LSZH Fire Resistant XLPE Insulated Polyolefinsheath Armoured Electrical Power Cable
Property for use
Fire resistant or fire rated cables are designed to maintain circuit integrity and continue to work for a specified period of time under defined flame temperature conditions.
LSZH FR cable is an important cable to be used when you require critical electrical installations to perform during a fire evacuation: fire alarm systems, voice alarm systems, and emergency lighting systems.
They are therefore often specified indoors, especially in public areas, and in other hazardous environments and poorly ventilated areas. This includes cars, aircraft, railway carriages and ships. LSZH sheathed cables are commonly used across tunnels and underground rail networks.
