Abstract
The utility model relates to a concentric conductor branched cable, which belongs to the electric cable field and comprises a main cable core, a branched cable core, a sheath, a connecting body and a sheath of the connecting body. The branched cable core is connected with the main cable core via the connecting body. The main cable core and the branched cable core are respectively provided with a concentric conductor layer. The concentric conductor layers of the main cable core and the branched cable core are fixed and connected with the point of the connecting body. The utility model has the advantages of compact and reasonable structure, easy manufacture and low cost. A shield is formed at the outer part of the insulated cable core on the concentric conductor layers, so the functions of the anti electromagnetic interface and anti thunderbolt are achieved. The utility model has low and even positive (negative) sequence and zero sequence working impedance which is beneficial to improve the quality of a power supply. The utility model has the advantages of good sealing performance of the joint, moisture proof, water proof, good flexibility, very excellent anti-vibrating performance, long service life, small installing space, stable performance, factory prefabrication and short construction period without maintenance.
Description
Technical field
The utility model relates to a kind of structure of branch cable, belongs to the cable technology field.
Background technology
Existing branch cable mainly is made of conductor, insulation, filling, sheath, connected body sheath, jockey etc., and kind is more, divides polyvinyl chloride insulation, crosslinked polyetylene insulated by the insulation mode of product; Be divided into single core pattern, stranded type and multi-core integrated type by frame mode; Be divided into plain edition, fire safe type, flame retardant type etc. by function.The branch cable operation conditions is good, because its tree structure mode is convenient to installation, and the moistureproof and waterproof function admirable, installation takes up room little, and easy for installation, can save construction period, saves engineering cost significantly.But anti-electromagnetic interference of existing branch cable and anti-lightning strike performance are poor, influence performance and safety that branch cable uses.
The utility model content
The purpose of this utility model is exactly at existing branch cable above shortcomings, and a kind of concentric conductor branch cable with anti-electromagnetic interference and anti-lightning strike function is provided.
The purpose of this utility model is to realize by the improvement to existing branch cable, concentric conductor branch cable, comprise main cable core, branch cable core, sheath, connected body, connected body sheath, the branch cable cable core connects the main cable cable core by connected body, it is characterized in that being respectively equipped with the concentric conductor layer on main cable cable core and the branch cable cable core, the concentric conductor layer on the main cable cable core is fixedlyed connected at the connected body place with the concentric conductor layer on the branch cable cable core.
Described main cable cable core is provided with three at least by the insulated wire cores that insulating barrier constitutes is set on the conductor.The concentric conductor layer is stranded in by the copper single line that meets GB/T3953 regulation on the inner covering of insulated wire cores outside and constitutes.Being fixedly connected as crimping connects or is welded to connect.Also be provided with band and inner covering on the cable core in the concentric conductor layer, band is wrapped on cable core, and inner covering is arranged on the band.
The utility model compactness rational in infrastructure is manufactured easily, and cost is low.Concentric conductor branch cable is owing to the uniqueness of its structure, and the PE line of multi-core integrated cable changes the outer conductor of concentric conductor cable into, and the concentric conductor layer forms shielding outside a few eradication edge cores, and it has anti-electromagnetic interference and anti-lightning strike function.Product has lower and uniformly just (contrary) preface and zero sequence working impedance, helps improving power supply quality; More much lower than the reactance value of common quad under the zero sequence operating state, help the sensitivity action of short circuit automatic safety device; Joint tighness is good, moistureproof, waterproof; Flexible good, have good vibrationproof performance, service life is long; Compact, installation takes up room little; Stable performance, non-maintaining; Prefabrication shortens construction period.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a section structure schematic diagram of the present utility model;
Among the figure: 1 conductor, 2 insulation, 3 fill 4 bands, 5 inner coverings, 6 concentric conductor layers, 7 bands, 8 sheaths, 9 connected body sheaths, 10 connected bodies.
Embodiment
The TR type copper single line that employing meets the GB/T3953 regulation is twisted into conductor 1, and parcel XLPE insulation 2 constitutes insulated wire cores on conductor 1.Adopt three eradication edge cores to be twisted into cable core.The insulated wire cores that the main cable cable core adopts is thicker, and the insulated wire cores that the branch cable cable core adopts is thinner.Twining package tape 4 and inner covering 5 is set on stranded stranding cable core adopts the stranded concentric conductor layer 6 of copper single line that meets the GB/T3953 regulation on inner covering 5, the concentric conductor layer conductor uses mainly as the PE line, and good shield electromagnetic interference and anti-lightning strike effect are arranged.Be provided with in the cable core gap in band 4 and fill 3.Twining package tape 7 on concentric conductor layer 6.Sheath 8 is set on band 7, and sheath 8 adopts polyvinyl chloride, polyethylene or halogen-free and low-smoke flame-retardant polyolefin material extrusion molding.The branch cable cable core adopts connector 10 to be connected with the main cable cable core, and connector 10 is the C clamp tool, and this anchor clamps copper material should be not less than the regulation of No. two copper of GB/T5231 (T2).Concentric conductor layer on concentric conductor layer on the main cable cable core and the branch cable cable core is in connector 10 places crimping or weld and fixedly connected.On the sheath 8 on the connector 10 and connector place, connected body sheath 9 is set, the connected body sheath material is according to the classification of cable jacket material, adopt corresponding injection grade material, guarantee that connected body sheath 9 materials are consistent with cable cover(ing) 8 materials, both are in conjunction with tight.
