Station Post Insulators
Station Post Insulators
We supply high quality station post insulators according to IEC ,ANSI standards or customers' specifications .
IEC standard products including : C8-550 , C8-1050 , C10-1175, C12.5-1800 etc.
ANSI standard post insulators including: TR202, TR205, TR208,TR216, TR286, TR304 ,TR295 etc.
The station post insulator can be made up to 1000KV , 30KN .
The shapping method in both Isostatic pressing and wet process are all available .
HIVOLT station post insulators choose high quality materials :
- 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 .
- 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 .
- Cement : excellent Portland cement make the assembled insulator have very good mechanical performance and the quality are more reliable .
- 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.
