Description:

?

HIVOLT suspension insulators choose high quality materials for parts :

?

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 .

?

?

Applications:

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 substations.

?

?

Competitive Advantage:

each piece of insulator are routine tested and sample tested before delivery .

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& acute;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 .
