How to connect the power cable pre-branch connector
Pre-branch cable detection: a In addition to routine pressure test, it is necessary to increase the insulation resistance test, with a shake table can be completed in each branch after the completion of injection The table measures the insulation in the finished product After the pressure is also used to detect the insulation of the table to prevent the water cooling process in the branch of the water caused by short-circuit, the general AC voltage test can not detect, can only increase a set of table detection process B Core conduction detection, In each branch body should be tested with the trunk of the conduction test to prevent the production process due to improper operation caused by the branch and the trunk circuit
In the pre-measured size cut out the jacket and insulation, according to the different cross-sectional size of the cable cut the size of the jacket and insulation different; with C-shaped tube corresponding to the corresponding color sequence crushing the trunk and branch lines, crimping attention to crimping The strength of the clamp, can not be too loose or too tight, too loose will cause the cable crimping off, resulting in open circuit, crimping too tight will break the conductor or cause the conductor stranded in the contact with a good conductor with polytetrafluoroethylene With the winding baking transparent, and then wrapped waterproof tape (tiger belt) can be used after the wooden hammer shrink the cable core to facilitate injection molding in the injection process should choose the appropriate mold and injection molding machine injection mold injection, the mold is too large cost Waste, the mold is too small caused by defective, bad seal at both ends of the running coke, affecting the injection effect
Pre-branch cable should be fully cooled before the plate can be installed, otherwise it will cause the connection flat, affecting the appearance of packaging should pay attention to branch and trunk The end of the seal, to prevent the core of the water
