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 metal cap are made of density ductile iron ,every pieces of cap are tested qualified with magnetic powder
method . metal pins are made of forged steel .
all the metal fittngs covered a layer of hot-dip zinc coating .
3 the insulator shape are special , it is triple sheds , this kind
of design can provide excellent electrical performance than normal
fog type insulators ,
and if the service area with strong wind , this type of design can
decrease wind force and keep the transmission line safe .
4 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.
5 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
the U300BWP3 product are Suitable for suspension string in power
lines 330KV, 400KV,500KV,750KV ,1000KV etc.
the HIVOLT insulator have very good mechanical & electrical
character , we offer 2 years quality guarantee . we believe high
quality deserve your trust !
every units 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 .
