suspension insulators have below advanced characters :
1 the insulation part use high aluminum porcelain C130 , glaze color grey , brown or white ,or customer's specification .
2 we produce metal fittings for example metal cap with density ductile iron ,every pieces of cap are tested qualified with magnetic powder method . we produce metal pins with material of forged steel .
all the metal fittngs covered a layer of hot-dip zinc coating .
3 we tested each piece of insulators by routine test , test items shown below :
routine tension load strength test , which will apply 50% of rate mechanical strength withstand 1 minutes .
routine flashover test , will check each piece of insulators one by one , to sort defect unit out.
4 we will test each batch of insulators by sample test , the test items including :
visual and dimensional check , temperature cycle test , M&E failing load test , puncture test , galvanization thickness test etc.
Applications:
the U300B product are suitable for tension string or suspension string in power lines 330KV, 400KV,500KV,750KV etc.
Competitive Advantage:
the HIVOLT insulator have very good mechanical & electrical character , we offer 2 years quality guarantee . we believe high quality deserve your trust !
each pieces of insulators are well tested , to be sure all insulators are without any defect.
if customer can provide technial data , We will make related insulators design . we called it a one-stop purchasing .
