Physical dimension
Environmentally friendly gas-insulated metal enclosed switchgear is the most commonly used three-phase intelligent gas-insulated AC cabinet and is widely used in various switchgear sets, with population concentration in the country, the power market must be supported, environmentally friendly gas-insulated switchgear will also grow with market development; market potential is yet to be tapped. At the same time, as the product integrates data collection and management, data processing and storage, online monitoring of switchgear, advanced analysis, and other multifunctions in one, network intelligent monitoring and management of the distribution network, so that the distribution network operates in a safe, reliable, high-quality, and efficient best state, to achieve remote monitoring, management, and control of the power system distribution network, to achieve network optimization, safe electricity use, power management, energy saving, and consumption reduction; at the same time, the system can be widely used in intelligent power distribution fields such as transportation, factories, hospitals, schools, buildings, residential areas, and commercial office buildings.
