scope:

This specification covers electrical cables consisting of unshielded and unjacketed, shielded, jacketed, or shielded and jacketed twisted pairs and triples, and shielded or shielded and jacketed singles. The cable is intended for internal wiring of electrical equipment for application temperatures of −40°C to 105°C, or −65°C to 200°C.

The type designation of cable shall be in the following form, and as specified (see 6.2). Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: Electronic Support Division AFLC, 2750 ABW/ES, Gentile AF Station, Dayton, OH 45444-5400 using the self-addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.

Type designation example: E24C904-903-902STW

The type of wire is identified by a one or two-letter symbol as specified in table I. TABLE I. Type of wire.

Symbol Wire 1/ Conductor 2/ Voltage 2/ Maximum 2/ type specification size rating temp. rating ---------------------------------------------------------------------------------- B MIL-W-16878/1 14 to 32 AWG 600 V 105°C C MIL-W-16878/2 12 to 26 AWG 1000 V 105°C D MIL-W-16878/3 1/0 to 24 AWG 3000 V 105°C E MIL-W-16878/4 10 to 32 AWG 600 V 200°C EE MIL-W-16878/5 6 to 32 AWG 1000 V 200°C BJ MIL-W-16878/17 14 to 32 AWG 600 V 105°C CJ MIL-W-16878/18 12 to 26 AWG 1000 V 105°C DJ MIL-W-16878/19 1/0 to 24 AWG 3000 V 105°C 1/ MIL-W-16878 shall not be used for aerospace equipment. 2/ For information only.

The conductor size is identified by a one or two digit number which indicates the American Wire Gauge (AWG) size.

The conductor material is identified by the letter "C" for copper or the letter "S" for copper clad steel or "H" for high strength copper alloy.

The color code of each individual wire is identified by a number built up from the digits designating the colors as specified in 3.3.1. For single shielded and single shielded and jacketed constructions a dash shall not be used. The color code designators for wires 2 and 3 of a twisted pair and triplet are separated by a dash. Two groups of numbers indicate a twisted pair, three groups indicate a twisted triple. Any order of color code designators is acceptable.

The covering of the finished cable is identified by a one, or two, or three letter symbol, following the color code, as indicated below.

Symbol 1/ Covering over finished cable U Unjacketed and unshielded P Polyvinyl chloride (PVC) jacket F Fluorinated ethylene propylene (FEP) jacket J Polyamide jacket T Polytetrafluoroethylene (PTFE) jacket S Shielded and unjacketed SF Shielded and covered with FEP jacket SP Shielded and covered with PVC jacket SJ Shielded and covered with Polyamide jacket STW Shielded and covered with wrapped PTFE jacket STX Shielded and covered with extruded PTFE jacket
