ANSI 52-3 suspension insulators mainly used in the market of USA ,
Canada , and many South American countries .HIVOLT product export
to many of those countries , and have very good reputation just
because we use high quality materials for insulators :
1 the insulator cap use high density ductile iron ,we test each
piece of caps with magnetic powder testing method . the insulator
pins are made of forged steel .the material can guarantee the
inside of pin without any defects such as air , hole , crack etc.
Both cap and pin are hot galvanized , zinc thickness meet ASTM 135
2 we produce porcelain with high aluminum porcelain C120 . the
porcelain surface covered a layer of hard glaze , color can be grey
, brown or white or as per customer's specifications.
3 the material of R type locking pin is stainless steel which guarantee insulator
string connection very safety .
4 we use excellent Portland cement to assemble insulation body with
related cap and pins . even after years of servicing , the cement still keep good
insulator 52-3 are very suitable for tension string or suspension
string in electrical lines from 11kV up to 132kV in some
substations , you can also find it .
HIVOLT 52-3 insulators have a very reliable electrical &
machincal character .
the failure rate is lower than 1 per 100000 .
we offer 2years up to 4 years quality guarantee as per tender
requirement or customer's requirement .
The porcelain glaze are hard and shinning , it has very good
self-cleaning advantage . it is easy for maintenance .
We can design insulators based on customer’s requirement or special
