Product Details

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.
