2012 – 2014
The task
A 2.5 MW full-power converter for onshore wind turbines requires an enclosure that is robust under harsh conditions, service-friendly in confined tower spaces, and thermally optimised for continuous high-power operation. The design had to accommodate a complete water cooling system, a DC/AC copper busbar network, and a plug-in rack system — all within a welded steel frame.
Our contribution
Complete 3D mechanical design in SolidWorks — from concept to production-ready documentation:
• Welded steel frame with plug-in rack system (60+ assemblies)
• Water cooling system — cooling plates, manifold pipes, hydraulic brackets, seal frames
• Copper busbar network DC / grid / PE
• Reactor mounting, drawing set + BOM Rev.06, test & acceptance specification
The result
A series-ready full-power converter enclosure for 2.5 MW onshore wind turbines — complete with 3D model, 2D drawings, BOM, and test & acceptance specification.
