550kV Station Post Insulators With IEC60168 / IEC60273 Standard

Description:

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.

Applications:

Suitable for substations and electrical switch up to 1000KV etc. The insulator can be used as vertical or inverted .

Competitive Advantage:

High aluminum porcelain C-130 , the insulator core diameter are smaller ,while the mechanical strength are in high level . compare with other supplier’s product , we decrease much the unit weight . it is more suitable for insulator assembly in lines , and make easier maintenance. The actual cantilever strength are more than 50% higher than rated value .

we offer 3 years up to 5 years quality guarantee .

The porcelain glaze are smooth and shinning , have a very good self-cleaning performance . it is easy for maintenance .

OEM design available upon customer’s requirement or special technical specifications.
