Tatung Company has manufactured power transformers since 1964. We had the ability of manufacturing the 345kV 500MVA extra high voltage power transformer in 1984. Today our company has owned the ability of manufacturing every kind of oil-immersed transformer below and including 345kV 800MVA.
The quality of Tatung power transformers has
won good reputation from domestic and abroad customers.
˙ Excellent core construction
Advanced V-notch
and step-lap construction are adopted to obtain the best performances of the core,
such as low sound level, low no-load loss and low exciting current.
˙ Surge-proof winding
An appropriate
insulation arrangement is adopted for the windings according to the analysis of
voltage oscillation program to ensure its ability of surge-proof.
˙ Advanced vapor-phase drying system
Utilizing the
most advanced vapor-phase drying oven to make the insulation material dried
thoroughly without sacrificing its performance.
˙ High-efficiency cooling method
The directed
flow construction adopted in the windings ensures the insulating oil flowing
through all parts of windings rapidly and evenly to improve cooling efficiency
and reduce hottest-spot temperature.
˙ Countermeasure for leakage flux
Appropriate
means are adopted to prevent the local heating from leakage flux.
˙ Sufficient strength against short-circuit electromagnetic
mechanical force
According to the
detailed short-circuit stress calculation by analysis software. Special
attention is paid to provide sufficient strength of windings against the
short-circuit electromagnetic mechanical force.
