COMPANY PROFILE<\/span>\n

40 MVA Transformer<\/h1>\n

Subian Electric manufactures 40 MVA (40,000 kVA) oil-immersed power transformers for 110kV and 132kV substations. At this rating the transformer is a regional grid asset: it steps transmission voltage down to 10.5kV, 35kV or 6.3kV for a substation busbar, and serves utility, industrial and urban supply projects.
Our 110-132kV series covers 6,300-63,000 kVA, so the 40 MVA rating sits inside the standard production range – built to Type 10\/11\/13 loss designs with YNyn0d11 connection, 10.5% short-circuit impedance and ONAN\/ONAF cooling. Every unit is core-and-coil built in-house, vacuum dried, oil filled under vacuum and routine tested before dispatch.
Send your voltage combination, impedance and loss requirement, or your load-flow study, and our engineers will confirm the 40 MVA specification with weights, dimensions and a written factory quotation.<\/p>\n
