The specification also allows a wide variety of jacket materials in both single and double wall constructions. The double jacket constructions are to be used in conjunction with the double shields listed above. A double jacket is applied using 2 shields with the inner jacket isolating the shields, plus an outer jacket.

Applications

The NEMA WC27500 specification is commonly used to describe both shielded and unshielded cable constructions for avionics, aerospace and airframe applications. The specification allows the user a wide variety of construction choices. Circuit identification, conductor size, insulation type, number of conductors, shielding material and jacket compound may all be specified using this document.

Although there is not a QPL required for WC27500 in itself, the basic component wires are QPL. Thus, the producer of the finished cable must be a qualified source under the applicable basic wire specification, or must provide evidence that Qualified wire was used in the construction of the cable.

Since RSCC Aerospace and Defense has a large variety of military QPL approvals, it is able to provide one of the widest ranges of WC 27500 constructions of any source in the wire and cable industry. Although this brief sheet cannot list all the detailed testing and specification requirements contained in the complete WC 27500 document, we have summarized the major construction features of the specification and listed those that RSCC produces.
