Fire Survival cable manufacturer in India

To introduce ourselves – we are in the marketing of Fire Survival / Fire Resistance / Fire Alarm Circuit Integrity (CI) Cables conforming to BS 8519, BS 5839-1, BS 7629-1, BS 7846 F-2 & F-120, BS EN 50200 PH-30, BS EN 50200 PH-60 & BS EN 50200 PH-120 + Annex-E, BS 8434-2, BS 8491:120 mins , BS 6387 CWZ, IEC 60331-1 & 2 all over India.

The advantage of these cables are that they maintain Circuit Integrity even when burning @ 950°C upto 180 mins (replacement of MICC – Mineral Insulated Cables). Whereas, PVC FR/FRLS cables - even in Metal conduits, will fail in a short time as PVC-FRLS cables are FLAME RETARDANT cables and are used only where curbing Flame Propagation in adequate like in Non-critical systems which can fail without causing damage to life and property.

On the contrary, Fire Survival Circuit Integrity (CI) cables are designed to meet the requirements of FIRE SURVIVABILITY i.e. they Survive under fire conditions and retain enough dielectric strength and also carry the rated current at rated Voltage even during burning.

During a fire crisis situation, Circuit Integrity has to be maintained and this can only be achieved by using Fire Survival / Fire Resistant Cables. This broadly relates to the following critical areas:-

    1) Fire Detection and Alarm Systems.     2) Public Address and Emergency evacuation announcement system.
    3) Power supply to Pressurization Fans.     4) Power supply to Smoke Extraction Fans.
    5) Power supply to Emergency Lighting System.     6) Power supply to Elevators.
    7) Power supply to Fire Pumps

Besides, there are other advantages, such as :-
  1) The biggest advantage is that for the price PVC FRLS Cables + MS Conduit, the total cost works out to a figure that is almost equivalent to the vastly superior Fire Survival Circuit Integrity (CI) cables that we are offering.
  2) Labour: Not much labour is required to install these cables since they do not have to pass through a conduit. This becomes a plus point since the requisite skilled (or even unskilled) labour is not available.

In the field of Fire Survival / Fire Resistance cables, it has been our effort to offer world class products after getting proper International approvals/certifications like LPCB, BRE GLOBAL - UK. Fire resistance halogen free cables offered by India Impex have been successfully meeting the complex & changing cabling needs of the Indian & global markets across various sectors.

FAQ

How can Fire Survival Circuit Integrity (CI) cables contribute to Fire Safety?

The primary cause of casualties in an indoor fire is smoke and dangerous emissions, which essentially decrease the chance to escape and amplify the harm to products far behind the burned zone. The contribution of cables is most vital in active and passive security. Low emission cables are the fundamental component of any alarm circuit. The fundamental criteria in the selection of materials are low production of smoke and harmful gases within the event of a fire; make it conceivable to diminish the presence of dangerous gases and to encourage escape. It is essential that the production of dark smoke and harmful emissions is as low as possible amid a fire. The majority of death amidst fire is due to inhaling dangerous gases. It is crucial to encourage secure evacuation to reduce the exposure time to gases while having sufficient visibility. The Fire Survival Circuit Integrity (CI) cables guarantees less darkness by smoke, lower emission of gases and less heat release. A recent recreation was done by one of the most renowned Fire Engineering Universities that demonstrated the critical contribution of cables to emissions and fire escape.

The operation of low emission cables is the same as compared to standard cables. Fire Survival CI cables versions standard cable types - either power or telecom – have indistinguishable electrical properties. They carry the same capacity and current when comparing cables rating and the same working temperature or protocol.

The various terms utilized within the cable industry when alluding to Low Smoke Halogen Free cables can lead to confusion within the market LSZH, LSF, OHLS, ZHLS, etc. The most source of confusion is utilization of the term LSF (Low Smoke and Fume). It is assumed that the LSF abbreviation refers to Low Smoke Halogen Free cables. In any case, it can refer to special grades of PVC cables and it should not hence accept that these cables would be secure to utilize where the security of individuals and equipment is critical.

Cables are not visible to us once installed, but most of the time they are around us. They connect floors and rooms and go through the walls without interference. In the event of a fire, cables are a crucial vector of propagation of fire to the entire building through the cabling system. The sheer volume of cables in modern buildings due to the rapid innovative evolution (electrical appliances, phones, computer connections, etc.) can be astounding. In numerous offices and malls, modern cables are included, for updated IT systems or modern electrical security measures. All these cables act as fuel for a fire. In the Fifties, the average time from the start of the fire to flashover was 15 minutes. Presently deadly conditions can happen after 3 minutes. This change has come around since the rise in plastics in our homes.
