Medium Voltage Apparatus

VK Indoor Vacuum Circuit Breaker (Designated sales region)

Application: used to control and protect power transmission and distribution system in the power plant, substation, industrial and mining enterprises, etc. Rated voltage ranges from 12~40.5kV, for making and breaking of load current and overload current, especially suitable for switching important loads and frequent operation.  
Standard: IEC 62271-100

Feature:  

1. Introduction of Toshiba’s advanced product based on state-of-the-art research and development technologies;
2. TOSHIBA vacuum interrupter is used. Combination of reliable breaking capability and longitudinal magnetic field arc extinguishing ability could eliminate the hazards from explosion and fire during switching;
3. Air and epoxy resin are used for insulation, equipped with reliable spring operating 
mechanism, small size, light in weight, compact design, nice appearance;

4. Spring charging mechanism has manual and electric charging functions as well as anti-jumping features. Mechanical and electrical interlock are put in place to avoid mis-operation;
5.The bottom of VK series is equipped with chassis trolley. VY series screw propeller is more effort-saving, stable, having good self-lock features; 
6. Specially designed configuration makes for easy operation and maintenance;
7. Comply with a series of related standards such as GB,DL,IEC,JEC,etc.
