Features of Products

20kV Distribution Transformers The abbreviation "change"refers to a static electrical appliance in a power distribution system that converts AC voltage and current
according to the law of electromagnetic induction to transmit AC power. In some areas, power Transformers with a voltage level below 20 kV are called"distribution Transformers"or "
blending"for short. The installation of "matched"places and places is both a substation. Distribution Transformers should be installed on the column or open floor installation.
