Product characteristics
1. Porcelain sheath use high strength electrical porcelain with high mechanical strength, good stability, excellent weather resistance, corrosion resistance and anti electrical erosion ability, especially suitable for coastal salt fog area and harsh natural environment .
2. Porcelain sheath use the structure of rainshed with alternated sizes and reasonable climbing distance design ,which is with good anti pollution flashover performance and easy for cleaning a n d maintenance.
3. Multiple sealing design structure, so it is with very good sealability, which will prevent from inundation and oil leakage while operating.
4. Prefabricated stress cone is made of imported liquid silicone rubber, so it
Is with better electrical properties.
5. AII the prefabricated stress cones are 1 0 0 % inspected according to the standard before leaving the factory.
