MIL-W-81822
wire
MIL-W-81822 (SAE AS81822)
wires have solid conductors for wire-wrap termination, with extruded
insulation of PTFE, PTFE with polyimide hardcoat, or ETFE. Each insulation type is available with a choice
of three silver-plated conductor materials (see below). All are rated at 300 volts.
Some sizes are available in thin-wall versions—these are noted in the tables on the following pages
as MIL-W-81822 numbers with “V” following the AWG size.
