S(B)20(22) Series Oil-Immersed Distribution Transformer

For facilities that operate electrical equipment throughout the day, transformer selection affects both ongoing energy use and maintenance planning. The S(B)20(22) series is designed for energy-efficient distribution, with capacity selected to match the connected load and the requirements of the installation.

Its oil system limits exposure to ambient air as the oil expands and contracts with temperature changes. This helps reduce the conditions that promote oil oxidation and moisture ingress. Inspection and servicing should follow the instructions for the selected model.

The series can be considered for industrial facilities, office developments and residential distribution projects. For installations near occupied buildings, model selection should also take account of the required sound level and the proposed installation location.
