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'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 .
