Busbar systems for maritime applications: designed and built to withstand vibrations
Rittal | Vibrations can loosen the strongest screw connections and even cause steel plates to fracture. To eliminate this problem in low-voltage switchgear and control systems on ships and offshore platforms, classification societies have set out defined design requirements and test conditions. Rittal’s busbar systems, key components of switch- and control gear in maritime applications, have been thoroughly tested and type-approved, simplifying the vessel inspection process. Electrical switchgear and control systems on ships and offshore platforms do not differ significantly from those used in industry generally. However, environmental requirements do impose greater demands. For example, clearances and creepage dis tances may have to be increased due to high air humidity, and it may be necessary to verify that ship vibrations cannot loosen screw connections. International standard IEC 61439 defines general requirements for these systems and classification societies usually require application of this standard for marine equipment, in addition to their own more specific demands.
