A three-phase cast resin transformer for indoor power distribution in commercial buildings, industrial facilities and infrastructure projects. The cast resin coil system provides electrical insulation and mechanical strength. Its oil-free construction is suitable for installations where fire risk, maintenance, ventilation and indoor operating conditions must be considered.

Chinese-market configurations can be reviewed against the applicable requirements of GB 1094, GB/T 10228 and GB 20052.
Export configurations can be designed and tested to IEC 60076-11 or another specified project standard. Final compliance depends on the approved design, guaranteed values and agreed test documentation.
Routine tests may include:
Temperature-rise testing, sound-level measurement, environmental tests, fire-behaviour tests and third-party inspection can be agreed when required.
Please provide the rated capacity, voltage ratio, frequency, vector group, tapping range, guaranteed loss requirements, cooling method, enclosure requirements, site conditions, applicable standard, quantity and destination.
