L70BE380 supension long rod insulator mainly used in the market of EU countries .HIVOLT product sold to many of them . we have good reputation among customers due to high quality .

1  the insulator cap use high density ductile iron ,we test each piece of caps with magnetic powder testing method .

The insulator cap surface are hot galvanized , zinc thickness meet related IEC standard .

that is Min. zinc thickness are more than 85μm . the galvanization surface are smooth and shinning , and free of defect.

2  The insulation parts are made of high aluminum porcelain C130 . the porcelain surface covered a layer of hard glaze , color brown , we can also produce such product with color white , grey or as per customer's specifications.

3  the material of  R -clip  is stainless steel which guarantee insulator string connection very safety .

4  we use  excellent Portland cement to assemble porcelain body and related cap .    even after years of servicing , the cement still keep good performance.


L40BE200 supension long rod insulator are suitable for tension string or suspension string in transmission or distribution lines from 11kV , 25kV or 33kV .

Competitive Advantage:

L40BE200 supension long rod insulator have a very reliable electrical & machincal character .

the failure rate is lower than 1 per 100000 . 

we offer 3 years quality guarantee period , if the product has inside defect , we will replace it free of charge .

The porcelain glaze are hard and shinning , it has very good self-cleaning advantage . it is easy for maintenance .

the insulator are non-punctured product . so the transmission line maintainese will be much more easier
