Distribution transformers for grid and utility projects

Continuity of supply, at the lowest lifetime cost

A distribution utility is judged on outage hours and on losses it has to pay for. That means the transformer has to run cool, run quiet and survive overload and lightning without failing, and the loss figures have to be the ones on the test report — not a catalogue assumption.

We build distribution transformers with fully sealed corrugated tanks and high-grade cold-rolled silicon steel, in Class-1 and Class-2 energy efficiency versions, so you can choose between lowest first cost and lowest losses depending on how your regulator scores the project.

• Distribution transformers from 30 to 2500 kVA at 10, 20 and 35 kV, and export voltages of 6.6, 11, 22 and 33 kV
• Pole-mounted single-phase units from 5 to 160 kVA for rural and residential feeders
• Terminal and ring packaged substations with HV room, transformer room and LV room in one enclosure
• Ring main units and metal-clad withdrawable switchgear to complete the line up to the LV side

Documents that hold up in a tender

• Type test report and energy efficiency report for the S13, S20, S22 and SC(B) series
• Routine test records for every unit: ratio and vector group, winding resistance, no-load and load loss, applied and induced voltage, insulation resistance
• Dimensional drawings, weight and oil quantity for foundation and crane planning
• English nameplate and instruction manual
• Packing and container loading plan before shipment
