The series of product has derived the merit of the porcelain /glass insulator. The reliable pouring construction of connecting hardware fittings and porcelain core plate in the nose maintains the stable strength of mechanical tensile of the original porcelain insulator.

Because of the mould silicon rubber compound coat injected in the surface of the porcelain core plate, the insulator has a range of more excellent characteristic than porcelain insulator, such as waterproof performance, antiaging, strong ability of antipollution, light in weight. The ability of antipollution is 1.7 times as porcelain or glass insulators. The product passed the P. V. (Product Verification). Its technology is global patent and advanced. Moreover, it receives the national patent protection.
