Rosh Engineering has vast hands-on experience in on-site transformer repair and refurbishment works with high precision quality following strict safety procedures to personnel as well as environment. The service includes the following:
The cooling radiators of a transformer are the weakest physical element and do not withstand much corrosion before there is a risk of oil leak. Modern plate type radiators are manufactured using plate steel sometimes no thicker than 1mm. A leaking radiator is therefore difficult to repair and requires replacement to prevent environmental damage and potential transformer failure.
Cooler banks requiring new A Frames and feed pipes through to straight forward detachable radiators can be supplied and fitted. Coolers that are welded into the tank side such as elliptical tube radiators can also be replaced. On-site cutting and welding of new ports to accept detachable radiators is with Rosh Engineering’s capability. If needed transformers up to 20Tonnes can also be returned to Rosh’s own facility.
