Control screened flame-retardant cables with copper conductors, low fire-risk PVC compound insulation, PVC compound sheath, low smoke and gas emission
Cables are used for laying:
• in premises, dry ducts and tunnels, in corrosive environment
• with no risk of mechanical damage in operation
• in bunches, in crowded places
• with the need to protect from the effects of external electric fields
Fire safety code in accordance with ÄÑÒÓ 4809:2007: ÏÁ123121000
Products of this mark meet the requirements:
• single wire cable flame retardance
