All M24643 cables are approximately equivalent in size, weight, and electrical components to many of the MIL-C-915 constructions available. These cables feature either Ethylene Propylene Rubber (EPR) or Cross-Linked Polyethylene (XLPE) insulation. These insulation materials make them suitable for long-term use in challenging applications. All of these cables, except for our two Defense Link™ options, feature a Low-Smoke, Zero-Halogen (LSZH) Cross-linked Polyolefin (XLPO) jacket. Armored cables feature braided aluminum armor. There are also many shielding options, including overall shields and individually shielded conductors. The varying constructions make them suitable for use in power, control, lighting, electronic, communication, instrumentation, and degaussing applications.
Each type of MIL-DTL-24643 shipboard cable is given a title that begins with the letters LS, for "Low Smoke". Some of these types then have a variant carrying an "A" on the end, which indicates that it is armored. It may also have an "S" on the end to indicate that it is shielded. When either of these variants is not present, a "U" may be added to the end of the MIL-DTL-24643 specification to indicate that it is the unarmored/unshielded version. For example, MIL-DTL-24643/18 represents LSMSCU, which is the unarmored/unshielded version. Also in the specification is LSMSCA, the aluminum armored variant, and LSMSCS, the tinned copper shielded variant.
