Enhanced Electron Beam Cross Linked Unarmoured Fire Resistant Cables – FRX 100+

Metro Rail, Airport, Schools, Shopping malls, Cinemas, High-rise Buildings and fire prone areas.
Indoor and Outdoor uses.

Conductor : Plain annealed Copper solid or stranded circular conductor complying with BS 6360 class 5
Tape : Mica
Insulation : EBXL-XLPE
Outer Sheath : EBXL-ZHLS

Flammability : IEC 60332-1 & IEC 60332-3 Categories A, B & C
Resistance to Fire : CWZ of BS : 6387, IEC 60331 & F-2 of BS : 7846
Smoke Emission : IEC 61034 – 2
Acid Gas Content : IEC 60754 -1 & 2, BS EN 50267 – 1 & 2
Special Features :
a) Maintains Circuit Integrity for 3 hours under fire condition.
b) Zero Halogen, Low Smoke and Resistance to flame propagation.
c) Siechem FRX 100+ meets BS 7846 Cat F2 and meets Test requirements as per BS 6387 CWZ, at an enhanced voltage of 600/1000V.
d) Siechem FRX 100+ also meets 60 minute rating (PH60) to BS EN 50200 and a 30 minute rating to BS 8434-1. These tests demonstrate that FRX 100+ also meets the requirements for use in “Standard” installations in accordance with BS 5839-1 : 2002 for fire detection and alarm systems, and Cables with inherently high resistance to attack by fire in accordance with BS 5266-1 : 2005 for emergency lighting.
