AT Tapchangers Single compartment units The AT range of single compartment units with high-speed resistor transition are designed for three-phase systems with voltages of 44kV and 66kV line end or 132kV neutral end and nominal rated current of 300A. A maximum of 17 tapping positions (16 steps) 15 possible for linear regulation and 33 tapping positions (32 steps) for reversing of coarse/ fine regulation. The AT tapchanger is designed such that power flow can be handled in either direction at full-rated current. The AT is a flange-mounted tapchanger where the oil in the switch compartment is kept...

The AE series on-load tapchangers are built on the successful results of the design of the AT range. The AE uses many common parts from the AT including the complete drive mechanism. This range has a maximum of 17 tapping positions (16 steps) and is possible for linear regulation and 33 tapping positions (32 steps) for reverse or coarse/fine regulation. The equipment may be used to regulate three-phase transformers designed for system voltages of 33kV and 66kV at any position in the winding. Specification • 500A current rating • Suitable for 33kV or 66kV systems, line or neutral end • Suitable...

BRUSH Design BRUSH has achieved a history of manufacturing spanning 125 years by refusing to compromise on performance, quality or reliability. BRUSH BRUSH Transformers strive to ensure that our products and services consistently provide the best value, and are suitable for each of our customers individual needs. From the initial stage of any project, with a design department that employs a wealth of experience to develop product specifications, combining a high degree of engineering integrity with the necessary commercial, practical design and quality considerations. This ensures that our customers...

BRUSH All transformers supplied by BRUSH have the CE marking on the transformer rating plate as a sign of compliance. The no load and load losses are also indicated on our transformer rating plates. Tier 2 is due to be enforced in July 2021 which will require all new transformers to be a further 10% efficient. However, BRUSH already supply transformers with Tier 2 efficiency to DNO's within a framework agreement. BRUSH Transformers met this requirement in 2016 in advance of its enforcement date of 2021. BRUSH Transformers use high quality electrical steel with Hi-B material and efficient flux...

Transformer Manufacturing BRUSH Transformers are manufactured to the highest standards in our computer controlled factories, with every step of the manufacturing process monitored and tested to guarantee quality. Controlled Environment A dust free shop floor provides a clean controlled environment for transformer assembly. Air Cushion Transporters The movement of core and coils and assembled units within the factory is performed using air cushion transporters on moving pallets. The air cushion transporters and moving pallets are capable of handling weights of 100 tonnes and can be operated in...

BRUSH Drying of Core and Coils The core and coils are dried in the vacuum drying oven, using an advance computer system that records all processes and curves, controls the temperature, vacuum degree and drying time. Compared to conventional ovens, our vacuum oven ensures uniform drying of the active part to achieve a designated level of 0.6mbar vacuum (0.5% Moisture). Final Assembly Upon completion the fully assembled core and coils are dried in the vacuum oven, fitted into the transformer tank and filled with oil under a vacuum. This is followed by an oil processing system using de-aerated oil....
