Description
Technical field
The present invention relates to technical field of electric wires and cables, particularly a kind of sector cable.
Background technology
Electric wire by industrial production, life etc. almost in each field use.Yet existing single-phase or multi-phase cable is to adopt circular cable conductor, coated insulation layer on conductor then, and then allow many stranded backs of insulating barriers or be positioned over abreast finish making in the sheath.This cable is called a kind of beaming type branch cable in name, and the patent No. is that the Chinese patent of ZL200720142382.7 is open.This cable is owing to adopt circular insulating barrier, and occupation space was bigger when therefore placed many parallel placements or stranded back, so the external diameter of sheath is thicker, and material consumption is more, and cost is bigger, need a large amount of man-hours when laying, and occupation space is big.
Summary of the invention
In order to address the aforementioned drawbacks, the invention provides a kind of sector cable, it is realized by the following technical solutions:
Sector cable, it comprises at least: two insulating barriers 2 and the restrictive coating 4 that is extruded in outside the insulating barrier 2 that are coated on outside the conductor 1; It is characterized in that: conductor 1 forms and the cross section of conductor 1 is fan-shaped by many one metal wires are stranded, and the cross section of insulating barrier 2 is similar to the cross section of conductor 1 fan-shaped; Little gapped between the adjacent insulating barrier 2, all insulating barriers are arranged any cross section sub-circular or the ellipse that forms; Be positioned in parallel to each other within the restrictive coating 4 between the insulating barrier 2.
The wire of above-mentioned formation conductor 1 is planted the copper cover aluminum composite filament or is included above-mentioned two or more wire arbitrarily for single bare copper wire or list kind tinned copper wire or single zinc-plated copper wire or single kind aluminium wire or list of planting of planting.
Further, above-mentioned described single kind diameter wiry is 0.03mm～1.0mm.
Further, above-mentioned described single kind diameter wiry is 0.03mm or 0.04mm or 0.05mm or 0.08mm or 0.10mm or 0.40mm or 0.50mm or 0.60mm or 0.80mm or 0.90mm or 1.0mm.
The material of above-mentioned described insulating barrier 2 is for being the plastics of base material with flame-proof polyvinyl chloride or low-smoke halogen-free polyolefin material or with the polyethylene; And its thickness range is 0.3mm～2.0mm.
The one-tenth-value thickness 1/10 of above-mentioned described insulating barrier 2 is 0.3mm or 0.5mm or 0.8mm or 1.0mm or 1.2mm or 1.6mm or 1.8mm or 2.0mm.
The material of above-mentioned described restrictive coating 4 is flame-proof polyvinyl chloride or low-smoke halogen-free polyolefin material or is the plastics of base material with the polyethylene; And its thickness range is 0.3mm～3.0mm.
The one-tenth-value thickness 1/10 of above-mentioned described restrictive coating 4 is 0.3mm or 0.5mm or 0.8mm or 1.0mm or 1.2mm or 1.6mm or 1.8mm or 2.0mm or 2.5mm or 2.8mm or 3.0mm.
Because the cross-sectional profile of insulating barrier 2 is fan-shaped, and a plurality of insulating barrier formation sub-circular or ellipse, therefore, compare with the round conductor insulating barrier of prior art, saved the space greatly, therefore, external diameter is thinner, it is more convenient to construct, and it is littler to take up room, and material is more saved; Be 30 amperes threephase cable equally, traditional outside diameter of cable reaches more than the 10mm, and cable of the present invention, its external diameter only is 8.2mm, correspondingly, along with the increase of burden requirement, the advantage that external diameter is littler is more obvious.In addition, because conductor has adopted many one metal wires stranded, so conductor is very soft; Therefore, although the cross section of conductor is fan-shaped, it still all is very easy to moulding in process of production in construction.
The present invention has the following advantages: simple in structure, external diameter is thinner, material consumption still less, lower, the space hold of cost still less, construction is more convenient.

Embodiment
Embodiment one
See also Fig. 1 and Fig. 2, sector cable, it comprises: three insulating barriers 2 and the restrictive coating 4 that is extruded in outside the insulating barrier 2 that are coated on outside the conductor 1; It is characterized in that: conductor 1 forms and the cross section of conductor 1 is fan-shaped by many one metal wires are stranded, and the cross section of insulating barrier 2 is similar to the cross section of conductor 1 fan-shaped; Little gapped between the adjacent insulating barrier 2, all insulating barriers are arranged any cross section sub-circular that forms; Be positioned in parallel to each other within the restrictive coating 4 between the insulating barrier 2.
Embodiment two
See also Fig. 3 and Fig. 4, sector cable, it comprises: four insulating barriers 2 and be extruded in the outer restrictive coating 4 of insulating barrier 2; Protective layer 3 is coated on outside the conductor 1, and protective layer 3 is positioned within the insulating barrier 2; It is characterized in that: conductor 1 forms and the cross section of conductor 1 is fan-shaped by many one metal wires are stranded, and the cross section of insulating barrier 2 is similar to the cross section of conductor 1 fan-shaped; Little gapped between the adjacent insulating barrier 2, all insulating barriers are arranged any cross section sub-circular that forms; Be positioned in parallel to each other within the restrictive coating 4 between the insulating barrier 2.
In above-mentioned arbitrary embodiment, the wire that constitutes conductor 1 is that single kind bare copper wire or list are planted tinned copper wire or list is planted zinc-plated copper wire or list kind aluminium wire or single kind copper cover aluminum composite filament or included above-mentioned two or more wire arbitrarily.
