Bus Duct

A bus duct system an effective method of distributing power to your switchboard and other loads. Bus ducts overtime can experience mechanical damage and dust accumulation, which can lead to catastrophic damage. Since bus ducts are mainly used to effectively and efficiently supply electricity to Industrial locations any damage can lead to costly and extensive downtime. In order to protect bus ducts against mechanical damage and dust accumulation, copper or aluminum conductors are used to completely enclose and insulate the bus duct.

Commercial Industrial Electrical Bus Duct

Bus ducts fall into mainly three categories; non-segregated phase, segregated phase, and isolated phase.

  • Non-segregated phase bus ducts: All phase conductors of the duct are all housed in a common metal enclosure with no barriers between the phases.
  • Segregated phase bus ducts: All phase conductors are enclosed in a common metal enclosure but they are segregated by ground metal barriers between each phase conductor.
  • Isolated phase bus ducts: Each phase conductor is enclosed in individual metal housing and is separated by an air spa

Application

All three bus duct systems have all the same ratings and are identical in application. So why chose one over the other? Segregated bus ducts are considered slightly more reliable than non-segregated and isolated. When manufactured, industry standards are meticulously followed to ensure that these bus ducts provide varied voltage capacities in order to meet exact application demands. The segregated bus duct production process takes in consideration various factors like heating effects, thermal effects, electro dynamic force and voltage drop. Due to their rigid design, they offer clients minimal maintenance and reliable functioning.

"After much online searching I asked for an in-house survey by Kohler and Generac generators from local providers. Dustin from Portman won my business. He quickly assessed what size generator was required for a whole house solution. By putting the air-conditioner on a lower priority (the system would shut it down if demand went too high), I got by with a smaller unit. This, also, allowed me to have all the electrical switching done at the meter and not at my inside panel. The contract was signed and an install date selected. As is normal with me I had a few more questions. Dustin quickly answered them all by phone or email. The installation day arrived along with brutally cold weather conditions (5-10 F). They showed up around 9 AM and worked without a break till the job was done around 3 PM. The installation crew (Adam, John and Dennis) were knowledgeable, friendly and took extra precaution to prevent damage to my home."
