Enhanced Electron Beam Cross Linked Armoured Fire Resistant Cables – FRX 400+

Application

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

Technical Data

  • Temperature Range : -15°C to +120°C
  • Rated Voltage (Uo/U) : 600/1000V
  • Test Voltage : 3.5kV/5 min
  • Bending Radius : Upto 8 of Cable X OD
  • Specification : BS 7846 & BS 6387

Features

  • Flammability : IEC 603321 & 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 – 1 & 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 400+ meets BS 7846 Cat F2 and meets Test requirements as per BS 6387 CWZ, at an enhanced voltage of 600/1000V.
  • d) Siechem FRX 400+ also meets 60 minute rating (PH60) to BS EN 50200 and a 30 minute rating to BS 8434-1. These tests demonstrate that FRX 400+ 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.
