F&S Cables - URM Co-axial Cables

URM Co-axial Cable

The URM (Uni Radio-Metric) cables listed cover the majority of high frequency data and signal transmission requirements. Other types can be supplied on request as can armoured, duct grade or versions with alternative sheath colours.

The URM 70 is widely used for security applications connecting CCTV equipment where the stranded conductor centre is less likely to break than the RG59 type. This may be important if the camera is likely to pan and tilt frequently. Other URM cables are available to order.

URM Cables are manufactured generally to BS 2316 part 3.

UL style numbers are given for cross reference purposes only - not all the cables in this section are tested or approved by UL. If you require UL approved versions please tell us when you first enquire.

At FSC we refer to LSHF as Low Smoke Halogen Free

This term is interchangeable with LSZH (Low Smoke Zero Halogen), LSOH (Low Smoke Zero Halogen), OHLS (Zero Halogen Low Smoke) and FRNC (Flame Retardant Non-Corrosive). Beware of the terms LSF (Low Smoke and Fume) or RP (Reduced Propogation), when relating to signal or control cables will normally be modified PVC and produce 'Loads of Smoke and Fume'!

Fire retardant, fire resistant, flame resistant or flame retardant?

These terms are often misunderstood. Most cables when exposed to fire will not carry on functioning. If you require cable to continue working in the event of fire, and in accordance with various standards please call us.
