Abstract
The utility model discloses a kind of low-smoke halogen-free flame retardant cables; including insulated core and protective layer; the insulated core is made of conductor, insulating layer and separation layer; the conductor is aluminum conductor core, and the protective layer is from inside to outside successively by flame resistant filler layer, liner layer, inner sheath, armor, oversheath.The utility model low-smoke halogen-free inflaming-retarding cable, is combined using multilayer material, simple in structure, and insulating layer uses EP rubbers, humidity, resistance to oxidation；Its armor can keep off fire using metal material, can also enhance the intensity of cable, protect cable；Separation layer, liner layer, inner sheath, the oversheath of use are bittern-free flame-proof material, there is good anti-flammability and fire resistance, when burning not to generate halogen toxic gas, only a small amount of smog greatly improves personnel's survival rate in fire incident.
Description
Technical field
The utility model is related to field of cable technology, especially a kind of low-smoke halogen-free flame retardant cable.
Background technology
Cable is typically to be made of the additional protective layer of conductive wire.Cable be widely used in building, petrochemical industry,
The places such as iron, market, office building, dosage is larger, more demanding to quality, especially particularly important in fire-retardant, fire protecting performance, existing
Some flame retardant cables mostly use greatly halogen rubber or plastics and will produce a large amount of dense smoke when fire occurs as protective layer, and
And with halogen corrosive gas, this gas can not only damage equipment, building, but also it is strong to seriously endanger human body
Health.
