TECHNICAL OVERVIEW

Selected as a system, not as an isolated item.

Selection is based on rated power, HV and LV voltage, vector group, impedance, losses, tap range, cooling, insulation level and approved project tests. The current catalogue covers oil-immersed distribution units up to 36 kV and a 120 MVA industrial substation power-transformer reference.

BUYER QUESTIONS

Direct technical answers.

Can transformers be included with the complete line BOQ?

Yes. Transformer items can be coordinated with poles, mounting steelwork, arresters, fuse cutouts, connectors, grounding and LV accessories.

Are transformer values finalized from capacity alone?

No. Voltage ratio, vector group, impedance, losses, tap range, insulation level, accessories, environment and testing must also be confirmed.
