Technical Porcelain Power Line Insulators , Porcelain Electrical Insulators

porcelain core with silicone rubber shed railway support Insulators for railway systems , IEC standard

Description:

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 performance.

Applications:

the long rod insulator are very suitable for railway systems in electrical lines from voltage up to 66kV .

Competitive Advantage:

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.
