Embodiment Construction

[0015] Such as figure 1 As shown, a kind of pre-branch cable according to the present invention includes a trunk cable 1, a branch cable 2, a connector 3, and a branch sheath 4. The trunk cable 1 and the branch cable 2 are connected together through a connector 3, and the trunk The branch sheath 4 is covered at the branch joint of the cable 1 and the branch cable 2 .

[0016] The above-mentioned trunk cable 1 is a single-core, multi-core or twisted multi-core cable, the twisting direction is left, and there is no intermediate joint in the vertical direction; the branch cable is a single-core cable; the branch protection The sheath is PVC molded insulation, and its thickness is not less than the sum of the trunk cable insulation thickness plus the sheath thickness.

[0017] The present invention provides a pre-branched cable structure and implementation method. The above is only a preferred implementation method of the present invention. It should be pointed out that for those...

Abstract

The invention discloses a pre-fabricated branch cable. The cable comprises a main cable, a service-main cable, a connecting part and a branch sheath, wherein the main cable and the service-main cable are connected with each other through the connecting part, and the branch sheath is wrapped in the joint position of the main cable and the service-main cable. The branch cable provided by the invention has convenience in on-site construction and an excellent insulated, waterproof and fire-resistant property.

Description

[0001] technical field [0002] The invention relates to the field of power cables, in particular to a pre-branched cable. Background technique [0003] With the strong growth of our country's national economy, various infrastructures, basic constructions, and real estate development speed up, it is inevitable to use power cables as the main supply lines in various buildings and facilities. Therefore, construction units, design units, and construction units are all seeking more advanced, more economical, superior performance, smaller effective space occupation, and shorter construction period power supply and distribution construction technologies and methods. It is also under such historical environmental conditions that pre-branch cables have made great strides into my country's architectural electrical stage. [0004] The pre-branch cable, as the name suggests, is to split multiple cables from the main cable, that is, the branch cable. It is characterized in that the mai...
