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.
This three-phase, three-winding oil-immersed transformer steps a 220 or 66 kV supply down to a low-voltage output, purpose-built for high-voltage transmission substations. It's constructed with a sealed steel tank, radiator cooling and a conservator oil-expansion system to deliver efficient, dependable transformation at transmission scale. Copper or aluminium windings meet IEC/GB requirements.
The sealed tank carries high-voltage porcelain bushings, a conservator mounted on top for oil expansion, radiator banks along the sides, and a cabinet for monitoring and protection gear. This three-winding, oil-immersed build keeps cooling efficient and insulation stable, supporting reliable service in high-voltage substations.
Appropriate for high-voltage transmission substations, utility and industrial power networks, and interconnection stations requiring 220 / 66-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.
