Tyree Industries

Tyree Industries produce traction class power transformer up to 35MVA ONAN, 132kV Class primary voltage. Tyree design philosophy is based on Westinghouse round coil, core type technology. This technology is proven technology for transformers rated from 3MVA, through 300MVA, 330kV. Tyree utilise modern, robust winding technology that is short circui... t designed and verified including continuous disc and interleaved disc for high voltage windings, helical and continuous disc featuring CTC (Continuous Transposed Conductor) for medium and low voltage windings. Tyree are the only Australian transformer manufacturer producing in-house, customised winding conductors including tensile rated and tested high conductivity copper conductors, coated and wrapped to specific design and performance. These techniques and technologies are particularly relevant to traction duty transformers subject to frequent short circuits and voltage transients. Tyree engineers have experience in fielding such products capable of repetitive short circuit and switching voltage impulse. Tyree possess circuit simulation tools enabling load transient modelling to fully model and predict the effects of load current harmonics on winding conductor for accurate thermal profiling in real-world traction environments such as rail systems and propulsion loads. Tyree Power Transformers feature in-house produced radiators. This enables rapid production of custom cooling configurations for ONAN and ONAF ratings. Tyree radiator designs feature welded header, self draining in cold-rolled and stainless steel. Tyree Power transformer tanks are boiler designed and fabricated, featuring Australian Standard tropical and marine rated surface treatments. Tyree engineers utilise best in class power transformer components, sourced globally including On-Load-Tap-Changers (OLTC), Condensor and Oil filled bushings, instruments and fittings. Tyree are Australian engineered for Australian conditions, to world class standards.Read More
