The isobar range

The isobar range covers:

Isolated Phase Busduct (IPB)
Segregated Phase Busducts (SPB)
Non-Segregated Phase Busducts (NSPB)

Eta-com is a major supplier for design, manufacture, erection and commissioning of lsolated Phase Busducts up to 1000 MW power plants.

Today, we have an enviable track record of having associated with 6 units of 800 MW, 47 units of 660 MW, 33 units of 500 MW, 100 units of 250 MW, 50 units of 150 MW thermal power stations, hydro power plants and nuclear power plants, besides many captive/private power projects of capacity less than 100 MW.

Isolated Phase Busduct (IPB)

Eta-com offers a wide range of natural air-cooled Isolated Phase Busducts with voltage rating of 11kV to 38 kV having current rating of 100 A to 36,000 A, with the short-circuit current withstand capacity of 312 kA/sec. & 844 kA peak.

These IPB’s have applications in all type of generating stations between 50 MW to 1000 MW.

Features

Isolated Phase Busducts are widely used in power generation units
Connection between generator and generator step-up transformer (GSU)
Tap-off connections to unit auxiliary transformers, station service transformers, excitation transformers and LAVT cubicles

Segregated Phase Busduct (SPB)

Eta-com offers a wide range of Segregated Phase Busducts for medium voltage applications from 3.3 kV to 36 kV up to 5000 A 50/60Hz with short circuit capacity up to 50 kA for 3 sec.

Segregated Phase Busducts are widely used in power generating stations and industrial or distribution plants for lower capacity generator connections, inter-connections between switchgear and transformers.

Features

3 Phase busducts with metal enclosure. Phases segregated by non-magnetic / insulating barrier
Designed for IP 55 class of protection and IP54 for indoor busducts
Connection transformer to switchgear
Connection switchgear to switchgear

Non-Segregated Phase Busduct (NSPB)

Eta-com offers a wide range of Non-Segregated Phase Busducts for low voltage applications from 415 V to1000V – 50/60Hz up to 6500 A with a maximum Short Circuit Current withstand capability of 100 kA 1 sec. and 220 kA peak.

Non-Segregated Phase Busducts are commonly used in industrial utilities, power plants for interconnection between switchgear and transformers or switchgear to switchgear
