Manufacturer family/application source. GE Vernova publishes mining primary substation transformer applications and distribution ratings to 5000 kVA/34.5 kV. The public family reference does not certify a specific IECEx/Ex-d nameplate; explosion protection must be confirmed separately. Exact order code, guaranteed losses, dimensions, insulation level, cooling stage, winding material and project options must be confirmed with the OEM before procurement or an SLD study.
