Abstract
The utility model relates to the improvement to the power transmission cable, in particular to a preformed branch cable which has the ability of resisting the electromagnetic interference, which is characterized in that a metal shielding layer is arranged on the outer of the conductor insulation cocoon of a main cable and a branch cable, an outer cocoon is arranged on the outer of a shielding layer, the metal shielding layers of the main and the branch cables are electrically connected into a whole at a branch joint by a metal wire with the insulating layer. As the utility model better solves the mutual electrical connection of the metal shielding layer at the branch joint, disconnecting metal shielding layers are connected into a whole, the shielding effect is effectively guaranteed, a branch cable with shielding is supplied for the occasion needing the shielding.
Description
Technical field
Utility model is about the improvement to the electric power handling cable, relates in particular to a kind of prefabricated branch cable with anti-electromagnetic interference capability.
Background technology
Prefabricated branch cable be a kind of factory according to the cable user requirement, with the branching type cable of a kind of trunk branch tree structure of leader cable, branch cable and the prefabricated composition of insulating protection overcoat, disclosed in factory as Chinese patent 02208966 etc.Yet in various electrical equipment, instrument, telecommunications, power equipment and automation equipment occasion and transmission line, anti-interference requirement is often arranged, require to reduce the interference of external electromagnetic field on the one hand, also must reduce the electromagnetic field influence to external world that electric current produces in the electric wire simultaneously electric current in the electric wire.Yet because the needs of branch, cable is cut in the bifurcation insulation, and conductor exposes, and its insulation is behind the branch joint that completes, at joint integral coating insulation oversheath.Because the joint conductor exposes, this just makes and is difficult to resemble that easy processing is provided with metal screen layer the common cable, especially multi-core branch cable, joint is more complicated, many conductors are all exposed, therefore, existing branch cable is difficult to install additional metallic shield, and forms the prefabricated branch cable of band shielding.
Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, and a kind of metal screen layer that has is provided, and can effectively weaken inner and outer magnetic field and disturb, and the easy prefabricated branch cable of processing and fabricating.
The utility model purpose realizes, main cable and branch cable that main improvement is a branch cable all are provided with metal screen layer, and at the metal screen layer of branch's connecting section with the plain conductor connection stripping section of tape insulation layer, the metal screen layer electrical connection of stripping section is integral, thereby forms complete screen.Specifically, the utility model prefabricated branch cable, comprise main cable, some branch cables and branch's connector, it is characterized in that said main cable and branch cable conductor insulation sheath have metal screen layer outward, screen has outer jacket outward, and said master, branch cable metal screen layer are integral by the plain conductor electrical connection of tape insulation layer at the branch joint place.
The said cable of utility model can be single-core cable as required, also can be multicore cable; The metal screen layer of said main cable and branch cable according to instructions for use, can be the wrapped or vertical bag of copper strips, aluminium foil is wrapped or vertical bag (embossing), copper wire winding, copper wire braiding etc.; Said metal screen layer can be one deck, also can by above-mentioned several metal screen layers form two layers or more than.The electrical connection of stripping section metal screen layer, a kind of comparatively plain mode, be plain conductor with the tape insulation layer by being welded to connect, for helping processing and fabricating, said plain conductor is advisable with insulated copper core cord especially.
The utility model prefabricated branch cable, by metal screen layer is set in cable, and with the plain conductor of tape insulation layer the metal screen layer of main cable and branch cable is formed and to be electrically connected, the metal screen layer that each is disconnected connects into complete screen, effectively guaranteed shield effectiveness, solved the difficult technical barrier that metal screen layer is set of branch cable preferably, branch cable can be satisfied has the requirement occasion to use to shielding.Reach and both can reduce the interference of external electromagnetic field, also reduce the electromagnetic field influence of electrical equipment to external world that electric current produces in the electric wire simultaneously electric current in the electric wire.
