Description
Technical field
The utility model belongs to building appliance technical field, is specifically related to a kind of cable for building.
Background technology
At present, band-armored is widely used in electric power conveying, and along with the increase of story height, the band-armored being originally used for tiling appears at the occasion of vertical hanging more and more.The object of steel-tape armouring is to reduce in work progress and article sharp-pointed in use procedure; such as pick and shovel; cable is directly destroyed; avoid because cable insulation damage layer cause electric leakage, the generation that the phenomenon such as to puncture; simultaneously, steel-tape armouring can also protect cable biting from rodent such as mouse, because cable is embedded in underground; the support of cable does not need to be realized by the pulling force of self, and therefore the tensile property of this cable does not often need unsettled cable so large.At the position of cable vertical hanging, cable produces internal tension under the effect of self gravitation, and this part pulling force is often concentrated and put on cable inner conductive copper cash, by long accumulation effect, causes adverse influence to the conductive capability of cable.
Utility model content
The purpose of this utility model is to provide a kind of cable for building, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of cable for building, comprise wire, wire insulation, wire fireprotection layer, packed layer, strengthening core, water blocking layer, tensile steel wire rope, screen, first armour, second armour, resistance to compression salient point and oxygen barrier layer, the outer end of described wire is enclosed with wire insulation, the outer end of described wire insulation is enclosed with wire fireprotection layer, strengthening core is provided with between described wire, the outer end of described oxygen barrier layer is enclosed with water blocking layer, the outer end of described water blocking layer is enclosed with screen, the outer end of described screen is enclosed with the first armour, the inside of described first armour is provided with root tensile steel wire rope, the outer end of described first armour is enclosed with the second armour.
Preferably, the described packed layer be made up of silica dioxide granule is provided with between described wire fireprotection layer and oxygen barrier layer.
Preferably, the surface of described second armour is intensive resistance to compression salient point.
Preferably, the Thickness Ratio between described second armour and the first armour is 2:1.
Technique effect of the present utility model and advantage: this cable for building utilizes the effect of strengthening core, tensile steel wire rope and resistance to compression salient point to strengthen pull resistance and the crushing resistance of cable, and in building, result of use is good, long service life.
