Maintenance and upkeep of cast resin transformers

Economically efficient, sustainable and requirement-oriented: maintenance instead of new acquisition!

Our service for an extended service life and sustainable reliability of your cast resin transformers

Play it safe regarding your cast resin transformers while reducing their life-cycle costs (LCC) at the same time: the SGB cast resin transformer service will be pleased to help you!

We check, service and repair cast resin transformers of all makes and ensure a continuously trouble-free performance. Especially if a transformer is subject to extreme environmental conditions such as heat, moisture or saline air, regular maintenance and inspection help protect individual transformer elements from premature ageing and wear due to the prevailing operating conditions.
