Low Smoke Microwave Cable Assemblies for Shipboard Applications

When burned, PhaseTrack Low Smoke microwave cable assemblies from Times Microwave Systems emit a less optically dense smoke that releases at a lower rate, making it easier for occupants to exit the affected area safely By DA Reporter / 20 Oct 2021

Times Microwave Systems has introduced PhaseTrack Low Smoke (PTLS) microwave cable assemblies for shipboard applications. Providing exceptional phase temperature performance up to 85 ºC, this cable type has the same Low Smoke, Zero Halogen (LSZH) jacket used on Times’ QPL M17 cables for easy cross-reference and qualification.

LSZH cable assemblies are essential in confined spaces where air exchange is minimal, such as onboard ships and submarines. Fire is one of the greatest dangers in these environments, as accumulating smoke can obscure visibility for safe evacuation. When burned, low smoke cables emit a less optically dense smoke that releases at a lower rate, making it easier for occupants to exit and protecting the safety of firefighting operations. Halogen-free materials also produce clearer, whiter smoke for better visibility and do not emit halogen’s toxic off-gases. 

“In a space where large amounts of cable are needed in close proximity to humans or sensitive electronics, LSZH cables are essential,” said Ted Prema, Director of Aerospace Programs. 

“Submarines and ships are classic examples, which is why the military was one of the first adopters of LSZH standards. The microwave systems perform critical operations in these environments and must be designed to work as safely as possible within the application constraints.”

The PhaseTrack cables are available in a range of sizes from 0.2 to 0.6” and address all frequencies from HF through K band, including a variant optimized for minimum loss in Ku band. Cable assemblies can be supplied with any type of industry standard RF interface. The assemblies incorporate the proprietary TF5 dielectric for a low loss, flexible, phase-optimized cable. Its stability is superior to PTFE and free of its notorious ‘knee’.
