Abstract
A relatively small diameter tow cable including a plurality of high and low voltage electrical conductors and a high bandwidth optical fiber for both electrical and data transmission between an aircraft and a towed body. The tow cable is implemented by a coaxial arrangement of a central optical fiber encased by a stainless steel jacket surrounded by a first set of high voltage conductors. A second set of high voltage conductors concentrically surrounds the first set of conductors but is separated therefrom by a layer of high voltage insulation. A layer of high voltage insulation surrounds the second set of high voltage conductors and a set of relatively low voltage conductors and their respective return conductors are circumferentially spaced around this layer of insulation along with opposing sets of insulating spacers. A third layer of insulating material surrounds the low voltage conductors and the spacers. Outwardly of the third layer of insulating material are a pair of coaxial strength members comprised of synthetic aramid fibers and which are then covered with a polyester and metallic braid. An outermost jacket of semiconductive material is also provided which serves as an electrostatic drain to ground for the cable.
