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  each piece of insulators are routine tested , test items including:

​ routine tension load strength test , which will apply 50% of rate mechanical strength withstand 1 minutes . after this test , we conduct 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 with sample test ,  including below items:
 
dimensional check , temperature cycle test , M&E failing load test , puncture test , galvanization thickness test  , porosity test etc.  if customer required , type test also available .
 
for example steep front wave test , Thermal mechanical test etc .
 
 
 
 

Applications:

the U210BWP3 product are Suitable for suspension string in power lines 330KV, 400KV,500KV etc.

 

 

Competitive Advantage:

the HIVOLT insulator U210BWP3 have very good M & E performance , we offer 2 years quality guarantee .

every units of insulators are tested qualified , to guarantee all insulators are without any defect.

if customer can provide technial data , We will make related insulators design . ​OEM product are available .
