More energies and lands are consumed in China in recent years along with fast economic development speed.Higher requirements have been proposed for scale, energy conservation and environmental protection of electrical equipment along with the significant increase of land price and the state’s higher requirements for environmental protection and low-carbon.To satisfy the demands above, Cooper (Ningbo) has developed 40.5kV and 12kV environmental gas insulated switchgear and LSN500 miniaturized compact LV switchgears. On the one hand, miniaturized environment-friendly switchgear can save more than 60% of space occupied by traditional high-pressure switchgear. It not only occupies a small area, but also reduces consumption of steel and copper bars, saving and utilizing energy intensively.On the other hand, the gas insulated switchgear consume environmentally friendly gas instead of traditional SF6 gas, being green, environmentally friendly, causing no contamination and complying with national policies.Miniaturized environmental protection switchgear, featured by a small size and light weight, is applicable to places with a small space, such as residential communities, schools, hospitals, subways, traffic control spots. It can be used not only for indoor power distribution, but also for equipment such as box transformer substation and switching station.In summary, the miniaturized environmental protection switchgear with a miniaturization, economy, environmental protection and well-functioning features has become more popular among customers and extensively used in power distribution projects.
