Abstract
A novel concentric conductor branch cable comprises a main cable core, a branch cable core, a concentric conductor layer, a sheath, a branch connecting body and a connecting body sheath. The branch cable core is connected with the main cable core through the connecting body; the concentric conductor layer is respectively intertwisted on the main cable core and the branch cable core. The novel concentric conductor branch cable is characterized in that: the conductors of the main cable core, the branch cable core and the concentric conductor layer are copper single lines which meet the specification of GB/ T3953; the copper single line of the concentric conductor layer on the main cable core is divided into two parts to be symmetrically intertwisted on the cable core; a symmetric space is arranged between the two parts of the copper single line and a filler is arranged in the space. The novel concentric conductor branch cable has simple and compact structure, easy manufacturing, low cost, and good service performance. The novel concentric conductor branch cable not only can prevent electromagnetic interference and lightning and improve power supply quality, but also has flexibility and good anti-vibration property. The novel concentric conductor branch cable has good joint sealing, moisture proof and waterproof properties, stable use performance and long service life.
Description
Technical field
The present invention relates to the structure of a kind of branch cable, particularly concentric conductor branch cable, belong to the cable technology field.
Background technology
Existing concentric conductor branch cable is mainly by main cable core, branch cable core, sheath, connected body, connected body sheath, the branch cable core connects the main cable core by connected body, on main cable core and the branch cable core concentric conductor layer is set respectively, the concentric conductor layer on the main cable core is fixedlyed connected at the connected body place with the concentric conductor layer on the branch cable core.This concentric conductor branch cable, compactness rational in infrastructure, 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, have anti-electromagnetic interference and anti-lightning strike function.Product has lower and uniformly just (contrary) preface and zero sequence working impedance, improves power supply quality.Joint tighness is good, moistureproof, waterproof, and service life is long.But the concentric conductor layer of this concentric conductor branch cable has absolutely surrounded the main cable core, and the flexibility of cable and impact resistance need further to improve and improve.
Summary of the invention
Purpose of the present invention is exactly at existing concentric conductor branch cable above shortcomings, and a kind of shock proof novel concentric conductor branch cable with softness of anti-electromagnetic interference, anti-lightning strike function is provided.
The object of the present invention is achieved like this, novel concentric conductor branch cable, comprise the main cable core, the branch cable core, the concentric conductor layer, sheath, branch's connected body, the connected body sheath, the branch cable core connects the main cable core by connected body, the concentric conductor layer is stranded in respectively on main cable core and the branch cable core, it is characterized in that described main cable core, the conductor of branch cable core and concentric conductor layer is the copper single line that meets the GB/T3953 regulation, the copper single line of the concentric conductor layer on the main cable core is divided into two parts symmetry and is stranded on the cable core, between two parts copper single line symmetric neutral is arranged, be provided with filler in the neutral.
Also be provided with band and inner covering on the cable core in the described concentric conductor layer, inner covering adopts polyvinyl chloride or polyethylene or halogen-free and low-smoke flame-retardant polyolefin material extrusion molding on band.
Described branch connected body is the extended type structure, and the material of branch's connected body is not less than the regulation of No. two copper of GB/T5231 (T2).
The present invention's compactness rational in infrastructure is simple, manufactures easily, and cost is low, and serviceability is good.Novel concentric conductor branch cable is because the uniqueness of its structure: the copper single line of the concentric conductor layer on the main cable core is divided into two parts symmetry and is stranded on the cable core, between two parts copper single line symmetric neutral is arranged, be symmetric form 2/3 structure, the copper single line that is the concentric conductor layer is covered with 2/3 of main cable core periphery, be provided with filler in the neutral, promptly 1/3 of main cable core periphery is filler.This cable had both had anti-electromagnetic interference and anti-lightning strike function, had lower and uniformly just (contrary) preface and zero sequence working impedance, improved power supply quality.Joint tighness is good, moistureproof, waterproof.Have flexible and good vibrationproof performance again, installation takes up room little, stable performance, and service life is long, and is non-maintaining.Prefabrication shortens construction period.
The novel concentric conductor cable is a type that multi-core integrated cable grows up, and difference is that the PE line of multi-core integrated cable changes the outer conductor of novel concentric conductor cable into, and the concentric conductor layer is stranded in other according to symmetrical 2/3 structure and becomes outside the cable core.It is stranded in becoming on the cable core to be that concentric conductor layer conductor is divided into two parts symmetries, and symmetry reserves two place's neutrals, in stranded process, increases twisting pitch, and the concentric conductor layer is a helical structure in whole cable, and its field intensity is symmetrical.The concentric conductor layer forms screen, plays anti-electromagnetic interference and anti-lightning strike function.
