This heavy gauge 2-conductor cable is used on the BlueROV2 to carry power between enclosures. The cable is custom made with a pressure-extruded urethane jacket, Teflon tape, and flexible 12 AWG conductors. It’s really tough and abrasion resistant. The conductor insulation is chemically etched to ensure excellent adhesion to potting compounds and glues.
