Porcelain Rod Insulator

The porcelain rod insulator is of solid structure, and the cementing part adopts the cylinder sand structure. The sand used for the sand is special granulated sand which has been strictly controlled by the process, and has excellent bonding performance with the porcelain body and reasonable expansion coefficient, which can effectively improve the mechanical strength of the product.The flange structure of the product is reasonable, and the stress distribution is even.The material is ductile iron with high mechanical strength and hot dip galvanized surface.It has excellent resistance to corrosion.The cement used for glue installation is high grade cement, and the reasonable curing technology makes the strength of porcelain be fully exerted.Any voltage grade products are single column, with simple structure, long service life and less maintenance and other advantages.
