Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

A kind of power cord with safeguard function as shown in FIG. 1 to FIG. 3, including wire body 1, further include protective layer 5, the wire body 1 is wrapped by multiple mutually twisted bunchys of the conductor 11 for being enclosed with shielded layer 2 and insulating layer 3, the shielded layer 2 Internal shield 21 and external shielding layer 22 are included, the insulating layer 3 is set between internal shield 21 and external shielding layer 22, the insulation Layer 3 includes inner insulating layer 31 and insulating outer layer 32, and the protective layer 5 is sheathed on the outside of wire body 1, the protective layer 5 with Foaming layer 4 is provided between wire body 1,5 from-inner-to-outer of protective layer sets gradually as fireprotection layer 51, damp-proof layer 52, resists Grind layer 53.

Furthermore, the inner insulating layer 31 uses polyethylene insulation material, and the insulating outer layer 32 uses polyolefin Insulating materials, insulating layer 31 are inside and outside double-layer coextrusion structure, by double-layer insulating structure, ensure that the physical property and electricity of electric wire Gas performance greatly improves electric wire security performance and unfailing performance in use.

Furthermore, the foaming layer 4 has good filler packet by EVA foam electric wire material extrusion moulding, EVA resin Capacitive and cross linkable.

Furthermore, 51 from-inner-to-outer of fireprotection layer sets gradually as thermal insulation layer and flame-retardant layer.

Furthermore, the thermal insulation layer uses ABS plastic material, and the flame-retardant layer uses bromine series flame retardant material.ABS modeling Material is the terpolymer of three kinds of acrylonitrile, butadiene and styrene monomers, acrylonitrile can effectively improve chemical resistance with it is resistance to Hot, butadiene, which can effectively improve elasticity and toughness, styrene, can be effectively improved electrical property, so as to effectively improve this The heat resistance of electric wire makes the electric wire still be able to normal use under the high temperature conditions.Bromide fire retardant has preferable affine Power, at the same it is nonflammable under certain condition, effectively increase the anti-flammability of the electric wire.
