Under-oil loadbreak switches

IEEE Std C37.7415 to 38 kV2 and 4 positions
Also known as:sectionalizing switch2 and 4 position switchloop feed switch
Under-oil switches

What is it and when is it used?

The under-oil loadbreak switch mounts inside the tank of padmount and submersible transformers, letting operators open, close or transfer loop-feed circuits without taking the transformer out of service. It is the component that gives underground distribution networks their operating flexibility.

We carry the complete Eaton Cooper Power Series line of 2- and 4-position switches, in ring or bracket mount, with blades for radial or loop-feed configurations.
