The glass insulator consists of cast-iron cap,toughened glass body and pin,which are agglutinated together by cement into an intergrated piece.Cylindrical head has been adopted for products,which is the most advanced structure in the world with superiorities such as less dimension, lighter weight, higer strength and longer creepage distance which can save metallic materials and reduce transmission line cost. In order to adapt hot line operation, the traditional structure shape has been adopted for on the edge of cap. The products with the cylindrical head are most widely used in the world. We have accumulated a wealth of prarical experiences for their oprations.The products applied on the high voltage,ultra-high voltage and DC for insulation and suspension.

-Zero spontaneous breakage and easy inspection -Excellent arc-resistance and Vibration-Proof performance -Good Self Cleaning and Less Age -Large Main Electric capacitance, homogenous distribution of voltage on single string insulators
