Upper Metal Cap Of Insulator

In power transmission and distribution systems, component polymer suspension insulator is constructed from ceramic, glass, or composite materials, and its top is typically fitted with a metal cap for connection and fixation. The metal cap, as a crucial component of the connecting hardware, enables component suspension type insulator to fit tightly with conductors, suspension rods, or other supporting structures.

The metal cap structure design includes the cap body itself and a locking assembly. The locking assembly can consist of threaded pins, inner and outer locking plates, and positioning nuts to achieve a secure connection and positioning. Through this structural design, the metal cap, after mating with the insulator end, can withstand mechanical and electrical loads, maintaining the stability and reliability of the overall component composite tension insulator.
