Non-Standard Single Armor Wires

CMP also provide alternate cable glands for when the cable armor wires are outside of the standard range.

This is especially true for single wire armor cables (SWA), where a change in the wire size can affect the cable gland selection.

IEC 605021 outlines the nominal wire sizes that should be used in relation to the cable bedding diameter.

There are two possible, and different outcomes, when there is a variation in the armor wire thickness, one being a different nominal size of wire is used in the cable manufacture, and another being the nominal wire thickness being over or under size. Details of these alternatives are included in the table below.
