Shielded cable devices are formed of a conductive loaded resin-based material. Non-insulated conductors with shields, coaxial shielded cables, twisted pair shielded cables, and multi-wire shielded cables are described. The conductive loaded resin-based material includes micron conductive powder(s), conductive fiber(s), or a combination of conductive powder and conductive fibers in a base resin host. The ratio of the weight of the conductive powder(s), conductive fiber(s), or a combination of conductive powder and conductive fibers to the weight of the base resin host is between about 0.20 and 0.40. The micron conductive powders are formed from non-metals, such as carbon, graphite, that may also be metallic plated, or from metals such as stainless steel, nickel, copper, silver, that may also be metallic plated, or from a combination of non-metal, plated, or in combination with, metal powders.
