RM and Other Type Insulators

Voltage:0.4-36kV
BONLE manufactures a wide range of low and high voltage Pin Type insulators designed for distribution systems, highly resistant to lightning puncture Pin insulators of one piece or multi-piece construction are widely used in low cost distribution lines. Multi-piece construction makes these insulators less vulnerable to damage as with one shell broken a multi-piece insulator can normally withstand the line voltage for a considerable time without difficulty.
As the name suggests, the pin insulator is secured to the cross-arm on the pole. There is a groove on the top of the insulator to hold the conductor. The conductor passes through groove and is bound by the same material as the conductor.
