The steel cap of terminal fittings of pin insulators is an important part of pin insulators.

I. Function

1. Connecting function: The steel cap is used to connect pin insulators with other power equipment such as conductors and crossarms. It provides a reliable connection point to ensure the stable operation of the power system.

   
   

2. Fixing function: Firmly fix the insulator at the installation position to prevent it from moving or falling off under the action of external forces such as wind force and gravity.

   3. Protective function: Protect the end of the insulator and reduce the damage to the insulator from the external environment.
