33/35 kV Oil-Immersed Power Transformer
Project-engineered transformer options for grid interconnection and high-capacity industrial systems.
OVERVIEW
Configured for the actual electrical system.
The coordination process starts with system voltage, MVA duty, insulation level, impedance, losses, cooling, tap range, transport limitations and site conditions. Quotations are compared on an aligned technical schedule before a manufacturing partner is selected.
Typical ranges on this page are for preliminary project selection only. Final design, materials, performance, tests, certificates and supply scope are subject to the signed project technical agreement and the selected manufacturing partner.
