NXAirS-LP
Metal-enclosed medium-voltage switchgear
The DLHM-12 environmental protection type outdoor high-voltage energy metering box is developed to meet the needs of the power system. It perfectly combines the ownership boundary point and the metering point, and is a metering device with an intelligent switch function. The product shell is made of stainless steel and is treated with anti-sticking spray coating. The protection level reaches IP44. According to different functions, it is divided into four independent compartments: high-voltage switch room, metering room, inlet room and outlet room. The vacuum circuit breaker and metering current transformer adopt a fully sealed and fully insulated structure, with strong weather resistance and safety. During use, the metering CT can be selected from 5/5A-600/5A to meet the needs of different customer loads.

- Product Features
●Mechanical Dynamic Position Indicator
●The mechanical dynamic position indicator can separately display the ON/OFF status of the isolator and ground switch.
●The operating handle jack and control elements are clearly arranged next to the controlled switch or ON/OFF indicator.
●All switch operations can only be performed when the high-voltage room door is closed.
●The installation height of all components meets ergonomic requirements.
●Optional: Capacitive live display device used to detect whether the feeder or busbar is energized
