suspension insulators have below advanced charactors :
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 examplemetal cap withdensity ductile iron ,every pieces of cap aretested qualified with magnetic powdermethod .we producemetalpins with material of forged steel .
all the metal fittngs covered a layer ofhot-dipzinc 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 inpower lines 330KV, 400KV,500KV,750KV etc.
Competitive Advantage:
the HIVOLT insulator have very good mechanical & electricalcharacter , we offer2 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 relatedinsulators design . we called it a one-stop purchasing .
