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 .
Applications:
H4-125 support post insulator are used for electrical switches or electrical cabinet as insulation parts ,
also it have very good mechanical performance.
Competitive Advantage:
We manufacture such type insulators with high aluminum porcelain C-130 , the product mechanical strength are in high level . The actual cantilever strength are more than 50% higher than rated value .
we offer 3 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.
