.

The permission bending radius of this cable is the outside diameter of cable 6 times; Can stand to exchange 50HZ, 3.5Kv/5min voltage and not breakdown.

The above is the utility model embodiment, and the equivalence of doing according to structure, feature and principle described in the utility model application range therefore all changes or modifies, and is included in the utility model patent claim.
