2. Transformer Features


① Strong load-bearing capability: this three phase dry type isolation transformer, with 400KVA capacity, has a strong load-bearing capability.

② Anti-interference: because the primary winding and the secondary winding is separated from each other, the transformer has the feature of anti-interference.

③ High output accuracy: the output voltage could be ±2% of rated capacity.

④ Clear display of input and output data: the input voltage, output voltage, and output current are shown respectively in three pointer meters so that you could know the real-time situation of the voltage.

⑤ Copper windings: three windings are all made of copper wire, which strengthens the electricity conductivity and prolongs the service life of the transformer.

⑥ Fast reaction speed: the transformer reacts quickly in changing voltage.
3. Main Advantages

Low power lossThe transformer is of copper materail, which facilitates low power loss.
Strong electricity conductivityThe transformer features in strong electricity conductivity due to the copper material and all new raw material.
IP23 enclosureThe enclosure is painted silver-grey, which effectively protects the main body of the transformer.
