Fire Resistant Cables The Last Cable Standing CABLES VS FIRE Fires have a high cost in terms of loss of human life and damages to plants and structures. Fire is the major cause of destruction, but we must consider that one of the main causes of death are the inhalation of toxic gas that develop and the presence of dense smoke, interfering with the identification of escape routes. It has to be kept into consideration, then, that even the most sophisticated alarm systems or emergency systems can be useless if their performances are compromised by the destruction of the cables caused by the fire....

Fire Performance CABLES HAVE TO BE PROPERLY DESIGNED, MANUFACTURED AND ALSO TESTED. The tests are part of R&D, an extremely strategic activity for a Company and this is the reason why CAVICEL has invested in this field. You can find here the main tests concerning the behaviour of cables under fire conditions, and our main test equipments. It is important to verify all required performances and give the customers the full compliance to the requirements. CAVICEL is proud of its own laboratories and customers are always welcome to visit them.

Fire Resistant Cables FIRE RESISTANCE Cavicel Fire Laboratory BS 6387 Following tests are carried out to verify if a cable is capable of maintaining circuit integrity under fire condition, fire with water, and fire with mechanical shocks. During the tests the cables are maintained at their rated voltage. ► Fire Resistance (CAT. A B C S) The cable is exposed to fire at the specified temperature and time. ► Fire and Water Resistance (CAT. W) The cable is exposed for 15 minutes to flame at 650°C and for additional 15 minutes to fire and water spray. ► Fire Resistance with Mechanical Shocks (CAT....

Fire Resistant Cables FIRE AND FLAME PROPAGATION Cavicel Fire Laboratory BS EN 60332-3 IEC 60332-3, CEI 20-22/3 Fire propagation test on bunched cables Samples of cables 3,5 m long in quantities required by standard are installed on a ladder inside a metallic cabinet. They are subjected to the action of a flame at 750°C for a specific time (20 or 40 minutes). Cables must not burn for more than 2,5 m. BS EN 60332-1 IEC 60332-1, CEI 20-35/1 BS EN 60332-2 IEC 60332-2, CEI 20-35/2, for small diameter cables Flame Propagation Test on a Single Cable A 60 cm long sample of cable is vertically fixed...

Fire Resistant Cables GAS EMISSION Cavicel Fire Laboratory Each non metallic material of the cable (—1.0 g) is burnt into a tube furnace up to 800 °C. A controlled air flow rate absorbs the generated gases in a appropriate solution. The tritation of the solution allows to determine the developed hydrochloric acid (HCl) amount. BS EN 60754-2 IEC 60754-2, CEI 20-37/2-2 ► Gas Corrosivity This test allows estimation of corrosiveness against metals of gases released when cables burn. Materials composing the cable are burnt into a tubular oven with temperature higher than 935 °C. A controlled air flow...

Fire Resistant Cables SMOKE DENSITY Cavicel Fire Laboratory BS EN 61034-2 IEC 61034-2, CEI 20-37/3 ► Smoke Density In a 3 m cube metal cabinet, samples of cables are burned by 100 cm3 of alcohol contained in a metal tray. A photometric system is based on a light source and a photocell placed horizontally in the mid vertical plane of the cube, at height of 2.15 m. Absorbance or light transmission are measured.

CONSTRUCTION AND GENERAL INFORMATION Sheath To optimize the behaviour in case of fire, the sheath is made of LSZH (Lows Smoke Zero Halogen) materials since, thanks to that, fire is not propagated, toxic or corrosive gases are not developed and a minimum quantity of white fumes are emitted. Other materials can obviously be used in case of specific installation requirements, such as: PVC, for example, where a higher resistance to oils and chemicals is required (but this material contains halogens, so it emits acid gas and smoke). PE, when a higher resistance to water and moisture is required (this...

Conductors Conductors can generally be according to EN 60228: CLASS 1 CLASS 2 CLASS 5 solid stranded flexible Type of conductors are chosen according to electrical characteristics, required flexibility, type of connection systems or specific installation conditions, for example: in presence of vibration or movement or reduced bending radius it is preferable class 5 flexible conductor, • class 1 solid conductor is preferable for permanent installation, crimping termination, • in presence of corrosive atmosphere, high temperature or to facilitate the soldering it is preferable tinned conductor....
