ÒÓ Ó 31.3-00214534-055:2006
Fire-resistant power cables with copper conductors, XLPE-insulated, galvanized steel-tape armoured, with low fire-risk PVC-compound outer sheath
Cables are used for laying:
• in bunches
• in premises, dry ducts and tunnels, in corrosive environment
• in places, where small mechanical impacts on cable are possible, including tensile forces
• in bunches, in crowded places
• power supply cable lines of NPP safety system equipment, circuits wiring of fire safety systems (fire alarm circuits, power supply of fire-fighting pumps, lightning of emergency exits and evacuation routes, smoke exhaust and blowing ventilation systems, evacuation elevators); for wiring in hospital surgical wings, emergency and equipment (current collectors) power supply circuits, operating in a fire emergency
Manufacturing of extruded fire-resistant barrier is possible
Fire safety code in accordance with ÄÑÒÓ 4809:2007: ÏÁ123121080
