11kv pin type insulator

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.

11kv pin type insulator

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.

Service conditions of 11kv pin type insulator
Maximum altitude: up to 1000m
Maximum ambient temperature: 50 ℃
Minimum ambient temperature: -10 ℃
Average ambient temperature for year: 30 ℃
Maximum relative humidity: 10%
