For more than 30 years, electrical equipment manufacturers have developed some very attractive busbar and distribution systems (standard busbar profiles & sizes, busbar supports, comb busbar, distribution systems & accessories) to distribute power inside these electrical equipments in an easy and safe way, especially when they are type-tested.
As far as I see it a lot of panel builder use partially or totally these busbar systems …
… depending on their needs, their organisation and their ability to master busbar arrangements by themselves. But some of them are still using “traditional solutions”, using bare copper busbar and busbar supports which are manufactured and/or assembled in a customised way for each need or project.
I believe the trend is more and more to substitute this traditional way of doing busbar to fully type tested solutions which have been validated by tests according to IEC 439, in particular when those busbar systems are installed inside pre-fabricated enclosures also proposed by these manufacturers.
Still, there are some domains where these busbar systems are less employed such as control panels, or in some very specific switchboard market segments where the electrical equipments and switchboards are still manufactured and customised on a case by case basis. (Mining, Marine, HVAC panels etc)
Will these applications continue to have their specific needs and habits, or will we see manufacturers propose standard busbar systems also there ?
