MIL-DTL-24643/71 Types LSSCF Shipboard Cable

Mil-Spec Military part number MIL-DTL-24643/71 is comprised of a single cable-type designation: LSSCF. This cable is rated at 1000 volts. 24643/71 cords use flexible extruded silicone insulation and have an outer flexible low-smoke zero-halogen (LSZH) cross-linked polyolefin jacket (XLPO). LSSCF cables are non-watertight with flexing service. These cables can be used within one or two continuous compartments, but are not permitted to penetrate bulkheads or watertight decks.

What does the cable designation LSSCF mean?

In the cable designation for LSSCF, the letters LS refer to low smoke and halogen-free cable. The third letter, SC stands for a single conductor and F represents the flexing nature of the cord.

M24643/71 Construction:

• Conductors: Tin-coated copper conductor
• Insulation: Flexible extruded silicone insulation
• Jacket: Low-Smoke, Halogen-Free (LSZH) cross-linked polyolefin

Features and Benefits of M24643/71 Cords

• Non-watertight
• LSZH jacket is fire resistant and emits low smoke, which is ideal for shipboard settings which often have restricted ventilation
• Portable cords with flexing service permit use in applications where repeated use may require flexing without damaging the cord’s internal conductors
• Silicone insulation has greater moisture resistance, reducing the failure rate that can occur due to excessive moisture condensation in some vessels. 
• Silicone insulation is also highly resistant to fire, and if burned, will generate significantly less smoke and corrosive or toxic gases than other insulation materials.
