Cable Drawing A3206001_Rev.pdf

This is a Specification Control Drawing for a Special Purpose Electrical Cable manufactured to military standards. The drawing, designated as CABLE, SPECIAL PURPOSE, ELECTRICAL, 24-1932 AWG, specifies detailed requirements for an insulated electrical conductor assembly intended for U.S. Army Communications-Electronics Command at Fort Monmouth, New Jersey.

The cable assembly consists of multiple conductor types with specific insulation and shielding requirements. Type A comprises twisted pair insulated conductors with silver-plated copper (24-1536 AWG with .58 nominal OD, white-blue insulation, and tin-plated copper shield at 38 AWG with 90% coverage minimum). Type B utilizes two twisted pairs of tin-plated copper (18-1930 AWG with 1.2 nominal OD) in red-black and yellow-violet color combinations. Type C specifies tin-plated copper (20-1932 AWG with .94 nominal OD) in orange insulation per MIL-STD-104. The assembly includes mechanical specifications requiring extruded PTFE insulation, thermoplastic rubber filler, clear Mylar isolator with .02 thickness and 50% minimum overlap, tin-plated copper braid shield at 36 AWG with 90% coverage meeting 500 milliohms per meter maximum at 100 MHz, clear Mylar separator, and extruded polyurethane jacket with color blue and nominal 1.00, 9.7 OD. All materials must meet MIL-C-27500 requirements and be non-hygroscopic with no nutrient-supporting fungal growth, with the jacket capable of pushing back 3 inches. The operating temperature range is -55°C to +80°C. Suggested sources of supply include Teleflex Electronics (Hickory, NC) and Cable USA (Naples, FL). The drawing was initially released on December 2, 1952, and issued with preliminary revisions marked as X=44.
