What the utility model can reach has the technical effect that：
Compared with prior art, the anticreep electric wire of fire prevention of the present utility model, when electric wire catches fire, lead point
Combustion so that solid particle layer fully reacts, and penetrates thin sheath, sprays the sodium bicarbonate powder in sodium acid carbonate layer, bicarbonate
Sodium resolves into water, carbon dioxide and sodium acid carbonate in fire, plays a part of directly putting out a fire.Meanwhile, when circuit due to overload or
When person is short-circuit, it may occur that leaky, at this moment zero sequence current mutual inductor will work, and cut off the electricity supply, it is to avoid electric wire electricity
Cable causes fire.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
Fig. 1 is the structural representation of the anticreep electric wire of the utility model fire prevention.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
Referring to Fig. 1, a kind of anticreep electric wire of fire prevention, centre is three-phase copper conductor 1, and copper conductor 1 is exhausted by polyethylene
Edge layer 2 is wrapped up, and the polyethylene layer 2 is wrapped with explosion-protection equipment layer, explosion-protection equipment layer include insulation protection pad 3, on
Explosion-proof cylinder 4, under explosion-proof cylinder 5, the insulation protection pad 3 is wrapped in polyethylene layer 2, the outer circle explosion-proof under of insulation protection pad 3
Cylinder 5 is wrapped, under explosion-proof cylinder 5 be tightly sleeved with upper explosion-proof cylinder 4, the outer filled solid stratum granulosum 6 of explosion-protection equipment layer；It is described
Solid particle layer 6 is made up of sulphur, carbon, potassium nitrate solid particle, and a lead 7 is serially connected with the middle of solid particle layer 6；It is described solid
The periphery of body stratum granulosum 6 is enclosed with sodium acid carbonate layer 8, and the sodium acid carbonate layer 8 includes thin sheath 9, water-proof jacket 10 and filling
The sodium bicarbonate powder particle between thin sheath 9 and water-proof jacket 10 is arranged on, between solid particle layer 6 and water-proof jacket 10
If being additionally provided with main line set 11, lead 7 is through line set 11 and extends to water-proof jacket 10.
