Conventional Non Segregated Phase Bus Ducts

Ranging from up to 3000Amps for the Low voltage systems voltage of 415 Volt to 1.1kV having the fault level of 50kA/75kA for 1 second, with SMC / DMC Supports

Applications

• Interconnection between the Transformer and Switchgear
• Interconnection between the Switchgear and Load control centre / Power control Centre

Low Reactance Interleaved Phase Bus Ducts

Low reactance Interleaved Bus ducts ranging from 3200Amps to 5000Amps for the Low voltage systems, to the system Voltage of 1.1 kV HAVING A FAULT LEVEL OF 50 kA / 75kA & 100kA for 1 second

Advantages over NON Segregated Bus ducts

• This reduces the losses and the Enclosure temperature
• Smaller bus bar cross section than the Conventional NSPB
• Reduces the Bus bar reactance and losses considerably

Medium High Voltage Segregated Phase Bus Ducts

For the Medium High voltage systems Ranging from 1250Amps to 3200Amps/ 5000Amps and Voltage ranging from 3.3kV to 22kV System Voltage having a fault level of 40kA for 3 seconds.( FOR 5000Amps with STC rating of 65 kA for 3 Seconds )

Applications

• Interconnection between High interruption Capacity Switchgear, with High momentary currents and Impulse voltage and for generators up to 40 / 70 MW.
