USAGE SCOPE
EN50264-3-1 cable is Low Smoke Halogen Free small-size wall-thick single core wire with strong flame retardant. It has better fire resistance and shielding. This unit relates to power and control cables and their associated lines, which can reduce the hazard to people in case of fire and improve the safety of transportation. The insulation and sheath are made of halogen-free materials. In case of fire, this unit can limit the spread of flame, reduce the emission of toxic gases and smoke, reduce the loss of visibility, and enable personnel to evacuate quickly.
Used as a power and control source in the internal or external installation of railway transport locomotives, handling and installation costs are important factors to consider in this environment. EN50264 power cables are used for control, auxiliary and main circuit wiring such as cable TV slings, switches and control panels, bridge, etc.
