SF-6 INSULATED RING MAIN UNITS (RMU) UPTO 22KV
We are pleased to offer our metal enclosed SF6 insulated compact switchgear type Safe Plus. The switchgear system is tested according to all relevant IEC standards. Safe Plus is a completely sealed system with a stainless steel tank containing all the live parts and switching functions. A sealed steel tank with constant atmospheric conditions ensures a high level of reliability as well as personnel safety and virtually a maintenance-free system.
It can be supplied in various configurations. It offers extendibility and fully/semi modular configuration possibilities. It can be made extendable on both sides for expansion. Metering cubicle can be added to it separately within the RMU.

a. 11KV Outdoor Vacuum Circuit Breaker Type : SDB-12S :
It has current rating upto 1600A Or Type : OVB-SDB-15.20.25 with current rating of 2000A and Short time withstand current of 26.3KA/3sec. It is designed and type tested to meet requirements of IEC-60056 / IS : 13118
Salient Features :
- Porcelain Clad Construction, suitable for outdoor sub-station layouts
- Fully Type Tested
- Guaranteed for long electrical life with proven vacuum interrupters and excellent arc quenching and insulating properties of vacuum
- Guaranteed for long mechanical life
- Minimal operating energy required enabling use of simple, reliable and proven low energy spring operating mechanism
- Re-strike free
- Suitable for auto-reclosure duty cycle
- Mechanical Operation counter
- Easy to install-structure mounted, with an option to extend structure for mounting of instrument transformer
- Complete breaker can be shipped as one single unit-no adjustment required at site
- Applications-capacitor switching, distribution networks, arc furnace duty, switching unloaded transformers and reactors
It is available in a current rating of 1250A and above and will have a STR of 31.5KA / 3sec It is designed and type tested to meet requirements of IEC-62271-100,CEI 17-1 file 1375 and CENELEC HD 348 S6 Standards The CB can be used for indoor/Outdoor use. Only the Outer Panel changes
Applications:
Used in power distribution for controlling and protecting lines, substations and transformer and distribution substations, transformers, rectifier units, capacitor banks etc
Thanks to SF-6 AUTOPUFFER breaking technique, they do not generate over voltages and are therefore highly suitable for retrofitting, upgrading and enlarging older installations where the insulating materials of the cables and apparatus may have been stressed during service.
