630kVA and 800kVA Cast Resin

We succesfully delivered 2 pcs cast resin transformers of 630kVA and 800kVA to an electrical utility in Finland.

The transformers are replacing transformers in existing compact substations. The space limits for the transformer cells resulted in tailor made solution because of installation of larger sized transformers in terms of power rating. The challenge was to stay within the space limits and to still fulfil the clerance distances.
