Embodiment Construction

[0016] The present invention will be further elaborated below according to the drawings and specific embodiments.

[0017] like figure 1 and figure 2 Shown, a kind of method of making low-voltage branch cable head on the spot of the present invention comprises the following steps: one, remove insulation sheath: remove insulation sheath 12,32 at main cable 1 needs branch and the end of branch cable 3; Two, Connect the main cable 1 and the branch cable 3 at the joint: use the branch C-shaped connection clamp 4 to crimp and fix the main cable 1 and the branch cable 3 at the joint; Two separate PVC injection-molded branch covers 5 are covered, and the joints 51 of the two branch covers 5 are fixed by screws; 4. The mixture 8 of room temperature vulcanized silicone rubber on-site and coupling agent is matched with a pressure injection tool Inject into the mold cavity that is made up of two branch covers 5 through the injection port 52 on the branch cover 5, and form insulation a...

Abstract

The invention relates to a method for on-site manufacturing a low-voltage branch cable head, which comprises the following steps: 1, removing an insulating sheath, namely, removing the insulating sheath at a main cable needing branching and on the end part of a branch cable; 2, connecting the main cable and the branch cable at a joint, namely, fixing the main cable and the branch cable at the joint by a branch connecting clamp in a compression joint way; 3, covering the main cable and the branch cable at the joint through two separable branch covers and fixing the two branch covers; 4, injecting the mixture of room-temperature vulcanized silicone rubber and a coupling agent which are matched on site into a cavity consisting of the two branch covers with a die-casting tool and forming insulation at the branch joint; and 5, sealing an injection port. The method of the invention has the advantages of not only improving the tensile resistance of the cable head, but also improving the moisture resistance, corrosion resistance, tightness and operational reliability and safety of the cable head.

Description

technical field [0001] The invention relates to a method for making a cable head, in particular to a method for making a low-voltage branch cable head. Background technique [0002] Branch cables are used in high-rise buildings, factories, commercial buildings, supermarkets, squares and other power and lighting transmission and distribution lines of 0.6 / 1kV and below. High-standard branch cables are basically prefabricated in the factory. The dimensions of the main cable, branch cables and branch connections must be measured before production. However, deviations will occur during the actual engineering installation process. For prefabricated branch cables The position of the branch cannot be changed, and it cannot well meet the needs of the actual branch head position during installation, which is not conducive to the positioning requirements of the branch head. [0003] In addition, in the factory production of prefabricated branch cables, the designed length of the branc...
