The GSR environmentally friendly smart gas-insulated ring main unit is a green intelligent switchgear introduced based on mature German eco-friendly smart design concepts. This series of products uses dry gas as the insulating medium, enclosing the primary main circuit of the switchgear in a gas chamber welded by robots and rigorously leak-tested with helium mass spectrometry. It employs a mature and reliable vacuum arc extinguishing chamber as the main switching element for the vacuum circuit breaker and load switch, and uses a specially designed three-position isolating switch to ensure safe and reliable operation and maintenance of the distribution network.
The launch of the GSR series environmentally friendly smart fully enclosed switchgear genuinely meets the needs of clients such as the State Grid and China Southern Power Grid for eco-friendly ring main units, and represents the future development trend of environmentally friendly ring main unit products.

环保概念
环保智能全封闭开关设备采用新技术使用氮气防护或干燥空气作为绝缘介质。GSR系列开关设备将不再采用受限制的SF6气体，在气箱内充氮气并采用微正压的技术，主要目的为防止潮气的入侵对气箱内绝缘的影响，设备使用寿命周期内无需进行气体回收处理。开关主体部件采用可回收处理金属材料，大大降低设备使用到期后对环境的影响。是真正环保型的环网柜产品，满足电网客户对环保设备的需求。使用环保可回收材料，产品寿命周期后减少对环境造成影响。真正实现环保无害化功效。
