HIVOLT suspension insulators choose high quality materials for
1 Cap & Pin the cap use high density ductile iron ,every pieces
tested qualified after magnetic powder inspection . the pins are
made of forged steel .Both cap and pin are hot galvanized , zinc
thickness meet related IEC and ASTM standard requirement
2 Porcelain the insulation part use high aluminum porcelain C120.
the porcelain surface covered a layer of shinning glaze , color can
be grey , brown or white
3 locking device material stainless steel which guarantee insulator
string connection very safety .
4 Cement excellent Portland cement make the assembled insulator
have very good mechanical performance and the quality more reliable
the 52-5 fog type disc insulator is suitable for tension string or
suspension string in power lines from 132kV up to 330KV .
especially in heavy pollution area , for example : coastal area ,
heavy rain area , heavy industrial zone etc.It can also be used for
each piece of insulator are routine tested and sample tested before
so we guarantee each batch of insulators have qualified mechanical
& electrical performance , we offer 3 years up to 5 years
quality guarantee based on different customer's requirement .
after a long time data seraching , our insulator failure rate is
lower than 1 per 100000 .
we can say the quality is our life . we look at it as firm base for
developing more business .
