This is a Specification Control Drawing for a Special Purpose Electrical Cable (20-1932 AWG) issued by the U.S. Army Communications-Electronics Command at Fort Monmouth, New Jersey. The drawing provides detailed technical specifications and manufacturing requirements for an insulated twisted-pair cable assembly with specific electrical and mechanical properties.

The cable specification includes three insulated conductors with tin-plated copper (20-1932 AWG), a 600-volt RMS maximum rating, and a dielectric strength of 2,500 volts RMS between conductors and between conductor and shield. Mechanical requirements include thermoplastic rubber insulation, a clear mylar isolator at 0.02 inches thick with 50 percent minimum overlap, a tin-plated copper braid shield providing 90 percent coverage, and a polyurethane jacket in black with a minimum wall thickness of 1.00 inches and 8.9 nominal outer diameter. The cable has a maximum weight of 85 pounds per 1,000 feet and must be tested by immersion in a 3-foot saltwater stream for 2 hours without degradation. Packaging must comply with MIL-STD-130. Suggested sources of supply include Teledyne Thermatics (Elm City, NC) and Cable USA (Naples, FL). The drawing was prepared by Art Littlewood, checked by Tamarth, and approved by B. Garvey, with an initial release date of November 27, 1996. All dimensions and tolerances conform to ANSI Y14.5M-1982 standards.
