CANFORD DKM-LFH - DIGITAL AUDIO OVERALL FOIL SCREENED SOLID CONDUCTOR MULTIPAIR CABLE Low fire hazard

Wiring specifications for many public buildings now call for LFH cables to be used in certain areas, notably in corridors, risers etc. Under combustion circumstances, LFH cables have significantly reduced smoke emission, and the gaseous products contain no toxic halogens.

DKM-LFH is of similar construction to standard DKM, except that the PVC jacket is replaced by LFH materials. The performance is unchanged, although the bending radius is slightly greater as LFH materials are not as flexible as PVC.

Technical Specification:
Conductors: 1/0.4mm (0.126mm²) plain copper
Insulation: High density polyethylene, according to CW1308 colour code (see Technical Data at back of catalogue), OD 0.88mm
Lay-up: Two insulated conductors twisted together, pairs laid up together, and wrapped with polyethylene tape
Screen 1: Aluminium/polyester tape (aluminium side out)
Screen 2: Aluminium/polyester tape (aluminium side in), wound opposite direction to screen 1
Drain wire: 1/0.4mm tinned copper wire, between screens
Overall jacket: LFH material, turquoise
Overall diameter: DKM5 6.0mm, DKM10 7.7mm, DKM25 11.5mm
Minimum bending radius: 75mm
Impedance: 110 ±10 ohms
Conductor resistance: 15 ohms/100m
Velocity ratio: 66%
Propagation delay: Any pair in the cable 243ns/50m (min.), 253ns/50m (max.)
Max. difference between any two pairs in the same cable 5.0ns
Step response: 10-50% transition time 4.5ns/50m (min.), 6.5ns/50m (max.)
10-90% transition time 50ns/50m (min.), 110ns/50m (max.)
Crosstalk: 25dB minimum
Weight (kg/100m): DKM-LFH5 4.3, DKM-LFH10 7.0, DKM-LFH25 15.0
Reel length: 500 metres
Cut lengths: Available in any multiple of 1 metre
