Description
Technical field
The present invention relates to a kind of multi-core branch cable.
Background technology
The multi-core power cable of existing prefabricated branch comes out in the known technology, but all is to make prefabricated branch joint on general, the common multi-core power cable.In the armoured power cable field, still there is not the armoured power cable of prefabricated branch joint at present.This be because: no matter be individual layer steel wire, double-layer wire, individual layer steel band, double-deck steel band, still the armoured power cable of other form will guarantee that all its armour does not have integrality disconnected, damage.So armoured power cable is made relatively difficulty of prefabricated branch cable.Yet, with common polyvinyl chloride insulation, pvc sheath; The prefabricated branch cable that the power cable of crosslinked polyetylene insulated, pvc sheath is made, under a lot of specific occasions or design drawing require to use in the environment of armoured power cable and all can't use.
Summary of the invention
The object of the present invention is to provide a kind of armored prefabricated multicore branch cable, can effectively solve the problem that existing armoured power cable can not prefabricated branch joint, make prefabricated branch cable under specific occasions or design drawing require to use in the environment of armoured power cable and can be applied.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of armored prefabricated multicore branch cable, it is characterized in that: comprise leader cable, leader cable armour, branch cable and branch cable armour in overall outer layer insulation sheath and the overall outer layer insulation sheath, leader cable and branch cable are crimped on by connector and form branch's connected body together, branch's connected body is provided with branch's connected body armour outward, and leader cable armour and branch cable armour are welded into an integral body by branch's connected body armour.
Further, moulding is sealed in the independent separately injection moulding of each phase place branch connected body.
Preferably, connector adopts U type branch joint connector.
Further, each phase place branch's connected body of independently sealing moulding separately keeps enough dislocation apart from S each other.
Further, leader cable comprises the leader cable conductor core wire, and leader cable conductor core wire outside is provided with separately independently leader cable primary insulation.
Further, injection mo(u)lding is sealed by leader cable outer layer insulation sheath in each leader cable primary insulation outside, and leader cable outer layer insulation sheath outside is provided with the leader cable armour.
Further, branch cable comprises the branch cable conductor core wire, and branch cable conductor core wire outside is provided with separately independently branch cable primary insulation.
Further, injection mo(u)lding is sealed by branch cable outer layer insulation sheath in each branch cable primary insulation outside, and branch cable outer layer insulation sheath outside is provided with the branch cable armour.
Further, branch's connected body is independently sealed integral solder leader cable armour after the moulding, branch cable armour and branch's connected body armour separately, seals injection mo(u)lding by main overall outer layer insulation sheath integral body again.
The present invention is owing to adopted technique scheme, the integrality and the continuity of armour have been guaranteed, comprise that the branch cable armour all is connected to an integral body reliably with the leader cable armour, the power cable that puts into operation all is being greatly enhanced aspect electrical characteristic, dielectric strength, watertightness, air-tightness, reliability, the consistency, make power cable under normal circumstances the operation troubles rate descend significantly, reach non-maintaining highly reliable running status.All branches and joint prefabricated finishing in specialized factory that this cable will need when paying the unit in charge of construction scene, site operation equipment is reduced, specification requirement reduces, expense descends significantly, time shortens in a large number, especially use the armoured power cable under anti-interference, radioresistance occasion, behind the Will armour reliable ground, improve whole anti-interference, the capability of resistance to radiation of whole system greatly.
