Abstract

The utility model discloses an environmentally friendly high temperature and fire preventing insulation cable which comprises wire cores, a fireproof mica tape, an inner sheath layer and an over-sheath layer. The wire core is wrapped tightly by a shielding layer and an insulation layer; the wire core, the insulation layer and the shielding layer constitute a cable core. Four ground wire cores are arranged among the cable cores. A filling layer, composed of high temperature withstanding glass fibers, is arranged between the inner sheath and the cable cores. The inner sheath is wrapped tightly and successively from outside to inside by the over-sheath, a stainless steel wire woven armored layer and a fire retardation mica tape. The cable has a sound shielding performance, is capable of withstanding high temperature, has a high conductivity and is environmentally friendly.

Description

A kind of environment-friendly high-temperature fire-proof insulation cable
Technical field
The utility model relates to field of cables, relates in particular to a kind of environment-friendly high-temperature fire-proof insulation cable.
Background technology
At present, along with scientific and technical development, also there are various changes in the function of cable, the cable of traditional sense only only has the effect of conduction, the protective capacities of itself is too weak, once face fire or hot environment, cable will become the existence that threatens human life's safety, also can affect work and benefit in these fields.
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 environment-friendly high-temperature fire-proof insulation cable.
The utility model takes following technical scheme to realize: a kind of environment-friendly high-temperature fire-proof insulation cable, and it is to be made up of core, fire-resistant isinglass belt, inner restrictive coating and external sheath layer, described core is outward to be extruded and formed by screen and insulating barrier; Described core, insulating barrier and screen form cable core; In the middle of described cable core, be provided with four ground wire cores; Between described inner sheath and cable core, be provided with pyroceram silk and form packed layer; Described inner sheath ecto-entad is closely extruded and forms by oversheath, stainless steel wire braiding armour and fire-resistant isinglass belt; The count of described stainless steel wire braiding armour is no less than 90%; Described core is to form by multiply tinned copper wire is stranded; The material of described inner sheath is silicon rubber.
The utlity model has in sum following beneficial effect: this cable has good shielding properties, high temperature resistant, the feature such as the high and feature of environmental protection of conductance is good.
