HIVOLT suspension insulators choose high quality materials for parts :
1 the insulator cap use high density ductile iron ,we test each pieces with magnetic powder inspection method . all the insulator pins made of forged steel .the bonded arec between zinc sleeve and pin are more than 85% , the zinc sleeve will offer a good protection of insulator pins , it can extended insulator working life .
metal fittings surface hop-dip galvanized , coating thickness meet IEC 60383 standard.
2 we manufacture ceramic parts with high aluminum porcelain C130 . the porcelain surface covered a layer of shinning glaze , color can be grey , brown or white , it depends on customer's requirement.
3 the cotter key made of stainless steel which guarantee insulator string connection locked firmly .
4 we use Portland cement code 525 # make the assembled insulator have very good mechanical performance and good plastic character during hot & cold temperature shift .
Applications:
the insulator can be used for tension string or suspension string in transmission lines , for example : 220KV,330KV, 400KV,500KV,750KV etc.
Or for substations.
Competitive Advantage:
we offer 2 years quality guarantee . high quality deserve your trust !
The porcelain glaze have a very good self-cleaning performance . it is easy for maintenance .
we offer very fast delivery , if the product are exactly same in stock , we can send it immediately .
We can design insulators based on customer’s requirement , so just let us know what you want , we will provide exactly product to meet your need.
