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. All are rated at 300 volts.

MIL-W-81822/4 wires have thin wall extruded PTFE
insulation with a polyimide top coat for increased
cut-through and abrasion resistance.
All have solid conductors for wire-wrap applications
such as backpanel wiring, with a choice of three
conductor materials.
