MIL-DTL-55021 (M55021) – Mil-Spec Wire & Cable
MIL-DTL-55021 (MIL-C-55021) electrical cables are intended for use in internal wiring of electrical components with an operating temperature range of -40°C to +200°C (-40°F to +392°F). Cables constructed with polyvinyl chloride (PVC) insulation/jackets are not suitable for use in aerospace applications.
When you order MIL-DTL-55021 cable from A.E. Petsche you can customize your cable to the optimal configuration for your needs by choosing:
- Wire Type – Decide which variety of wire you want for the basic construction of your cable. MIL-DTL-55021 cables use M16878 spec wire, which is available in several varieties.
- Conductor Size – Select the gauge and strand count of your cable from 26 AWG with 7 strands to 10 AWG with 37 strands.
- Conductor Material – Choose from copper, copper clad steel, or high strength copper alloy.
- Color Coding – Identify characteristics of each of the three wires in your cable with a 10 color code.
- Outer Covering – Choose from 11 different shield/jacket options.
MIL-DTL-55021 identification options include printing of the military spec number, manufacturers CAGE code number, the configuration options you have chosen, and the year of manufacture on the cable. This Identification can be at intervals of 1-3 feet, and either is printed on the outer jacket or printed on marker tape under the shield or jacket.
Note: MIL-DTL-55021 replaced MIL-C-55021.
