HIVOLT station post insulators choose high quality materials :

1, Metal flange :  We use high density ductile iron or malleable iron ,every piece are tested qualified with magnetic powder inspection .

Flange surface are hot dip 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 are 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 ,  after the treatment , the insulators can be used in extra heavy pollution area.
