Refurbishment and Repair
Transformers can be rewound to accommodate different voltages and varying vector groups to suit customer's specific requirements.
In the event of a transformer failure, engineers will isolate, make safe and disconnect cables/busbars before removing the unit for transport for full test and appraisal.
Winder Electrical has the design and engineering capability to repair and rewind transformers up to 50MVA @ 132kV.
In addition to oil cooled transformer repairs, Winder Electrical can also offer the facility of rewinding and repairing dry type transformers utilising Class 220 insulation.
Upon satisfactory completion of the repair the units are then re-installed, fully tested and commissioned.
Repairs and refurbishment to tap changers can also be undertaken.
Transformer radiator repair and replacement services
On site maintenance, installation and commissioning for transformer and switchgear applications can be arranged
ONAN transformers can be uprated to OFAF by equipping the units with fans and pumps, associated control gear and new radiators if required.

Winder Electrical operates a strict test and inspection procedure on all equipment leaving its premises. The tests comply with all relevant British Standards and are approved by major industrial users and national companies.
