Product details

Rated at 1, 5 or 16 MVA, this three-phase oil-immersed transformer brings a 110 kV supply down to 20 or 35 kV for substation and industrial use. Manufactured to IEC 60076, it combines a sealed steel tank, radiator cooling and a conservator oil-expansion system to deliver dependable, efficient transformation over a long service life. Copper and aluminium winding options are both available, and the unit meets IEC/GB requirements.

Design & Construction

Three high-voltage porcelain bushings sit atop the sealed steel tank, alongside a conservator for oil expansion, side-mounted radiator banks, and a cabinet for monitoring and protective devices. The oil-immersed build keeps cooling efficient and insulation stable, supporting long-term operation in both substation and industrial settings.

Applications

Suited to utility and industrial substations, transmission and distribution networks, renewable-energy installations, and large facilities needing 110-kV-class transformation.

Customisation Options

Capacity, HV/LV voltage, vector group, tap-changer arrangement, cooling class and fittings can be configured to a project's single-line requirements.
