Non Segregated Phase Bus: Knowing Its Operation

The non segregated bus duct is fabricated by using top of the line constituents to assure a firm and dependable powers transmit. Bus ducts can be used in range of applications, that is, from switchgear assemblies to unit substations.  Enclosure comes in wide range of choices: NEMA 4X, Stainless Steel, aluminum and NEMA 3R.

Baked on Epoxy, the powder coat offers mechanical durability, scratch resistance and meeting the salt spray needs of ASTM B-117. Detachable enclosure covers are firmly fixed bolt, thereby letting easy access.

Non Segregated Phase Bus joints are protected by bolting the bars by using splice plates on both the sides, thereby offering a solid association. Bus bar is complete conductivity with pure copper. Plastic joints every 50 feet in straight bus runs let bus extension while transferring the rated current.

Fluidized bed epoxy insulation is non-hygroscopic in nature and utmost static. It also defies fungus, mold and tracking. Epoxy resin, dissimilar to other insulations, consistently coats bus configuration. Thermal and electrical performance is improved as the epoxy is straightly tied to the bus conductor, removing the air gap found in other buses. It improves heat transfer and avoids corona discharge and insulation damage.

Bus joints are shielded with flame retardant element that is detachable for joint inspections.

Termination Choices:

  • Potheads
  • Flexible shunts
  • Conductive stub ends
  • Bushings
  • Fire stops
  • Space leads

As per ANSI standards, corona extinction levels are not precise; however they are considered apt for the production type test. Transitory ratings are not specified in the usual; however the duct is predictable to be apt and go with the transitory rating of the equipment to which it is connected. The segregated DC bus duct supposed voltage rating varies from 300 to 3200 volt DC with constant ratings up to 6000A.
