Halogen-free single-core wires are used for installation in dry environments for wiring up lighting fixtures and units where valuable assets
are to be protected from further damage resulting from fire. These cables may be installed on, in and beneath plaster, as well as in closed
installation ducts. The direct operating voltages is permitted up to 900 V against ground when they are used in rail-coaches. For the inner
wiring of switch boards and distributors these are to be used with an alternating nominal voltage up to 1000V or a direct voltage up to 750V
BS EN 50525-3-41.
