Description
AC Non-Gap Metal Oxide Lightning Arrester, which is used to protect the insulation of ac power transmission and transformation equipment from lightning overvoltage and operation overvoltage damage. It is suitable for overvoltage protection of transformers, transmission lines, power distribution panels, switch cabinets, power metering boxes, vacuum switches, parallel compensation capacitors, rotating motors and semiconductor devices.
Normal Condition Of Use:
1)AC system frequency is 50Hz or 60Hz.
2)The ambient air temperatures is no higher than +40° C, no lower than-40° C.
3)The altitude above sea level does not exceed 2000m.
4)Maximum wind speed does not exceed 35m/s.
5)The earthquake intensity does not exceed 7 degrees.
6)AC voltage brought to bear on arrester for a long time does not exceed arrester’s continuous operating voltage.
