Three phase surge surppression transformer

With the occurrence of lightning, the induced electric charge on the power lines produced by electrostatic
induction could damage any electronic equipment. This Surge Protection Transformer, equipped with
sufficient insulation and shielding against surge voltage, is very effective in protecting your electronic devices
against induced lightning surge.
