3.3 Conductors. Cable, Special Purposes, Electrical WM-46/U shall consist of eight 20 AWG

conductors and two 16 AWG conductors as specified in A-A-59551 for coated type B, class K wire for

ordinary flexing service.

3.4 Conductor separator. A close wind of fine cotton or rayon shall be applied over each conductor.

This separator may be omitted if a free stripping insulating compound is used.

3.5 Insulation.

3.5.1 Physical properties. Each conductor shall be insulated with differently colored insulating

compounds or the same color compound depending on the method of color coding (see 3.6). The

physical properties of the insulation from each conductor shall be as specified in MIL-DTL-3432.

3.5.2 Insulation thickness. The insulation thickness shall be not less than 0.020 inch (.51 mm), or if

followed by a braid or serving over the insulation, the thickness shall not be less than 0.015 inch

(.38 mm).

3.6 Insulation color coding. Each insulated conductor shall be differently color coded with colored

insulating compounds or a color coded braid. The following colors shall be used on the conductors

tabulated below:

Color

Conductor AWG

Black

White

Red

Green

Orange

Blue

Brown

Yellow

Slate

Purple

3.7 Shielded conductors. Five of the insulated conductors, colored blue, brown, yellow, slate and

purple, shall each have an individual braid of tinned soft or annealed copper wire applied over the

insulation or textile braid if used to a minimum coverage of 85%. Each strand of the braid shall consist of

34 AWG wire in accordance with A-A-59551 for coated type S, soft or drawn-and-annealed wire prior to

braiding.

3.8 Cabling. The black and the white conductors shall be twisted together with a lay not exceeding 2

inches (50.80 mm). The remaining conductors shall be cabled around the central conductors with a lay

not exceeding 7 inches (177.80 mm). The outer conductors shall be placed in the same order around the

cable as the order of the colors of insulation tabulated in 3.6.

3.9 Overall shield. A close braid of tinned, soft, or annealed copper wire shall be applied over the

cable conductors to a minimum coverage of 85 percent. Each strand of the braid shall consist of 34 AWG

wire in accordance with A-A-59551 for coated type S, soft or drawn-and-annealed wire prior to braiding.

3.10 Jacket separator. A close wind of fine cotton or rayon shall be applied over the shield.
