Abstract

The invention discloses a prefabricated multi-core coaxial branch cable which comprises an overall outer layered insulating sheath, and a main cable and a branch cable arranged in the overall outer layered insulating sheath; the main cable and the branch cable are in compression joint through a connecting piece to form a branch connecting body; all phase branch connecting bodies are in respective and independent injection molding, sealed and formed; a U-shaped branch connector connecting body is adopted as the connecting piece; and enough dislocation space S is kept among the branch connecting bodies with the phases respectively and independently sealed and formed. By adopting the technical scheme, the power cable which is put into operation is greatly improved in electrical properties, insulating strength, water tightness, air tightness, reliability and consistency, so that the operation fault rate of the power cable is greatly reduced under normal circumstances, and achieves the maintenance-free and high-reliability operation status. All branches and connectors of the cable are prefabricated in a professional factory, so that the number of on-site construction equipment is reduced, the technical requirements are lower, the cost is greatly reduced, and the time is largely shortened.

Description

technical field [0001] The invention relates to a multi-core coaxial branch cable. Background technique [0002] The processing of power cable branches and joints in the known technology is generally at the cable laying construction site, cut and peel off a section of cable outer sheath and memory insulation at the specific branch or joint position, and then use U-shaped connectors to pass through. Tools such as hydraulic pliers crimp the two cable conductors after the sheath is stripped and insulated, and finally use epoxy resin or other insulating materials for insulation encapsulation. Its flaws are: [0003] 1. Difficult to guarantee insulation strength, poor reliability and consistency; [0004] 2. The construction site occupies a large space; the technical requirements are high; the cycle time is long; the cost is high. [0005] Although there are also invention patents (such as: CN2411542Y) and invention patents (such as: CN1308343A) of prefabricated multi-core bra...
