HIVOLT suspension insulators choose high quality materials for parts :
1the 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 manufactureceramic parts withhigh 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 usePortland 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 offer2 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 customers requirement , so just let us know what you want , we will provide exactly product to meet your need.
