Overhead Line Accessories High Voltage Suspension Toughened Glass Insulator Disc XP XHP Suspension Type Insulator for Power Distribution Equipment

Glass insulator, also known  as disc-type suspension insulator, is used for insulation and fixing wires in AC overhead power lines, substations and electrified railway catenary lines with rated voltage above 1000V and frequency not exceeding 100Hz. Because of its structural characteristics, the disc insulator has obtained superior mechanical and electrical strength, in addition, through the serial connection of components, can obtain any voltage level of the insulator string, so it is widely used in high voltage, ultra high voltage and ultra high voltage line, is an important line insulator. Start calculation glass insulators are generally connected in series, so the insulator element does not have a certain rated voltage, and according to the electromechanical damage load is divided into 40, 70, 100, 120, 160, 210, 240, 300, 420(400), 550(530) grades. Glass disc-shaped suspended porcelain insulators are made of iron caps, insulating parts (porcelain parts) and steel feet glued with cement cement, which can be divided into ball and socket connection and trough connection according to the requirements of use. There are three main types of disk-type suspended porcelain insulator shapes: ordinary type, bell jar type and aerodynamic type, aerodynamic type is divided into single umbrella, double umbrella and three umbrella.
