DMC Low Voltage Busbar Insulator With Low Voltage Switchgear
1. High intensity
2. Electrical resistance
3. Heat, fire, water resistance
4. Low shrinkage
The parameters are frequency dry, wet voltage, lightning shock voltage, lightning shock wave voltage, operation shock voltage. To avoid breakdown in operation, the breakdown voltage of the insulator is higher than the flashover voltage. In the factory test, the perforable ceramic insulator usually passes the spark test, that is, the high pressure makes the insulation surface produce the frequent spark, maintains a certain time, see whether the breakdown. Some insulators are also subject to Corona test, radio interference test, partial discharge test and dielectric loss test. At high altitude, the electrical strength of insulators decreases due to the decrease of air density, so the tolerance voltage should be increased when converted to standard atmospheric conditions. The flashover voltage of a dirty insulator when it is damped is much lower than its dry and wet flashover voltage .
