Switchgear and Transformers
| Areva T&D | ||
The Transformer Services Department of Areva T&D's service business can provide specialist technical services associated with the provision of spares, inspection, maintenance, movement, installation, disposal, repair and up rating of transformers and tapchangers |
The Company’s Service Engineers have working experience on tapchangers of all manufacturers and are qualified to carry out major maintenance on all types, at site or at the Stafford Transformer works on a single or term contract basis. |
We have extensive experience in the movement and relocation and uprating of all sizes of transformers up to the largest Generator and Transmission units, in countries all over the world. |
The Drycol Refrigerated Breather System. Transformers operating at high voltages must have their insulating oil and paper insulation as dry as possible in order to prevent failure due to the accelerated ageing effects. |
The Drycol Breather (A) operates by drawing moist, warm air (B) from an air space or from outside via the air inlet tube (C), and returning it to the conservator (D) as cold dry air. A series of thermoelectric modules are used to alternately cool and heat the units vertical central duct (E) in an automatic continuously repeated cycle, extracting moisture as frost and ice, and melting it to escape via a drain tube (F). |
