DXN12-3P High Voltage Live Line Indicator

The DXN12-3P high-voltage live display locking device is a device used for online detection of the live status of high-voltage cabinets or power grids and for implementing forced locking of the grounding knife switch on the live side. It can be used in places such as GIS combined electrical apparatus and high-voltage power grids.
