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 .
Applications:
the U300BWP3 product are Suitable for suspension string in power lines 330KV, 400KV,500KV,750KV ,1000KV 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 !
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 .
