porcelain core with silicone rubber shed railway support Insulators
for railway systems , IEC standard
Product character :
the insulator core are made of high strength aluminum porcelain
C130 . It has both great mechanical and electrical performance .
normally such insulator surface will be injected a layer of
silicone rubber sheds .
the final product will be used for every high pollution area . this
special design can bring both hardness porcelain character and
silicone rubber higher level anti-pollution profile .
the product main used in coastal area , heavy rain area ,very high
pollution industrial zone etc.
the insulator cap use high density ductile iron ,we test each piece
of caps with magnetic powder testing method .
metal caps surface are hot galvanized , zinc thickness meet ASTM
135 standard .
we use excellent Portland cement to assemble insulation body with
related caps . even after years of servicing , the cement still keep good
the long rod insulator are very suitable for railway systems in
electrical lines from voltage up to 66kV .
have a very reliable electrical & machincal character .
the failure rate is lower than 1 per 100000 .
we offer 2years quality guarantee as per tender requirement or
customer's requirement .
the insulator are non-punctured type .
we can bond the silicone rubber sheath and sheds in our factory
based on customers requirement.
