Description
Technical field
The present invention relates to field of cables, particularly relate to a kind of low-smoke halogen-free flame-retardant isolating cable.
Background technology
At present; along with the development of science and technology; the demand of people to cable also gets more and more; cable is a kind of common data-signal transmission equipment; have that message capacity is large, transmission stability is high and the advantage such as security performance is good; but existing cable covering uses some comparatively general polymer; not only useful life is short; and the situation of contaminated environment can be there is; some environmentally harmful materials can be produced in the use of cable; and can impact the healthy of people, can not use for a long time.
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 low-smoke halogen-free flame-retardant isolating cable.
The present invention takes following technical scheme to realize: a kind of low-smoke halogen-free flame-retardant isolating cable, and it comprises cable body, and described cable body comprises conductor, insulating barrier, screen and oversheath, and the cross section of described cable body is circular configuration; Described cable body inside is provided with many conductors; Described conductor outer wrapping layer protective layer; Described protective layer and conductor form cable core jointly; Described cable core closely extrudes a layer insulating outward; Gap portion between described insulating barrier and cable core is provided with packed layer; One deck screen is extruded outside described insulating barrier; Described screen is extruded with aluminium from inside to outside successively and gathers bonding sheath and reinforced layer; Described reinforced layer is outside equipped with oversheath; One deck intermediate gelatine layer is provided with between described oversheath and reinforced layer.
Above-mentioned a kind of low-smoke halogen-free flame-retardant isolating cable, described conductor adopts real core copper core or multiply to press copper core and makes, and its cross sectional shape is circular or sector structure.
Above-mentioned a kind of low-smoke halogen-free flame-retardant isolating cable, the protective layer of described conductor outer wrapping has acrylic acid ester emulsion roller coat to make.
Above-mentioned a kind of low-smoke halogen-free flame-retardant isolating cable, the reinforced layer that described cable body inside is arranged is that stainless steel wire braiding forms, and is network structure.
Above-mentioned a kind of low-smoke halogen-free flame-retardant isolating cable, described insulating barrier adopts ceramic silicon materials to make.
