Product Description

Environmental Friendly Gas insulated Metal Enclosed Switchgear

Keeya, a leading supplier based in China, offers state-of-the-art and Environmental Friendly Gas insulated Metal Enclosed Switchgear solutions. The Air12 series environmentally friendly gas insulated metal enclosed switchgear adopts a vacuum arc extinguishing chamber for arc extinguishing, with environmentally friendly gas as the main insulation medium, a small amount of solid insulation support, and the main circuit Without any encapsulation, it is at zero gauge pressure or slightly positive pressure during normal operation (the pressure of the air box is 0.02MPa), and the insulation capacity between phases meets the air insulation requirement at zero gauge pressure.

Environmentally friendly gas insulated metal enclosed switchgear is a commonly used three-phase AC intelligent environmentally-friendly gas insulated cabinet, and is widely used in various complete sets of switchgear. With the concentration of the domestic population, the power market must be matched, and the demand for environmentally-friendly gas insulated switchgear will also increase with the development of the market; The market potential still needs to be developed. At the same time, due to the integration of multiple functions such as data collection and control, data processing and storage, online monitoring and advanced analysis of switchgear, the product provides online intelligent monitoring and management of the distribution network, enabling it to operate in a safe, reliable, high-quality, and efficient state, achieving remote monitoring, control, and management of the power system distribution network, and meeting the requirements of power grid optimization, electricity safety, energy management, and energy conservation and consumption reduction; The system can also be widely used in intelligent power distribution fields such as transportation, factories, hospitals, schools, buildings, residential communities, and commercial buildings.
