Isolated Phase Bus Products – high currents with maximum integrity – power generation
Isolated Phase Bus (IPB) is the solution for main generator leads with current ratings from 3kA up to 50 kA. Isolated Phase Bus systems from Technibus are used exclusively for main generator leads where minimal external electro-magnetic fields and maximum phase to phase fault protection is required.
Technibus provides self-cooled ratings up to 31 kA continuous. For situations requiring forced-air cooled ratings up to 50 kA continuous – a factory consultation is necessary to best meet your project needs. For installations that require momentary ratings up to 900 kA peak, Technibus has a solution to meet your specifications as well.
Technibus supplies not only the balance of plant with our low and medium voltage bus product, but can also supply the generator output with ampacities ranging from 3,000 to 50,000 amperes. Our product meets ANSI/IEEE Standard C37.23 and IEC Standards for Metal Enclosed Bus.
