M24643/18 LSMSCU, LSMSCA, LSMSCS

MIL-DTL-24643/18 (LSMSCU, LSMSCA, LSMSCS)

The M24643/18 cable is a low-smoke, zero-halogen shipboard cable suitable for watertight and non-flexing service. This Mil-Spec cable features multiple stranded bare copper conductors, Silicone Rubber/Glass Braid/Braid covering insulation, and an LSZH cross-linked Polyolefin jacket. The shielded version features a double tinned copper braid shield and the armored version features braided aluminum armor. This cable is suitable for use in power supply, lighting, and weapon control system applications that do not exceed 1000V. The Mil-DTL-24643 Mil-Spec covers cables suitable for use in power supply, lighting, control, communications, instrumentation, and electronic applications.
