Abstract

The invention discloses an environment-friendly type high-temperature-resistant and fireproof insulating cable. The cable is composed of wire cores, a fire-resistant mica tape, an inner sheath layer and an outer sheath layer. The wire cores are formed by arranging shielding layers and insulating layers outside the wire cores in an extruding mode. The wire cores, the insulating layers and the shielding layers form cable cores, and four ground wire cores are arranged among the cable cores. High-temperature-resistant glass silk is arranged between the inner sheath layer and the cable cores and forms a filling layer. The inner sheath layer is formed by closely arranging the outer sheath layer, a stainless steel wire braided armoring layer and the fire-resistant mica tape from outside to inside in an extruding mode. The cable has the advantages of being good in shielding performance, resistant to high temperature, high in electric conductivity, good in environment friendliness and the like.

Description

A kind of environment-friendly high-temperature fire-proof insulation cable
Technical field
The present invention relates to field of cables, relate 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.
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 environment-friendly high-temperature fire-proof insulation cable.
The present invention 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 features such as the present invention has following beneficial effect in sum: this cable has good shielding properties, high temperature resistant, and conductance height and the feature of environmental protection are good.
Brief description of the drawings
Fig. 1 is cross-sectional structure schematic diagram of the present invention;
Wherein: 1, core; 2, insulating barrier; 3, screen; 4, inner restrictive coating; 5, fire-resistant isinglass belt; 6, stainless steel wire braiding armour; 7, oversheath; 8, wire core; 9, packed layer.
Embodiment
As shown in Figure 1, a kind of environment-friendly high-temperature fire-proof insulation cable, it is to be made up of core 1, inner restrictive coating 4, fire-resistant isinglass belt 5 and external sheath layer 7, described core 1 is outer is to be extruded and formed by screen 3 and insulating barrier 2; Described core 1, insulating barrier 2 and screen 3 form cable core; In the middle of described cable core, be provided with four ground wire cores 8; Between described inner sheath 4 and cable core, be provided with pyroceram silk and form packed layer 9; Described inner sheath 4 ecto-entads are closely extruded and form by oversheath 7, stainless steel wire braiding armour 6 and fire-resistant isinglass belt 5; The count of described stainless steel wire braiding armour 6 is no less than 90%; Described core 1 is to form by multiply tinned copper wire is stranded; The material of described inner sheath 4 is silicon rubber.
The above is embodiments of the invention, and the equivalence of doing according to structure, feature and principle described in the present patent application scope therefore all changes or modifies, and is included in patent claim of the present invention.
