MIL-C 27500 NEMA WC27500

NEMA WC27500 (Formerly MIL-DTL-27500)

 

How to Build a Cable

 

This specification allows an almost infinite combination of wire, shielding. and jacketing materials.  Cables may be unjacketed, jacketed, shielded, or shielded and jacketed.  Care must be exercised in the selection of components to assure compatibility 

[For example, a tin plated shield will corrode or melt if placed under a PTFE (06) jacket.]
