Fire Survival Cables

Fire Survival Cables

The Construction of Fire Survival Cables are Different From the Ordinary Fire Alarm Cables. The Copper Conductor is Wrapped with a Specially Designed Heat Barrier High Temperature Sustaining Tape & Fire Resistant Insulation is Covered over Heat Barrier Tape, Which Resists The Fire to Reach the Conductor Surface. The Cable Continues to Remain into Operation at High Temperatures Like 750°C and 950°C of Various Conditions, Operation and Application.

Circuit Integrity Test & Procedure: As Per BS : 6387: 1994. & IEC 60331-21-31 The Test is Carried out on the Cable Operation on Load and Burning at a Temperature of 650°C 750°C for 2 Hrs or 950°C for 3 Hrs. The Cable is Put on Clamps above the Fire Burner of High Flames. The Power Supply is Connected to one end of the Cable at a Rated Voltage and Load is Connected to other End. Fire Applied for 3 Hrs and During This Period the Circuit Integrity must be Uninterrupted

As Per BS : 6387. Resistance to Fire Alone:
Category A) Cables are Subject to Fire at 650°C. for 180 Minutes.
Category B) Cables are Subject to Fire at 750°C. for 180 Minutes.
Category C) Cables are Subject to Fire at 950°C. for 180 Minutes.
Category S) Cables are Subject to Fire at 950°C. for 20 Minutes. (short Duration)

Resistance to Fire with Water:
Category W) Cables Are Subject to Fire at 650°C. For 15 Minute, Then. at 650°C with Water Spray Further 15 Minutes.

As Per IEC 60331-21: Cables are Subject to Fire at 750°C. For 90 Minutes Followed by 15 Minutes Cooling Period.

Resistance to Fire with Mechanical Shock:
BS 6387 ( Category X) Cables are Subject to Fire at 650°C. With Mechanical Shock for 15 Minutes
BS 6387 ( Category Y) Cables are Subject to Fire at 750°C. With Mechanical Shock for 15 Minutes
BS 6387 ( Category Z) Cables are Subject to Fire at 950°C. With Mechanical Shock for 15 Minutes

IEC 60331-31: Cables are Subject to Fire at 830°C. With Mechanical Shock for 120 Minutes
