Jacket material—24

M27500 - 22 WN1N24

Component wire AWG

Component wire type

WN: MIL-DTL-22759/90

WM: MIL-DTL-22759/89

: PTFE/Polyimide tape with

PTFE tape outer layer

Number of component wires

Shield material—N: Nickel-plated copper

S: Silver-plated copper

M27500 WM and WN cables

are shielded and

jacketed cables with a jacket of FEP/polyimide tape

covered by a PTFE tape outer layer, incorporating

MIL-DTL-22759/89 or /90 wires.

These component wires have a light-weight

composite insulation of PTFE/polyimide/PTFE tape,

covered with PTFE tape, and silver- or nickel-plated

high-strength copper alloy conductors.

These cables can be supplied with Seamless Wrap

PTFE tape component wire insulation and jacket

(see page 87 for details and part numbers).

Performance:

Voltage rating:

600V.

Temperature rating:

Cables with /89 component wires: -55 to 200˚ C.

Cables with /90 component wires: -55 to 260˚ C.

See page 52 for component wire dimensions.

Construction Details

Component wire conductor:

/89 component wires: Silver-plated high-strength

copper alloy;

/90 component wires: Nickel-plated high-strength

copper alloy.

Note:

AWG 26 wires with either plating have

ultra-high-strength copper alloy conductors.

Component wire insulation:

Inner layer: PTFE/polyimide/PTFE tape;

Outer layer: PTFE tape.

Shield:

Nickel- or silver-plated copper braid, 85% coverage.

Jacket:

Inner layer: FEP/polyimide tape;

Outer layer: PTFE tape.

Colors:

Color coded to M27500 (see page 67).

Certiﬁcations also available to NEMA WC27500.
