Transformers for Unmanned Submarines

Description

These two transformers, for undersea research and recovery vessel application in depths of six miles, lends itself to a wide range of applications such as mapping the ocean floor, retrieval of undersea objects, recovery and scrap operations, and more.

One transformer reduces the umbilical cable voltage from 2500 – 3000 V to provide six isolated 110 V, 4200 VA outputs, and then matched with another transformer at the other end of the unmanned submersible powers the propulsion motors, robotic arms, lights, cameras, and other instrumentation. The matching transformer on the operating end has inputs of 220/380/440 V, 50/60 Hz stepping up to 2500-3000 V.

The transformers are placed in a mineral oil bath for cooling and insulation and are impregnated using a thermally conductive epoxy resin to allow travel to the ocean floor. The cable connecting the operator and unmanned submersible can be up to six miles long with a voltage drop proportional to the length of the cable.
