Pressure Drop in a Model of a Forced Cooled Pipe-Typr Electric Cable System with Cable Snaking

An experimental study was conducted of the pressure losses in a scale model of a high pressure oil filled (HPOF) pipe cable system with a wave-like snaking pattern of the cables inside the pipe. In HPOF systems, snaking can be caused by longitudinal thermal expansion of the cables between fixed points of support when the cables are placed under electrical load. Friction factors were determined for a Reynolds number range of 200 to 3800 and longitudinal expansion up to 13.2 percent for cables with and without wire wrap (skid wires).
