HIVOLT ceramic disc insulators use below materials for parts :

1 the insulator cap are high density ductile iron ,we test each pieces with magnetic powder inspection method . all the insulator pins made of forged steel with diameter 32mm .

metal fittings surface hop-dip galvanized , coating thickness meet IEC60383 standard.

2 ceramic shell are made of high 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 we tested every unit of insulators by routine test , it including :

​ a) routine tension load strength test , which will apply 50% of rate mechanical strength

withstand 1 minutes .

b) routine flashover test , will check every piece of insulators with high voltage flashover,

to sort defect unit out.

4 we will test each batch of insulators by sample test , which including :

insulator visual check ,overall dimensional check , temperature cycle test , mechanical and electrical failing load test , puncture test , metal fitting zinc thickness thickness test etc.


the U530B product are Suitable for tension string or suspension string in power lines 500KV, 750KV and 1000kV etc. this type of product are in huge quantity used and accepted by National Utility .

Competitive Advantage:

U530B ceramic disc insulator has perfect mechanical & electrical character , so we can offer 2 years quality guarantee period . after several years running , the data shown the insulator failure rate are less than 1 per 100000 .

we also guarantee every units of insulators are well tested and without any defect before ship out of factory .
