The most fundamental requirement for cable connectors is to have sufficient insulation, mechanical and sealing strength. The insulating tape used to make the cable joint must have sufficient mechanical strength. Other insulating materials should also have low water absorption, low gas permeability and dielectric loss tangent, good electrical stability, and should not be used to accelerate aging and A material that reduces the strength of the insulation.
The basic technical requirement for making cable joints is to carefully clean and dry all insulating materials, and carefully protect the original core insulation at the three-pronged end of the cable core from damage; the wound-insulating tape should be tightly packed tightly to ensure interlayer No gaps, strict control of the proportion of cable glue (including epoxy resin compound) and watering temperature.
The structure of the cable connector must be simple, compact, lightweight and easy to construct on site.
