Good Price High Voltage U160BLP 160KN Fog Type Anti-pollution Suspension Insulator Electrical Pylon Toughed Glass Disc Insulator

Glass insulator: it has good mechanical and electrical properties, and its tensile strength, electrical breakdown resistance, vibration fatigue resistance, arc burn resistance and cold and hot shock resistance are better than porcelain insulator. Different from porcelain insulators, glass insulators have the insulation self elimination ability of zero value self explosion, which is easy to be found without insulation test. The self explosion rate is usually higher in the first three years, which is opposite to that of porcelain insulators. Decades of operation and test data show that tempered glass insulators have long-term stable electromechanical properties and long service life. In order to obtain a large creepage distance, antifouling glass insulators can only be realized by adding several deep edges on the lower surface of the umbrella skirt (due to process reasons, it is impossible to increase the creepage distance through double umbrellas or three umbrellas like porcelain insulators). When used in areas with serious dust pollution, the umbrella type with deep edges of the bell cover has poor self-cleaning ability, inconvenient cleaning and serious scaling on the lower surface, resulting in greatly reduced pollution flashover resistance.
