Polymer Suspension Insulator--Ball and Socker Insulator
① Shed connected with core by integral forming
② Metal end fittings, core and sheds connected by new crimping process
③ The thickness of housing > 3mm, uniform thickness, confirm to IEC Standard
④ Acid resistant, high temperature resistant of epoxy fiberglass core
⑤ The material of metal end fittings is used with hot galvanization and technology of rare earth aluminum
coating to avoid coating shedding when crimping, prolonging the service life of the product
