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
FIRE PERFORMANCE:
| Flame Retardance (Single Vertical Wire Test)** | EN 60332-1-2; IEC 60332-1-2; BS EN 60332-1-2; VDE 0482-332-1 ; NBN C 30-004 (cat. F1); NF C32-070-2.1(C2); CEI 20-35/1-2; EN 50265-2-1*; DIN VDE 0482-265-2-1* |
|---|---|
| Reduced Fire Propagation (Vertically-mounted bundled wires & cable test)** | 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.
