Porcelain Horizontal Mounting line Post Insulators
This series of Horizontal Mounting line post insulators are rating from 25kV to 230kV . Their cantilever strength are usuallly 2800lbs(12.5kN). but they can also achieve a cantilever strength to 3500lbs or 4000lbs when they are 138kV or 220kV. They have a mounting base at the bottom designing for attachment to pole gains or brackets for mounting to steel poles or concrete or steel structure.There is also a metal cap at the top of the insulator,which is for supporting the trunnion type clamp. This Clamps are for conductors sizes from 0.25″ to 2.70″
