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 tde zero halogen low smoke construction, tdis cable is ideal for use in public, commercial and industrial environments.STANDARDS
Basic design adapted to MIL-C-17

Note: Asterisk ** denotes tdat tde standard compliance is optional, depending on tde oxygen index of tde PVC compound and tde 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 Sheatd: 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 tde oxygen index of tde PVC compound and tde overall cable design. LSPVC can also be provided upon request.
