Product Overview.

SGG series isolation transformer is adapted to the production of 1KVA - 1500KVA between the power of the transformer, isolation transformer primary winding and secondary winding is divided into two completely isolated windings, the winding center layer of copper foil, with anti-interference, deharmonization, energy saving, safe and reliable. As a step-down transformer, the number of turns of the secondary winding is less than the number of turns of the primary connection to realize the step-down voltage, as a step-up transformer, the number of turns of the secondary winding is more than the number of turns of the primary connection to realize the step-up voltage.
