Figures shown reflect the supplied product data. Exact dimensions, materials, finish and packaging are confirmed at sample approval and order confirmation.
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 cut operating cost, this three-phase oil-immersed transformer is rated 25 or 30 MVA and steps a 66 or 110 kV supply down to 23 kV for substation and distribution use. Low-loss core and winding materials reduce both no-load and load losses across a 20-year design life. It's built with a sealed steel tank, radiator cooling and a conservator oil-expansion system, using copper or aluminium windings that meet IEC/GB requirements.
High-voltage porcelain bushings sit on the sealed tank alongside a top-mounted conservator for oil expansion, side radiator banks, and a cabinet for monitoring and protection. Low-loss materials trim lifetime running costs, while the oil-immersed build keeps cooling efficient and insulation stable for dependable substation service.
Fits utility and industrial substations, transmission and distribution networks, renewable-energy installations, and large facilities that need efficient 66–110-kV-class transformation.
Capacity, HV/LV voltage, vector group, tap-changer type, cooling class and fittings can be tailored to a project's single-line requirements.
The rated capacity is 25 / 30 MVA, with an input voltage of 66 / 110 kV. Other ratings in the same series are quoted on request.
Energy-saving, low-loss design lowers no-load and load losses; 25 / 30 MVA rating covers 66–110 kV substation and distribution needs; Sealed oil-immersed tank with radiator cooling and conservator.
