POST SILICONE INSULATOR

 

Post silicone insulators are used for middle voltage non-insulated aerial networks from 10 kV to 35 kV. They are made according to IEC 61109 standards. They are standardly produced with steel bolts M24/140 mm, and at customers demand we can make them with steel bolts from M20 to M36, with different lengths from 40mm to 200mm. Corrosion protection is achieved with hot dip galvanization.
