B3) three core 22-16awg overall foil screened

Three core 22-16awg overall foil Belden alternative data cables are designed for use in instrumentation, security, data, bus & audio applications. The overall foil tape screening on this cable type provides protection against electrical interference.

These alternatives to Belden cables are flexible and come in polyvinylchloride (PVC) or low smoke and fume (LSF) as standard.

LSF material offers reduced smoke emission / fire propagation compared with standard PVC but may still release hydrogen chloride (HCL) if burnt. There is no standard governing the HCL emissions of LSF cable. LSF should not to be confused with Low Smoke Zero Halogen (LSZH) which guarantees max. 0.5% HCL emissions, for more information please see the in-depth explanation shown on our LSZH Control Flex front page.

These cables are often available in Armoured, Duct Grade or LSZH versions on request, please contact us for more information.
