MIL-DTL-55425E
3.3.1 Conductors. Each conductor shall be composed of 7 copper alloy strands as specified in 3.2.1
3.3.1.1 Stranding. The maximum length of lay of the concentric stranded conductor shall be 0.5 inch (12.7 mm),
and the direction of lay shall be left hand. The outside strands shall lie evenly and smoothly around the central strand
without crowding.
3.3.2 Insulation. Each pair shall be insulated with a tight, well centered compound as specified in 3.2.2, with a
minimum wall thickness at any point of .014 inch (.356 mm) when measured as specified in method 1018 of
FED-STD-228. The insulation shall strip cleanly and readily with the use of pliers.
3.3.2.1 Configuration. Each conductor pair shall consist of two conductors in parallel mutually insulated in an
approximate figure eight cross section. The pair colored olive shall have two "V" shaped tracer ridges. They shall be
located and dimensioned as shown on figure1.
3.3.2.2 Separation. Separation of the conductors of each pair is accomplished by snipping the insulation at the
end of the pair midway between the conductors and tearing them apart. The tensile force necessary to separate the
two wires after snipping shall be not less than one pound and not more than three pounds.
3.3.2.3 Overall diameter. The overall diameter of each pair shall be as follows:
Major axis
0.125±.007 in (3.17±.18 mm)
Minor axis
0.083±.005 in (2.11±.13 mm)
Conductor separation
0.038± 005 in (.97±.127 mm) between inside
surfaces of the conductors.
