A compact transformers substation is a piece of electric equipment comprising the step-up transformer, load switches, low-voltage switchgears and other supporting devices. The compact substation is designed by our company exclusively for wind farms. It is an ideal device supporting wind power generation as it can step up 0.69kV discharge power of the wind farm to 35kV and continue the power transmission at the voltage of 35kV. The compact transformers is thus suitable to be used in unattended small substations at 35kV or below. It can be widely applied in industrial substations, 10kV switchgear system and 35kV rural substations.
