Abstract
The utility model discloses a branch cable in advance, including main cable and branch cable, treat the copper conductor silver brazing welding of the connection part department of branch of branch stand heart yearn among the branch cable copper conductor of branch cable one end and the main cable, branch's connection part periphery is to setting up the insulation shielding structure. The utility model discloses adopt silver -colored brazing welding on the conductor of branch cable in advance contact head, reduced resistance, improved the electric conductive property of joint department.
Description
Technical field
The utility model relates to a kind of pre-branched cable.
Background technology
Pre-branched cable is factory's cable by user's design drawing prefabricated branch line when producing main cable, branch line factory is manufactured on main cable in advance, branch line cross-sectional sizes and branch line length etc. determine according to designing requirement, advantage greatly shortens construction period, significantly reduce Master Cost and operating expenses, ensure that the reliability of distribution larger.Existing pre-branched cable joint generally adopts and compresses process, and joint conductor resistance is large, and electric conductivity is not ideal enough.
Utility model content
The purpose of this utility model is exactly to solve the problem, and provides a kind of joint resistance little, the pre-branched cable that electric conductivity is good.
To achieve these goals, the utility model adopts following technical scheme: a kind of pre-branched cable, comprises main cable and branch cable;
Described main cable has:
Heart yearn, it is formed by 2 ~ 8 root heart yearn circumferential array, every root heart yearn is made up of copper conductor and the insulation screen be arranged on outside copper conductor, and in heart yearn, at least one root heart yearn is as treating a point stand heart yearn, treats that point stand heart yearn has the branch's connection part be connected with branch cable;
Coating layer, it is arranged on outside described heart yearn, has internal shield from inside to outside, insulating barrier and outer shielding layer;
Obturator, it is arranged on the space place between coating layer and heart yearn;
Described branch cable has:
Branch cable copper conductor;
Insulating barrier screen, it is arranged on outside described branch cable copper conductor;
The branch cable copper conductor of described branch cable one end welds with the copper conductor silver-bearing copper at the connection part place of branch treating point stand heart yearn in main cable, and the outer circumference of branch's connection part arranges insulation screen structure.
Preferably: described insulation screen structure outer surface arranges reflecting coating band.
Preferably: all in the form of a ring, the thickness of described internal shield is greater than the thickness of outer shielding layer for described internal shield and outer shielding layer cross section.
Preferably: described branch cable copper conductor forms by 2 ~ 18 strands of copper wires are stranded.
Preferably: described copper wire is silver-gilt copper wire.
Preferably: described main cable surface arranges some spot-like projections.
Compared with prior art, the utility model has following beneficial effect: the utility model adopts silver-bearing copper to weld welding on the conductor of pre-branched cable joint, reduces resistance, improves the electric conductivity of joint.
Accompanying drawing explanation
Fig. 1 is pre-branched cable structural representation in embodiment.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1, a kind of pre-branched cable, comprises main cable 1 and branch cable 2.
Described main cable 1 has heart yearn, coating layer and obturator, heart yearn is formed by 2 ~ 8 root heart yearn circumferential array, every root heart yearn is made up of copper conductor and the insulation screen be arranged on outside copper conductor, in heart yearn, at least one root heart yearn is as treating a point stand heart yearn, treats that point stand heart yearn has the branch's connection part be connected with branch cable; Coating layer is arranged on outside described heart yearn, has internal shield from inside to outside, insulating barrier and outer shielding layer; Obturator is arranged on the space place between coating layer and heart yearn; Described branch cable 2 has branch cable copper conductor and is arranged on the insulating barrier screen outside described branch cable copper conductor.The branch cable copper conductor of described branch cable one end welds with the copper conductor silver-bearing copper at the connection part place of branch treating point stand heart yearn in main cable, and the outer circumference of branch's connection part arranges insulation screen structure 3.
Described insulation screen structure 3 outer surface arranges reflecting coating band 31, and on the whole, reflecting coating band 31 is arranged along main cable axis direction.The resolution of joint is improved in rather dark environment, can Timeliness coverage for the unexpected twisted phenomena produced, prevent joint failure.
All in the form of a ring, the thickness of described internal shield is greater than the thickness of outer shielding layer for described internal shield and outer shielding layer cross section.Described branch cable copper conductor forms by 2 ~ 18 strands of copper wires are stranded.Described copper wire is silver-gilt copper wire.
Described main cable surface arranges some spot-like projections (not shown).The effect of spot-like projections is anti-skidding and increases cable security.
The foregoing is only preferred implementation of the present utility model, protection range of the present utility model is not limited in above-mentioned execution mode, and every technical scheme belonging to the utility model principle all belongs to protection range of the present utility model.For a person skilled in the art, the some improvement carried out under the prerequisite not departing from principle of the present utility model, these improvement also should be considered as protection range of the present utility model.
