FIRE SURVIVAL (FS) CABLES

POWER-FLEX® Unarmoured & Armoured Fire Survival Cables

Power-Flex Fire Survival Cables offer high circuit integrity for installations where certain critical circuits are required to continue to operate in the event of fire. It is highly recommended for use by experts in airports, hospitals, theaters, shopping enclaves, oil and petrochemical plants, pharmaceutical units, thermal and power stations, IT parks, mass transit systems to name a few.

These cables are designed to continue to function and sustain high temperatures for a defined minimum period of time and fire. These cables conform to various BS and IEC specifications such as BS: 7846, BS: 6387 (C,W,Z) and BS: 7211. The performance of the cable under the fire conditions is specified in several international standards listed below:

  • Flame propagation test: IEC 60332-1, BS EN 60332-1
  • Flame spread test: IEC 60332-1, BS EN 60332-3
  • Fire resistance test: IEC 60331, BS 6387
  • Resistance to fire with water: BS 6387
  • Acid Gas emission test: IEC 60754, BS EN 50267
  • Smoke emission test: IEC 61034, BS EN 61034
  • Limiting Oxygen index: ASTM D 2863
  • Toxicity: NES 713

Power-FlexFire Survival Cables maintain circuit integrity in the following category.

  • CWZ C for 950° C +-40° C under test to flame via direct impingement for 3 Hours
  • CWZ W for 650° C under test to flame with direct application of water for 30 Min
