HIVOLT station post insulators choose high quality materials :
1 Metal flange the flange use high density ductile iron or malleable iron ,every pieces test qualified after magnetic powder inspection .
Flange surface are hot galvanized , zinc thickness meet related IEC and ASTM standard requirement
2 Porcelain the insulation part use high aluminum porcelain C130 , the porcelain surface covered a layer of hard and shinning glaze , color can be grey , brown or white .
3 Cement excellent Portland cement make the assembled insulator have very good mechanical performance and the quality more reliable .
4 silicone sealant we sue a layer of silicone sealant cover the cement ring surface , just to protect cement have a stable performance for longer life ,
In the meantime , it can prevent cement dust fall down to pollute the electrical instrument .
one more thing , we can also paint HRTV on the insulator body surface , if customer has such requirement .
the HRTV coating has excellent insulation performance , it can be used in extra heavy pollution area.
