Designed and tested to IEC / GB. Millenium production is certified to ISO 9001, ISO 14001 and ISO 45001; the product family carries CE (ECM), UDEM attestation and an EAC declaration of conformity. Every unit passes routine factory tests before dispatch.
Designed to bring 11kV or 33kV supply down to 415V, this three-phase oil-immersed power transformer serves utility and industrial distribution networks that need dependable medium-voltage conversion. It spans a capacity range of 1000kVA up to 10MVA, is offered with either copper or aluminium windings, and runs efficiently at 50Hz or 60Hz. A fully sealed tank paired with corrugated radiators keeps cooling performance consistent under load.
This unit fits naturally into 11kV/33kV utility substations, industrial power supply setups, distribution networks, and infrastructure projects where dependable medium-voltage transformation is required.
Project needs can shape the capacity, voltage ratio, vector group, cooling configuration, and certification. Copper or aluminium winding material is also available on request.
When placing an order, please specify the rated capacity, primary/secondary voltage, frequency, vector group, and the standard that applies.
The rated capacity is 1000kVA – 10MVA, with an input voltage of 11 kV / 33 kV. Other ratings in the same series are quoted on request.
