Composite Dried Wall Bushing
'
Technical Advantage
The wall – bushing acts as the electric insulator and machinery support of high – pressure conductor when it crosses walls or other earthing matters Between major insulator and capacitance screen, major insulator and outer insulator it is really dried. It is new environment protection product with many advantages such as oil free, magnetism free, anti-dust, burst-proof, small volume and easy maintenance and so on.
