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.
Built to order, this three-phase oil-immersed transformer is rated 2500 kVA and steps 66 kV directly down to 415 V for industrial and distribution power feeds. It uses a sealed steel tank, radiator cooling and a conservator oil-expansion system, designed for a 20-year service life and configured around each project's single-line diagram. Windings come in copper or aluminium, meeting IEC/GB requirements.
High-voltage porcelain bushings sit on the sealed tank next to a top-mounted conservator for oil expansion, side radiator banks, and a control cabinet for monitoring and protection. Engineered for direct 66 kV / 415 V supply, the oil-immersed design keeps cooling efficient and insulation stable for long, dependable industrial service.
Suited to industrial plants, mining operations, infrastructure projects and distribution networks that need a compact 66-kV-to-415-V step-down unit.
Capacity, HV/LV voltage, vector group, tap-changer type, cooling class and fittings can be adjusted to a project's single-line requirements.
The rated capacity is 2500 kVA, with an input voltage of 66 kV. Other ratings in the same series are quoted on request.
