33kv High Voltage Electrical Ceramic P-33-Y/825 Pin Insulator with Spindle
QOCI ELECTRIC - P-33-Y is a pin-type insulator commonly used in distribution lines. It is mainly used in medium voltage transmission lines such as 33kV to support and insulate conductors to prevent current backflow to pole towers or other grounded structures.Product Features:Head groove: Used to secure conductors, often used with wire ties.Center hole: Used to install a threaded metal pin for connecting to crossarms.Shell design: Improves creepage distance and pollution resistance.Strong electrical insulation: Suitable for outdoor lines in harsh weather conditions.
