suspension insulators have below advanced charactors :
?
1? the insulation part use high aluminum porcelain C130 , glaze color grey , brown or white?,or customer& acute;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.
