Double Busbar Panels
DOUBLE BUS Switchgear Panels with Automatic Bus Transfer Schemes are regularly supplied by us. Their utility is the provision of another set of busbars to supply power when one source fails or the flexibility to share the load on the Grid and / or a separate source. Each busbar is connected through Isolators or Circuit Breakers which are mechanically interlocked so that either one of them operates at one time. Enough protective equipment is provided so that power transfer between the busbars takes place smoothly and safely.
ADAPTER PANELS & CONTROL AND RELAY PANELS
HT Panels are manufactured by many companies. Sometimes there is an existing panel of a particular make and a new panel of another make has to be installed, an Adapter Panel is used to couple the two different types. This is so because the placement of busbars is different for different panel designs. Thus Adapter Panels are used to couple the two different types.
Control and Relay panels are used when a particular panel has to be operated from a different position like a separate common room, either for convenience or due to extreme weather conditions.
SF-6 INSULATED RING MAIN UNITS (RMU) UPTO 33KV
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.
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.
