Fire Survival Cables makes the rescue mission a lot easy to execute. Our fire survival cables have the unique ability to extend functionality for circuit and data integrity in extreme fire situations. These cables are made from inorganic materials that do not burn, emit smoke or gas and survive harsh fire explosions. These cables are developed for life-critical situations and are in accordance to fire management systems.
For the transmission of high currents from the electric welding machine to the welding tool. Suitable for flexible use under rough conditions, on assembly lines and conveyor systems, in machine tool and motor car manufacturing, ship, building, for manually and automatically operated line and spot welding machines.
- Grade 1: Remains operational up to 30 minutes when subjected to Flame
- Grade 2: Remains operational up to 180 minutes when subjected to Flame
FIRE! THE UNBEARABLE HAZARD
Fire is one of the most destructive acts, either of nature or mankind and destroys thousands of lives and crores of rupees worth of properties and data.
No Country however advanced, is free from the ravages of fire.
Data reveals that cables are the major causes of fire worldwide.
WHAT CHARACTERISTICS OF CABLES
ARE IMPORTANT IN A
Any cable used in public buildings or in hazardous areas in industries should not have any danger to public lives and properties. The danger is caused through acid gas emission during fire. The cable should be self-extinguishing i.e. should not continue to burn once the source of fire is removed and neither propagate fire any further. Even while burning, the smoke produced should not obstruct the escape and visibility by obscuring emergency lightings and exit signs.
ADVANTAGES OF FIRE
Traditionally fire resisting cables such as MICC (Mineral Insulated Copper Clad) Cables have been used as "Fire Survival Cables". These cables are very expensive to manufacture and install.
Of late a new concept in this field has been developed by MEM which has special Insulation of Glass mica tapes with Elastomeric / Thermoplastic compound and Sheath of "LSZH" which makes the cable "FIRE SURVIVAL".
The Advantages are:
- Zero Halogen, No Corrosive gases
- Flame Retardance
- educed Fire Propagation
- Minimum Smoke Emission
- Longer lengths production
- Easier to install
- Easier to join
- Do not require high degree of skill to install them
- More COST EFFECTIVE design
PROPERTIES OF DIFFERENT SHEATH MATERIALS
• Normal PVC Sheaths (ST-1)
These Cables propagate flame and emits dense fumes & toxic acid gas and Chlorine on burning.
• Flame Retardant Sheath (ST-2 FR)
These Cables do not propagate flame and are self extinguishing. However emits dense fumes, toxic acid gas and Chlorine on burning.
• Flame Retardant Low Smoke Sheath (FRLS)
These Cables do not propagate flame and emit low amount of smoke and fumes. However, emits acid gas on burning.
• Low Smoke Zero Halogen Sheath (LSZH)
These Cables do not propagate flame, emit low amount of smoke and very negligible amount of acid gas on burning.
FIRE SURVIVAL CABLES TESTED AS PER IEC-331
Sample length of 1-2 metres of Cable is subjected to minimum of 3 hours of continuous flame whose temperature is set as per IEC-331 with distance of about 75mm between cable sample and burner. Cable is connected to Test Voltage / Rated Voltage and the cable sample is rechecked after 12 hours. No Voltage failure is observed.
