MAIN LT PANEL

A complete range from main / sub-distribution boards to bus ducts with nominal ratings from 250 A up to 4000 A. Incoming feeder sections and bus-coupler arrangements are available for rated currents up to 4000 A. Power factor correction equipment, if required, can be built into the switchboard. Bus duct arrangement to transformers or between panel sections can be made in the enclosure and bus bar system. This ensures complete integration and provides a professional and uniform design throughout the switchgear room.


DG SYNCHRONIZING PANEL

We offer DG Synchronizing Panels which are based on Auto / Manual sharing, Auto Synchronizing, Auto KW & KVAR sharing and Load dependent start / stop features. Changing of schemes are made through PLC & software which work in tandem with the Generator Control Package Relay that also takes care of power monitoring, communication, display as well as protection. Because of KW dependent load sharing, optimum utilization of DG sets are possible. This increases DG sets efficiency and saves lot of fuel. DG Sets are always tried to run with about 80% load factor, where we get maximum efficiency of DG Sets. Load dependent stop and stop facility can also be incorporated in the logic in order to further save fuel costs and wear & tear of the DG sets. Unequal sizes of DG sets can also be synchronized with special relays and PLC logic. Multiple DG sets can be synchronized.


AUTO MAIN FAILURE PANEL

The AMF panel is connected to the generator set to power control the operational functions. Once a power cut is detected, it automatically signals the generator to start and support the load. It will start the generator if it detects that the mains power fluctuates.


AUTOMATIC POWER FACTOR CORRECTION PANEL

APFC Panel has microcontroller based programmable controller which switches the capacitor banks of suitable capacity automatically in multiple stages by directly reading the reactive load (RKVA) which works in the principle of VAR sensing tends to maintain the PF to 0.99 Lag.


POWER CONTROL CENTER PANEL

PCC panel is a power distribution board to control the power supplied to motors/loads. PCC panels are widely used in refineries, chemical plants, dairies, refrigeration plant, pharmaceuticals and plastic industry.


MOTOR CONTROL CENTER PANEL

A Motor Control Center (MCC) panelis an assembly to control some or all electric motors in a central location. It consists of multiple enclosed sections having a common power bus and with each section containing a combination starter, which in turn consists of motor starter, fuses or circuit breaker, and power disconnecters, A motor control center can also include push buttons, indicator lights, variable-frequency drives, programmable logic controllers, and metering equipment. It may be combined with the electrical service entrance for the building.


METERING PANEL

Metering panels are a kind of control panels which are very much required for the domestic as well as industrial purposes for the measurement of amount of power used up and the rate of power consumption.


FEEDER PILLARS & WEATHER PROOF KIOSK

Outdoor type panels are usually MCC panels / PCC panels / AMF panels / Distribution Panels with a degree of protection of IP 5X / IP 6X. This makes the outdoor type panel fully weather proof and hence provides a longer durability with smooth functioning.


LV BUS DUCT:

  • Bus duct, also known as bus way or busbar trucking system, is an electrical power supply distribution system that seamlessly distributes power from one end of the building to another.
  • Our bus duct systems fulfill four different applications: single loads, multiple loads, riser, and service entrance. Each application is designed according to the site specific requirements, and must all fulfill our objectives of providing our customers with a low-cost, flexible system that is easy to maintain but does not compromise on key safety features
