MIL-W-16878 wire
MIL-W-16878 (NEMA HP3, HP4) wires are general-purpose, medium and high-temperature hookup wires,
with PTFE or FEP insulation. Each insulation type is available in thin, medium, or heavy wall thickness, for
voltage ratings from 250 to 1,000 volts.
Conductor choices within MIL-W-16878 are solid or stranded copper, high-strength copper alloy, or
copper-covered steel; with silver, nickel, or tin plating.
