Other influential sources have demonstrated that for the last 50 years. 2005).Fire Resistant Cables “The Last Cable Standing” Fire: a serious problem Fires have a high cost in terms of loss of human life and of damages to plants and structures. Research studies in this field state that the most commonly identified cause of death from a fire accident is being overcome by gas or smoke (Department for Communities and Local Government . Cavicel.Fire Statistics. over the last few years. thus seriously complicating the escape from fire. the average time from ignition of a fire to flashover has gone from 15 minutes to 3 minutes. Cavicel has been present for years onto the market with its own products and its own experience. About a third of fires originate inside buildings. the companies have strongly invested in design and development of insulation material and of cables granting the best performances in case of fire. This is the reason why.formerly ODPM . in terms of both signal interruption and fume emission that could prevent the evacuation or the rescue. being hidden in walls or below the floor.

The security of our cables during a fire Cavicel has started designing and manufacturing fire resistant cables in the first 70s. There are a lot of problems to handle. A reliable company. To improve as much as possible the research and development activity. it studied halogen free special compounds having very low fume development. and we have always worked closed to our customers to understand the real needs. When you then have to choose products that must safeguard systems and human lives. and this is why we work together with our customers to deepen all the problems. including the fire resistant cables FIRECEL that are installed in over 30 countries. Cavicel has equipped itself since many years with a fire test laboratory capable to carry out tests according to several international standards. skyscrapers. Cavicel is present onto the market with a wide range of products. The study has then included the optic fibres and in 1999 Cavicel deposited a patent covering fire resistant fibre optic cables. but run for kilometres around us. In 1983 the first patent covering an enhanced flame resistant cable had been deposited and the manufacturing of special products for specific requirements had been enlarged.Fire Resistant Cables CAVICEL When talking about safety. chemical and petrochemical plants. that quite often cannot be seen. Our cables installed in more than 50 countries say that we have the right knowledge and experience in approaching the market. Before that. when the relevant norms were not defined yet. undergrounds. The right Partner is important to CAVICEL and this is why we put our experience at customers’ disposal. Cavicel has then used these products in the manufacturing of its fire resistant cables. We know the problems that a fire could cause to the cables. with a long experience and careful to technology evolution.

The most popular screen is: Aluminium/polyester tape with a tinned copper drain wire or earth conductor Following screens can also been used. stranded or solid. when required: Copper/polyester tape with a tinned copper drain wire. This type of screen presents a lower electrical resistance. Screening Screens are often used in instrumentation cables to prevent or reduce possible interference in cables that can be caused by the following reasons: ■■ Cross-talk from adjacent pairs or triples. or a drain wire. 0. it allows the use of several insulation materials since the fire resistance is guaranteed by the tape. ■■ in presence of corrosive atmosphere. for a better screen effect Bare copper braid for electromagnetic interference or when the cable is subject to movements Aluminium/polyester or copper/polyester tapes normally have a total thickness from 25 to 100 µm. same cross section of the other cores.Fire Resistant Cables Construction and General Information Insulation The most widespread technologies to guarantee the electric cables connection integrity during a fire are currently the following: ■■ ceramified silicone-rubber ■■ mica-glass tape and cross-linked polyolefine The taping with mica tape is the most typical solution. according to cable specifications. 6 .

Fire resistance Fire resistance means that the cable or the installation where the cable is installed is capable to continue to operate even in case of fire for a specific period of time (from 30 to 180 minutes).

In some countries. it is important though that the required performance are clear. Reaction to fire propagation Cables can be a critical vehicle for the fire transmission since they run for long tracts. in fact. without halogens (corrosive gases) and that do not develop toxic gases in case of combustion. by limiting the fire propagation and by reducing fumes and gases that are developed by the combustion and that cause severe damages and human lives losses. The other characteristics can be defined as “passive”. in this case. the characteristics of corrosive gases absence is missing. Normally two characteristics are checked: non propagation of flame on a single cable alike the wiring and the non propagation of flame on more cables assembled as a bunch. This term indicates materials that are properly formulated to guarantee. CAVICEL uses high self-extinguishing materials and realizes constructive solutions that contrast the flame propagation. could also be referred to PVC. Non propagation of fire Smoke Density Acid Gas Emission Cavicel. Other acronyms are used.Emission of fumes and acid gases The first aspect can be considered as “active” since the cable continues to perform its main function: transmit power and signals even during the fire. Conducting Value 9 . It must be considered.Non propagation of fire . as generally happens for electric installations. for instance.Standards at a glance Behaviour to the fire of the electric cables The behaviour of the electric cables in case of fire can be evaluated according to various aspects: Fire resistance . besides the high self-estinguishing characteristic. some of which are registered. the acronym LSF (Low Smoke and Fumes). Emission of fumes and acid gases CAVICEL always uses LSZH (Low Smoke Zero Halogen) sheaths for its FIRECEL cables (unless when specifically prescribed because of special working conditions). not making any reference to halogens. that most commonly identified causes for death from a fire incident are due to gas or smoke. that. also a low emission of clear fumes. even in vertical ducts that could behave as chimneys and therefore propagate the fire even in other areas. A term which is not too clear is. but of primary importance.

This standard is related to cables included in BS 7346-6. The oven reaches a temperature of 920°C and this causes the cable combustion. Currently it is divided in more parts that describe the test modes.Methods of test for assessment of the fire integrity of electric cables. Mechanical shocks are applied to the conduit containing the cable. The cables can be tested in different conditions. This standard is foreseen by BS 5839-1:2002 standards and is an extension of the test conditions according to BS EN 50200 standards.

Determination of the amount of halogen acid gas. even though this too is superseded by now. The previous standards related to fume emission measurement were: BS 7622-1:1993 (SUPERSEDED) . by having them bubbling in a solution that is then titrated. BS EN 61034 . This standard is no longer in force and is replaced by the BS EN 61034-1:2005. In this case the standard allows to calculate a weighed average of the measured value of pH.
