Background technology
The fast development of country be unable to do without the development of communications industry, it is big to state wife and children to person-to-person communication be always the most important thing,
The development of communications industry be unable to do without the development of electric wire, the unavoidable generation for having fire in people's life, and fire can burn
Cable and burning due to cable, mutually between the electric wire obtained closely short circuit can be caused to cause bigger fire, so
Need the cable of design anti-flammability.Flame retardant cable is possible to be burned and can not run in case of fire, but can prevent the intensity of a fire
Sprawling.Generally, electric wire can be limited in burning in subrange just in case catching fire, not produce sprawling, keep others
Various equipment, avoid resulting in greater loss, the method that flame-retardant electric wire and cable typically uses is exactly in insulation, sheath and filling etc.
Halide and metal oxide containing halogen are added in material, is evaluated from fire-retardant angle, this is fabulous method, but
It is, due to containing halide in these materials, to discharge substantial amounts of smog and hydrogen halide in burning, so, during fire
Low visibility, safe escape and fire hose to personnel carry out very big obstruction, and people then more dies of asphyxiation for toxic gas,
So the improvement design of flame retardant cable is just very necessary.
The content of the invention
It is an object of the invention to provide a kind of simple in construction, anti-flammability greatly improves, and improves visibility during burning, avoids
The flame retardant cable that toxic gas damages to people, to solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides following technical scheme：
A kind of flame retardant cable, including oversheath, inner sheath, flame-retardant layer, glass layer, external insulation layer, conductor, inner insulating layer,
Screen layer and inorganic filling material；The oversheath, flame-retardant layer, glass layer, external insulation layer and inner sheath from outside to inside according to
Secondary setting；The inner side of the inner sheath is filled with inorganic filling material；At least four are equipped with the inorganic filling material to lead
Body, the outside of conductor are enclosed with inner insulating layer and screen layer successively.
Further：The thickness of the oversheath is 2~3 times of inner sheath thickness, and oversheath and inner sheath adopt polychlorostyrene
Vinyl material.
Further：The flame-retardant layer is gasket for packing, and gasket for packing opens net polypropylene tearing material using non-.
Further：The thickness of the glass layer is 0.3~0.5mm.
Further：The external insulation layer uses 105 DEG C of irradiated crosslinking low-smoke and halogen-free flame retardant polyolefin materials of environment-friendly type, interior
Insulating barrier uses 105 DEG C of IXPE materials of environment-friendly type.
Compared with prior art, the beneficial effects of the invention are as follows：The cable jacket and inner sheath of the present invention uses bullet
Property and all preferable pvc material of flexibility, the chlorination hydrogen amount generated during burning is only the 1/5 of common flame-proof polyvinyl chloride,
The corrosion of the organ stimulating and equipment to people can be greatly reduced；Flame-retardant layer enhances the fire retardant performance of cable；Glass fibre
Layer can strengthen the stress-bearing capability of cable, make its more tension, improve its intensity；Inorganic filling material ensures internal conductor structure
It is stable；The present invention is simple in construction, and anti-flammability greatly improves, and a large amount of smog will not be produced during burning, improves visibility, avoids simultaneously
Toxic gas damages to people.
