MIL-W-81381/12

Insulating Material: FEP and PMDA-ODA

Insulation Thickness: 17 mil ( 0.40 mm)


Wire Properties

Voltage Rating: 600

Temperature Rating: 200 C

Conductor Type: Nickel plated Copper


Construction Details: Two FEP coated PMDA-ODA tapes (both one mil thick) wrapped in an overlapping manner and a modified PMDA-ODA top coat.

Nomex® topcoat on wires size 8 and larger.


Additional Information: For AWG-8 and larger, there will be an Aramid braid over the finished wire without the PMDA-ODA top coat; this adds another 20 mil (0.5 mm) to the overall diameter of the finished wire.
