L40BE200 supension long rod insulator mainly used in the market of EU countries .HIVOLT product export to many of those countries , and have very good reputation just because we use high quality materials for insulators :
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.
Applications:
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 .
