Flame Retardant Coaxial Cables
Flame Retardant RG11 A/U Coaxial Cables
APPLICATION
The cables are designed for CCTV, security, smoke detection and evacuation monitoring applications, where
continued functionality is required during a fire situation. Due to the zero halogen low smoke construction, this
cable is ideal for use in public, commercial and industrial environments.
STANDARDS
Basic design adapted to MIL-C-17

EN 60332-3-24 (cat. C); IEC 60332-3-24; BS EN 60332-3-24; VDE 0482-332-3; NBN C 30-004 (cat. F2); NF C32-070-2.2(C1); CEI 20-22/3-4; EN 50266-2-4*; DIN VDE 0482-266-2-4 |
Note: Asterisk ** denotes that the standard compliance is optional, depending on the oxygen index of the PVC
compound and the cable design.
CABLE CONSTRUCTION
Conductors: Tinned copper wire, stranded according to IEC(EN) 60228 class 2.
Insulation: Low density PE.
Overall Screen: Plain copper wire braid
Outer Sheath: Thermoplastic PVC compound. UV resistance, hydrocarbon resistance, oil resistance, anti rodent
and anti termite properties can be offered as option. Compliance to fire performance standard (IEC 60332-1, IEC
60332-3, UL 1581, UL 1666 etc) depends on the oxygen index of the PVC compound and the overall cable
design. LSPVC can also be provided upon request.
