1. the left side copper shell improvements structure that crosslinked cable joint is used, is characterized in that:

  • include interior copper pipe, outer copper pipe and be arranged at the insulating barrier of interior copper pipe outer surface and outer copper pipe surfaces externally and internally;

    Described insulating barrier is structure as a whole;

    The external diameter of described interior copper pipe is less than the internal diameter of outer copper pipe, one end of interior copper pipe and one end of outer copper pipe be fixedly connected with by insulating barrier but in copper pipe with outer copper pipe without being electrically connected;

    The wall thickness of described outer copper pipe is greater than the wall thickness of interior copper;

    Be set to throat structure at interior copper pipe away from one end of outer copper pipe, by an external diameter be less than the copper pipe of interior copper pipe internal diameter and connect in the connecting copper pipe of copper pipe and copper pipe form;

    One end of described interior copper pipe extend into the middle part of outer copper pipe, the axial cross section that is arranged at the left side copper shell of the insulating barrier between interior copper pipe outer surface and outer copper pipe inner surface is U-shaped, and the thickness that is wherein positioned at the insulating barrier of copper pipe outer surface reduces to extreme direction gradually from U-shaped bottom;

    On the copper shell of left side, be provided with two grounding legs, one end of two grounding legs is connected with outer copper pipe with interior copper pipe respectively, and the other end is for connecting with earth connection.
