11kv pin type insulator is made from alumina porcelain, porcelain pin insulator used on overhead distribution lines with nominal voltage 11kv, and consisting of insulator porcelain parts and insulator pins.
The 11kv pin type insulators perform two basic functions: to provide mechanical support for the conductors, and to prevent passage of current to ground in clean or polluted area. A pin insulator is an insulator generally having means for rigid mounting on a separable pin.
