Description

A kind of interim aerial cable of construction

Technical field

The utility model is related to field of cable technology, more particularly to a kind of interim aerial cable of construction.

Background technology

Construction temporary cable refers to erecting the cable used, in the construction process, Hen Duo electricity temporarily in construction site Cable is all that exposed ground, the wall of being suspended on either tows on ground, wall or rolled, collide by machinery equipment.It is existing Product because using routinely material and routinely structure design, i.e., protected using the insulation of former inner wire outer cladding polyvinyl chloride The structure of sheath often cannot be satisfied above-mentioned requirements in this way, the perishable cracking of protective layer during use, can not bear over long distances It is aerial to use, construction site dragging or the collision of machine can not be avoided to cause the security risk scratched, it is therefore desirable to from often replacing Change cable, ensured with this it is safe to use, but thus easily cause resource waste.

Invention content

The utility model can have mainly solving the technical problems that providing a kind of interim aerial cable of construction Effect avoids product from being scraped off damage, anti-extrusion in dragging process, and tensile strength is promoted, and product subsurface can be pullled arbitrarily.

In order to solve the above technical problems, the technical solution that the utility model uses is：A kind of construction is provided to face When aerial cable, including inner wire further includes the reinforcing braid of insulating layer and inner wire outermost layer cladding, the insulating layer packet It includes and insulate one layer with two layers of insulation, one layer of the insulation is coated on outside inner wire, and two layers of insulation, which is coated on, insulate outside one layer, reinforces Braiding layer is coated on outside two layers of insulation, and the reinforcing braid includes steel wire floor and is uniformly wrapped on the nylon of steel wire layer surface Layer.

Further, the steel wire floor selects the steel wire of a diameter of 0.08mm；

Further, the inner wire is formed using more copper wire pair twists；

Further, each copper wire be surface pass through coating bare copper wire, the coating by nickeline mix and At；

Further, the material of one layer of the insulation is high temperature polyvinyl chloride；

Further, the material of two layers of the insulation is nylon.

The utility model has the beneficial effects that：Existing product stress original paper during aerial use is former inner wire, Compared to the prior art, the utility model is aerial using the reinforcing braid that force-summing element is outermost layer addition, can not only hold Conducted oneself with dignity by long range, realize the aerial laying of long range, moreover it is possible to which on all kinds of building surfaces pull will not scratch, and can also hold It rolled, collided by machinery equipment, for product more resistant to extruding, tensile strength is big, and surface layer can arbitrarily pull, and effectively avoids electric leakage wind Dangerous, in addition reinforcing braid coats one layer of nylon layer particular by steel wire layer surface, plays and one layer of insulation, two layers of insulation Mutually insulated acts on, and the material of one layer of insulation uses polyvinyl chloride, and in this way more resistant to high temperature, the material of two layers of insulation uses nylon, There is preferable corrosion-resistant, acid and alkali-resistance effect.

Fig. 3 is the structural schematic diagram of the reinforcing braid of the interim aerial cable of the utility model construction；

The label of each component is as follows in attached drawing：1, former inner wire 2, insulating protective layer 3, inner wire 4, one layer 5 of insulation, Two layer 6 of insulation, reinforcing braid 7, steel wire floor 8, nylon layer.

Specific implementation mode

The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear to be made to the scope of protection of the utility model Define.

Referring to Fig. 1, the utility model embodiment includes：Inner wire 3 further includes 3 outermost layer packet of insulating layer and inner wire The reinforcing braid 6 covered, the insulating layer include two layer 5 of one layer 4 of insulation and insulation, and the insulation is coated on inner wire 3 for one layer 4 Outside, it insulate two layer 5 to be coated on and insulate outside one layer 4, reinforcing braid 6, which is coated on, to insulate outside two layer 5, and the reinforcing braid 6 wraps Include steel wire floor 7 and the nylon layer 8 for being uniformly wrapped on 7 surface of steel wire floor.

Further, the steel wire floor 7 selects the steel wire of a diameter of 0.08mm；

Further, the inner wire 3 is formed using more copper wire pair twists,

Further, each copper wire be surface pass through coating bare copper wire, the coating by nickeline mix and At；

Further, the material to insulate one layer 4 is high temperature polyvinyl chloride；

Further, the material to insulate two layer 5 is nylon.

Existing product stress original paper during aerial use is former inner wire 1, and compared to the prior art, this practicality is new Type frame sky can not only bear the dead weight of long range using the reinforcing braid 6 that force-summing element is outermost layer addition, realize it is long away from From aerial laying, moreover it is possible on all kinds of building surfaces pull will not scratch, and can also bear machinery equipment and roll, collide, For product more resistant to extruding, tensile strength is big, and surface layer can arbitrarily pull, and effectively avoids electric leakage risk, and in addition reinforcing braid is specifically By coating one layer of nylon layer 8 in 7 surface of steel wire floor, play the role of and two layer of 5 one layer 4 of insulation, insulation mutually insulated, insulation one The material of layer 4 uses polyvinyl chloride, and in this way more resistant to high temperature, the material that two layer 5 of insulation uses nylon, has preferable corrosion-resistant, resistance to Acid-base function.

The above description is only the embodiments of the present invention, and it does not limit the scope of the patent of the present invention, every Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in Other related technical areas are equally included in the patent within the scope of the utility model.
