The polymer pin insulator consists of a core rod, a silicone umbrella and a metal fitting.Pin insulators have high resistance to bending, shock, shock and explosion.With reliable internal insulation and light weight, it is an ideal replacement for the traditional tempered glass insulator.
       The silicone rubber shed adopts the all-envelop pressure technology to solve the key problem that affects the reliability of composite insulators -- interface spark breakdown.
Pin insulators have high strength, beautiful appearance, small size and light weight, and the metal parts electroplated can prevent corrosion and exchange with porcelain insulators.
      The product has reliable structure, no damage to the mandrel, and makes full use of mechanical strength.
