Since its introduction within the automotive industry in the 1930’s through to its current widespread use in data centers, busway offers a high density, flexible power distribution solution for many applications.

In recent years, the use of “open channel” busway has become commonplace. The open channel construction allows the plug-in (or tap off) sub-distribution units to be placed, theoretically, at any location along the busway. This enables the sub-feed to be positioned directly above or adjacent to its respective load, which in a data center environment would generally be the server cabinet.

Busway distribution systems in general have some common features. One of those is the requirement to couple together multiple sections of busway of up to 10-12ft in length to form the overall required length of busway.

Traditionally, this coupling has been achieved by the addition of a separate set of components, commonly referred to as the “joint pack”.

Furthermore, given the critical nature of this busway coupler, annual thermography should be performed on each joint pack area to check for loose connections.

Overall, this constitutes a very labor intensive and time consuming method of installation which poses an ongoing risk through loose busbar connections.

This new white paper from Anord Mardix explores a fresh approach — integral coupling — which utilizes a unique male and female coupling system that is integral to the individual busway sections.
