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.
