MIL-W-22759/20, /21 wire—high-strength conductor

MIL-W-22759/20 and /21

wires have extruded

PTFE insulation and a high-strength copper alloy

conductor for greater break strength. They are ideal

for aerospace and other applications requiring high

reliability and break strength, enhanced ﬂex life, and

resistance to high temperatures.

These wires are especially well-suited in applications

where smoke emission, overload stability, and

ﬂammability are major concerns.

For versions of these wires with thinner-wall

insulation and 600V voltage rating, see

M22759/22 and /23 (following page).

Performance:

Voltage rating:

1,000V.

Temperature rating:

/20: -55 to 200˚ C

/21: -55 to 260˚ C

Construction Details

Insulation:

Extruded PTFE.

Conductor:

/20: Silver-plated, high strength copper alloy;

/21: Nickel-plated, high strength copper alloy.

Colors:

Color coded to MIL-STD-104.

Identiﬁcation:

to M22759.
