Abstract

The utility model discloses a heatproof flexible cable, and the cable mainly comprises nickel cable cores, a filling layer, an aluminium-tape wrapping layer, a sheath layer, and a copper cable core. The interior of the filling layer is equipped with three groups of nickel cable cores in an extruding manner. Each nickel cable core sequentially comprises a nickel conductor, an insulating layer, and an aluminium-tape shielding layer from the inside to the outside. The filling layer is wrapped by the aluminium-tape wrapping layer. The cable provided by the utility model is widely used for the power and control circuits of machine furnaces in an iron and steel plant, a copper smelting plant, a continuous casting machine, and a heat-engine plant. The cable is excellent in performance of resistance to high-temperature radiation, is strong in performance of anti-electromagnetic interference, and is good in shielding performance.

Description

A kind of heat-resisting flexible cable

Technical field

The utility model belongs to field of cables, relates in particular to a kind of heat-resisting flexible cable.

Background technology

At present, along with socioeconomic development, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as the cable using in the fields such as the power at steel plant, copper smelting plant, conticaster and thermal power plant turbine-boiler or control circuit, all high especially to the requirement of the useful life of cable, anti-electromagnetic interference, shielding properties and resisting radiation interference aspect of performance, only meet the requirements, could improve in these fields the fail safe while manufacturing.

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 high temperature resistant radiance, the heat-resisting flexible cable of advantages of good shielding performance.

The utility model takes following technical scheme to realize: a kind of heat-resisting flexible cable, it mainly comprises nickel cable core, packed layer, aluminium strip belting layer, restrictive coating and copper cable core, described packed layer inside is extruded with three groups of nickel cable cores side by side, described nickel cable core is followed successively by nickel conductor, insulating barrier and aluminium strip screen from inside to outside, and described packed layer is wrapped with one deck aluminium strip belting layer.

Described copper cable core is two, is arranged on uniformly in described packed layer, and every cable core is all comprised of copper conductor and chain armour.

In described restrictive coating, be extruded with a copper body heating wire.

The utlity model has in sum following beneficial effect: the utility model is widely used in power or the control circuit of steel plant, copper smelting plant, conticaster and thermal power plant turbine-boiler, there is good high temperature resistant radiance, and it is strong to have anti-electromagnetic interference, the advantage of advantages of good shielding performance.
