Warmly celebrate the successful acceptance of the 12kV environmentally friendly gas-insulated ring main unit (box) successfully developed by our company

Date：2021-8-30

In order to respond to the call of national energy conservation and environmental protection, and help China's goal of "carbon peak and carbon neutrality", our company has newly developed a 12kV environmentally friendly gas-insulated ring main unit (box), and invited the leaders of China Electric Power Research Institute, Shanghai Test Station, and Provincial Ministry of Materials to conduct on-site acceptance, and successfully passed the product acceptance on August 30, 2021. Environmental protection gas insulated ring main unit (box) has the characteristics of simple structure, flexible operation, reliable interlocking, convenient installation, for a variety of different applications, different users can provide satisfactory technical solutions, our company is on the basis of the traditional ring main unit to make major innovations: (1) on the basis of air insulation to achieve miniaturization, compact structure; (2) An air-insulated sealed box with self-healing ability was developed; (3) The operating mechanism with high reliability separation circuit breaker switch has been developed. The environmental protection gas insulated ring main unit (box) is small and compact, occupies less than a quarter of the traditional products, saves precious land, has high reliability, long life, maintenance-free design, greatly reduces the comprehensive investment in the whole life cycle, does not use SF6 gas and solid insulation technology, and meets the requirements of social green environmental protection; It is also suitable for smart distribution grids, and can also realize fault isolation in place, quickly restore power supply, and greatly improve the reliability of power supply; The product scheme is also included in the Southern Power Grid, the State Grid and the procurement catalog, is the power grid to promote the low-carbon, environmental protection, intelligent new technology products, the full range of application solutions free combination, modular design, can be quickly expanded, to achieve the maintenance of equipment, improve the reliability of power supply, enhance the safety of personnel, to meet the needs of economic and stable operation.
