MIL-C-55021 | NEMA WC 55021

The MIL-C-55021C covers electrical cables consisting of unshielded and unjacketed, shielded, jacketed, or shielded ad jacketed twisted pairs and triples, and shielded or shielded and jacketed singles. The cable is intended for internal wiring of electrical equipment for applications of -40°C to +105°C (M55021/1) and -65°C to +200°C (M55021/2). Cable constructed with PVC insulation or jackets are not to be used in aerospace applications.
