AI Technical Summary
The screw holes of the existing ring main unit cable supports are too close to the cabinet body, which causes discharge phenomena. It is necessary to add additional insulating caps, which increases the cost of use.
Design a fully insulated ring main unit cable support, including an insulator, a conductive rod, a sensor coil, and an insulating plug. It is connected to the wiring copper busbar through a first connector and to the voltage sensor through a second connector. The insulating plug seals the free end, avoiding the need to install an additional insulating cap.
It eliminates the need for additional insulation caps, improves the safety of cable supports, reduces the cost of ring main units, and features a simple structure and easy installation.
