Cable properties

Meter indicator

For ease of installation these bulk cables are provided with an indication on every meter of the cable. This enables installers to have a clear and efficient indication of how many meters they still have available on their reel.


LSHF stands for Low Smoke, Halogen Free. This term refers to Halogen free flame retardant thermoplastic material used as a sheathing compound in cables. In the event of a fire or when exposed to high levels of heat, the chemicals in the jacket removes heat from the flame, whilst the reaction produces water as a by-product to help quench the flame.  As a result, the cable will emit very low levels of smoke, and non-toxic levels of poisonous halogen gasses.


Class B2ca is the highest CPR class used in fixed installations, providing the greatest resistance to spreading fire while maintaining the lowest emission of toxic smoke.
