Embodiment

In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining The utility model, it is not used to limit the utility model.

Refer to a kind of novel power cable shown in Fig. 1, including an at least cored wire 1 from the inside to the outside, water blocking yarn 3, Fire prevention band 4, insulating barrier 5, waterstop 6, filler 7, inner sheath 8, armouring 9, oversheath 10, the water blocking yarn 3 are a kind of new Type expands water blocking yarn 3, and the fire prevention band 4 is formed for porcelain composite materials, and the waterstop 6 is to be coated without powder super-absorbent Band is formed, and the armouring 9 is the chain armouring 9 of aluminum alloy strip, and the oversheath 10 includes PET twining package tape from inside to outside, The twining package tape is wrapped with woven wire cloth, and the woven wire cloth is wrapped with rubber protecting jacket, the oversheath The frost retarding layer of high temperature insulating thermal insulation coatings either reflecting heat insulation paint is also coated with 10.

One layer of insulated paint 2 is also coated with the cored wire 1, the insulated paint 2 is coated directly on cored wire 1, and stability is good, works as outside Insulating materials when being destroyed, second protection can be played a part of, prevent short circuit.

The insulating barrier 5 is formed for pvc material, and polyvinyl chloride insulation is simple in construction, and system is easy to process, in light weight, Lay it is easy for installation, not by laying drop limited.

The fire prevention filler 7 is magnesia filler.

The inner sheath 8 is formed for polythene material, and the protecting effect of the polythene material is fine, can adapt to a variety of Environment.

One layer of insulated paint 2 is scribbled outside the cored wire 1 of the cable, when generation fire, water inlet or by dangerous situations such as external force destructions When, if the polyvinyl chloride insulation damage of outer layer, the insulating barrier 5 play a part of to protect to the end, prevent short circuit；The insulated paint Expansible water blocking yarn 3 is provided with outside 2, this speed of expansion of water blocking yarn 3 is fast, and the chemical stability that water suction forms gel is good, by force Degree is high, and chemical stability is good, and resistance to bacterium and mould, heat endurance is good, good weatherability, adapts to various following process and makes and various Use environment, there is good compatibility with other materials；Fire prevention band 4, the fire prevention band 4 are provided with outside the water blocking yarn 3 Insulated using porcelain complex mineral, can effectively prevent injury of the high temperature caused by flame to cored wire, also act as last layer The effect of insulation protection, while it also plays the speed for delaying flame combustion, such structure, it plays protection cored wire Insulation air-tightness is also formed simultaneously, and flame can only be in burning of the external firing without forming penetrability；Outside the fire prevention band 4 It is provided with polyvinyl chloride insulation layer 5；Waterstop 6 is provided with outside the polyvinyl chloride insulation layer 5, the waterstop 6 is to surpass without powder Level absorbs coated, and this band is relatively thin, so that optical cable is thin and light, and the available coating method for being different from commonly using；It is every above The protective layer of the outside of root cored wire 1, the tangent placement of protective layer of each cored wire 1, filling is provided with the protective layer outer void Thing 7, the filler 7 are magnesia filler；Armouring 9 is provided with outside the protective layer of the cored wire 1, the armouring 9 closes for aluminium The chain armouring of gold ribbon, this material have good decay resistance；The oversheath 10 include PET from inside to outside around Band, the twining package tape are wrapped with woven wire cloth, and the woven wire cloth is wrapped with rubber protecting jacket, therefore Harm during burning to environment can be also preferably minimized, and inorganic mineral insulation fireproof cable can ensure emergent make after installing With usually can also being used as heatproof 125 DEG C of halogen-free flame-retardant cables, fire-resisting cables, both overcome rigid magnesium oxide mineral insulation electricity The defects of cable, the advantage of chain Sheathed metal set has been played again, has reached short circuit and does not burn, burn the effect of not short-circuit；It is and outer Woven wire cloth on sheath has greatly reinforced the ageing resistance of cable, so as to extend service life.Such as in low temperature ring Used in border, the frost retarding layer of high temperature insulating thermal insulation coatings either reflecting heat insulation paint can be applied on oversheath 10.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
