Segregated Phase
  • Segregated Phase Bus Duct is available for voltages ranging from 600V through 38kV with ampere ratings up to 8000 Amps. Segregated phase bus has all phase conductors in a common enclosure with metal barriers between adjacent phases. Conductors are mounted on molded fiberglass-reinforced polyester blocks or on post insulators. This design is primarily used as a generator lead in power plants, but can also be used in heavy industrial applications and as a switchgear tie-in metal-enclosed substation.

  • Typical applications include connections between transformers and switchgears, tie connections between motor control centers and large motors, and as main generator leads for small generators.

  • Aluminum enclosures are standard for Powell. Mild steel and stainless steel enclosures are available to meet a variety of environmental requirements. Outdoor housings are weatherproof with gasketed and peaked top covers, screened breathers, and heaters for control of condensation. The standard finish color is ANSI 61 gray, but special colors can be provided to match connected equipment.

  • Typical of Powell’s flexibility to integrate one product line to another, Powell’s Segregated Phase bus can be part of a large scale project for Power Control Rooms and Offshore Modules.

  • The Powell Team is dedicated to supplying an entire portfolio of bus duct products to meet the specific needs of your application and to ensure that customers and end users receive equipment that are of the highest quality and reliability. Our technical staff is ready and available for consultation to establish the final product configuration that will conform to your most specialized needs.

    • Current: 600 through 6,000 Amps
    • Voltage: Up to 35,000 Volts
    • Insulation levels (BIL): 95kV and 110kV
