Flame Retardant Low Smoke Cables

Fire is one of the major hazards to life and property. And electrical cables are perhaps one prime sources of generation and propagation of fire. Protection of cables against fire is therefore an important and primary consideration is in the design and manufacture of cables. Scientists and Engineers all over the world have been seriously concerned, about behavior of electrical cables under fire. Extensive studies and rigorous research into materials and construction of cables has led to the development of fire retardant cables.

In the event of fire the major reasons for destruction and loss are fire propagation emission of corrosive gases and formation of dense smoke KAYDOUR FRLS Cables offer effective resistance against propagation of fire and do not emit corrosive gases and smoke generated during fire of negligible amount . |

Major Areas of Application |
 |
|
1. Power Stations and Factories where
a large group of cables are used.
2. Public Premises Like Hospitals, Multistoried
buildings, Super Markets, Theaters, Cinemas,
Airports etc. where there is always a large
concentration and movement of people.

Kaydour Fire Retardant Cables by
virtue of their characteristics offer following
advantages |
|
1 Non -propagation of fire reduces
risk of life and property.
2 Absence of non-corrosive gases.
Corrosive gases by themselves or when combined with
atmospheric moisture or with water from fire
fighting appliances produce highly corrosive acids
which damage plant, machinery and equipment .
Emission of non-corrosive gases help to prevent such
extensive damage resulting in large savings.
3 Reduced emission of dense smoke
In enclosed or less ventilated areas emission of
dense smoke may prove a major handicap affecting
visibility and evacuation operations. Low smoke
emission from cables assures adequate indoor
visibility and helps in easy accessibility to the
seat of fire, and effective fire -fighting
operations and prompt evacuation.
