Signal blocking cables with copper conductors, with polyethylene insulation, in PVC compound sheath, with low smoke and corrosive gas emission, with galvanized double-steel-tape armouring, in PVC compound hose with low smoke and corrosive gas emission
Designed for electrical installations of railway signaling, centralization, blocking and automation at a rated voltage of 380 V AC at frequency 50 Hz or 700 V DC
Cables are used for laying:
• in bunches
• in dry cable duct system, tunnels, collectors in corrosione environment
• at the sites, where, along with the requirements for flame retardance are specified requirements for low smoke and gas emission at combustion or smoldering
• in places, where small mechanical impacts on cable are possible, including tensile forces
Fire safety code in accordance with ÄÑÒÓ 4809:2007: ÏÁ123121000
Products of this mark meet the requirements:
• single wire cable flame retardance
• bunched cable flame retardance category A
• toxicity class Tk3 of the combustion products of nonmetallic elements (toxicity index over 120 g/m3)
• class ÄÒê1 on smoke-forming ability by smouldering of non-metallic elements (coefficient of smoke formation from 50 to 500 m2/kg)
• class ÄÏê2 on smoke-forming ability by combustion (minimum luminous flux more than 60 %)
• corrosive class Êê1 of combustion products of non-metallic elements (the number of halogen hydrides less than 150 mg/g, pH less than 4.3, specific conductivity more than 10 µS/mm)
