Abstract

The invention discloses a multi-conductor insulated flexible cable which is composed of seven copper conductors, a polytetrafluoroethylene insulated layer, a tinned copper tape armor layer, a silicone rubber insulated layer, a nickel tape shielding layer and a chloroprene rubber protecting bush layer. The seven copper conductors are wrapped by the polytetrafluoroethylene insulated layer which is wrapped by the tinned copper tape armor layer, the tinned copper tape armor layer is wrapped by the silicone rubber insulated layer, and the silicone rubber insulated layer is wrapped by the nickel tape shielding layer. According to the cable, the temperature of mounting and laying of the cable is low, the service life is long, the cable has the advantages of resisting high temperature, and being good in insulation and flexible, and meanwhile the cable has the advantages that electrical stability is excellent under the high-temperature environment, and the conductive performance is excellent.

Description

A kind of many conductor insulations flexible cable

Technical field

The invention belongs to field of cables, relate in particular to a kind of many conductor insulations flexible cable.

Background technology

Cable refers to the wire of conduction current, is widely used in every field, in the middle of cable for aviation, indices to cable is had relatively high expectations, heat-resisting such as requiring to have, insulation, the characteristic of heat-resisting quantity and electric conductivity, just can be applied to, in the middle of aviation field, ensure safety.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of have heat-resisting, good insulation preformance, many conductor insulations flexible cable of resistant to elevated temperatures advantage.

The present invention takes following technical scheme to realize: a kind of many conductor insulations flexible cable, it is by copper conductor, teflon insulation layer, tin-coated copper strip armour, silicone rubber insulation layer, nickel strap screen and chloroprene rubber sheath layer form, it is characterized in that: described copper conductor is set to seven, outside seven copper conductors, wrap up one deck teflon insulation layer, outside described teflon insulation layer, wrap up one deck tin-coated copper strip armour, outside described tin-coated copper strip armour, wrap up one deck silicone rubber insulation layer, described teflon insulation layer inside is extruded with four groups of tinned copper conductor cable cores and four groups of nickel conductor cable cores, described tinned copper conductor cable core and nickel conductor cable core space arrange, described tin-coated copper strip armour inside is extruded with 8 aluminium alloy conductors, described silicone rubber insulation layer inside is extruded with 8 aluminium conductors.

The present invention has following beneficial effect in sum: this kind of cable installation temperature is low, long service life, have high temperature resistant, good insulating, soft advantage also has hot environment electric stability excellent, the feature that electric conductivity is excellent simultaneously.
