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.
Available in 15, 20 and 25 MVA ratings, this three-phase oil-immersed transformer steps a 110 kV feed down to 35 kV for substation and distribution service. It is factory-built with a sealed steel tank, radiator cooling and a conservator oil-expansion system, designed for 20 years of dependable operation. Windings come in copper or aluminium, meeting IEC/GB requirements.
The sealed tank is fitted with high-voltage porcelain bushings, a top-mounted conservator to handle oil expansion, radiator banks on each side, and a cabinet housing monitoring and protection equipment. Oil immersion keeps the core and windings cool and the insulation stable, supporting reliable long-term substation and distribution duty.
Appropriate for utility and industrial substations, transmission and distribution grids, renewable-energy sites, and large facilities that need 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 diagram.
The rated capacity is 15 / 20 / 25 MVA, with an input voltage of 110 kV. Other ratings in the same series are quoted on request.
