Distributing panel facility manufacturer, Solar heating system, Smoke reducing device and Electric work
Apply This unit is used to break the load in the distribution of 25.8KV 600A under-the-land line.
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 I 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.
