MIL-DTL-24643 Test

The U.S. Navy introduced the M24643 specifications to alleviate concerns about toxicity, smoke and flammability. This cable design provides flame retardant, low-smoke cables that are approximately equivalent in overall weight, size and electrical components to many older MIL-C-915 constructions available.

This family of low-toxicity, low-smoke cables is mandated for use on any major retrofit projects or all new constructions and conforms to rigid smoke and toxic indexes. 

MIL-DTL-24643 Shipboard Cable Testing Services

VTEC's testing services for the MIL-DTL-24643 shipboard electrical cable specification will ensure cables are flame-retardant and free of halogens and other potentially toxic materials.

If this cable comes into contact with flame, there will be minimal smoke emissions, making it well-suited for situations and applications where security is a concern.

What Are MIL-DLT-24643 Shipboard Cables?

The MIL-DTL-24643 shipboard cable is designed with a zero-halogen, low-smoke jacket. This cable meets the Navy Shipboard Specification Low Smoke (LS). It is available in a wide range of constructions, including non-watertight and watertight, unarmored and armored and flexing and non-flexing. 

All MIL-DTL-24643 cables feature either Cross-Linked Polyethylene (XLPE) insulation or Ethylene Propylene Rubber (EPR), which are insulation materials that make them a requisite for extended use in challenging applications. Most shipboard electrical cables feature a Low-Smoke, Zero-Halogen (LSZH) Cross-linked Polyolefin (XLPO), while armored cables have braided aluminum armor. There are also several shielding options, including individually shielded conductors and overall shields.

Shipboard cables' varying constructions make them suitable for degaussing, instrumentation, communication, electronic, lighting, control and power applications. 

Types of MIL-DTL-24643 Shipboard Cables

MIL-DTL-24643 shipboard cables are assigned a title beginning with the letters "LS" for Low Smoke. Some of these cable types have a variant carrying an "S" on the end to indicate shielding, and others have an "A," which means armored. 

"U" may be added to the end of the MIL-DTL-24643 specification when either of these variants is not present. This classification indicates that the cable is the unshielded/unarmored version.
