Overview

◎ This series is puffer interrupting pad mounted fully deadfront switchgear for underground system up to 25.8kV, 600A, enclosed in stainless steel tank full of SF6 gas insulation media.
　 It incorporates grounding switches in every way to provide added safety and faster working. 

◎ Insulation, break, and simple grounding by SF6 Gas
　 - It guarantees perfect break capacity by high insulation and excellent fire-fighting capacity of SF6 Gas.
　 - The danger of fire is none by using inflammable SF6 Gas.
　 - The use of Puffer fire-fighting type in which SF6 Gas is compressed in the cylinder allows excellent opening-closing capacity.
　 - Both the opening-closing surge occurring when using vacuum interrupter and flash over phenomenon by charged electric current of cable do not happen.
　 - The grounding switch inside allows grounding with a simple operation.

◎ High safty, complete maintenance free
　 - The use of inflammable SF6 Gas allows no possibility of fire,so that it can be used at anyplace inside and outside the house.
　 - SF6 Gas is none-toxic, no-harmful with high stability.
　 - Since it is manufactured with perfect sealing-up by TIG welding and simple tools, it does not require maintenance.

◎ Complete water-proof and rust-proof
　 The main body of opening-closing panel is welded with stainless steel, and is covered with resin, so that it has no rust.

◎ Small size and light-weight
　 The insulation method of SF6 Gas and a simple design of operational tools allow a small size and light weight, which minimizes the space for installation.
