The electric field problem of composite insulators is mainly the electric field at its end. The electric field strength on the hardware is relatively large. In dry air conditions, corona may occur on the hardware. Therefore, it is necessary to find a way to reduce the electric field strength at the hardware end and install a voltage-equalizing ring to reduce the electric field strength at the hardware end.
