Product description
Insulator pin spindle, made of hot-dip galvanized steel to withstand corrosion and rust caused by exposure to weather conditions. It is used to support and secure pin-type insulators on power transmission and distribution towers and structures. The spindle prevents the flow of electrical current from the conductor to the tower body, ensuring network safety and preventing accidents. The threaded top part is designed to hold the pin-type insulator, while the lower part is designed for mounting onto the tower or structure.
