MTA-B-C-D-Y

Flame Retardant RG11 A/U CWB/SWB/SWA Armoured Coaxial Cables

APPLICATION

This cables are used for interconnection of distribution boxes and end devices, where continued functionality is

required during a fire situation. The cables are very suitable for various indoor and outdoor applications,

including routing between buildings within ducts and inside building up to riser shafts.

STANDARDS

Note: Asterisk ** denotes that the standard compliance is optional, depending on the oxygen index of the PVC compound and the cable design.

CABLE CONSTRUCTION

Optical fibers: Singlemode and multimode tight fibers, with tight buffer coating.

Reinforcement: Either aramid yarn or fiber glass is wound around the tube to provide physical protection and

tensile strength, with added fire protection.

Inner Sheath(optional): Thermoplastic PVC compound type LTS3 as per BS 7655-6.1

Ripcord(optional): An optional ripcord can be located under the outer sheath to facilitate jacket removal.

Armouring(optional):

STA: Corrugated steel tape armour

SWB: Steel 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.

Physical AND THERMAL PROPERTIES

Temperature range during operation (fixed state): -20°C - +60°C

Temperature range during installation (mobile state): 0°C - +50°C

Minimum bending radius: 10 times the outer diameter for unarmoured cables

20 times the outer diameter for armoured cables
