Dead Tank Type VCB optimized for green procurement. It uses dry air for insulation in place of the SF6 which is specified as a greenhouse gas. Our basic design concept is to realize the environmental factors in design (The 3Rs (Reduce, Reuse, and Recycle) + LS (Longuse & Separable)) and life-cycle cost (LCC) reduction as basic concepts.

Plus, if the gas tank is designed in such a way that it is resistant to corrosion and can keep the SF6 gas pressurised throughout the whole lifecycle of the switchgear, then the SF6 gas can be recovered and recycled for reuse. This reduces the impact of SF6 on environment, while utilising the inherent insulating properties of the gas.
