This Mil-Spec wire is available in conductors sizes ranging from 30 gauge to 18 gauge and is used in applications where lightweight and tight jacket diameters are needed.
With enhanced mechanical toughness, these hook-up wires are offered with extruded insulation of PTFE, PTFE with polyimide hardcoat, or ETFE. Each insulations type is offered in 3 different conduct types, Type A (soft or annealed copper), Type B (soft or annealed oxygen-free copper), or Type C (high strength, high conductivity, Copper Alloy Extruded ETFE).
