Fire Resistance Cable

Fire Resistance Cable and fire retardant cable sheaths are design to resist combustion and limit the propagation of flame

Fire Resistance Cable 100M Roll

We supply a full range of Fire Resistance Cable and fire performance cables, often also referred to as fire survival cables, fire–proof cables, or simply fire cables.

Fire-resistant cables

Ire-resistant Flamerex cables from Reka Cables are suitable for applications where power supply needs to be secured, also during a fire. Fire-resistant cables are halogen-free, and do not contain any PVC or spread fires when used in a bundle. The materials used in halogen-free cables are easy to recycle.

Fireproof Cables

Welcome to Caledonian dedicated web site for fireproof cables. Fireproof cables are designed to function properly also during the fire. The emission of smoke in this situation is free from corrosive gas and to help those working towards fire safety in the built environment.

In all fire disasters, fire smoke, heat and toxic fumes are the main obstacles to safe evacuation of a building or area. A major contribution towards overcoming these hazards is the use of fireproof cables having fire resistance, fire retardance, and low smoke and non-halogenated properties.

Caledonian fireproof cables, branded under fireflix (fire resistant LSZH sheathed cables), FIRETOX (fire retardant LSZH sheathed cables) and FIREGUARD (fire retardant PVC sheathed cables) provide the following features:
-Fire resistance
-Long-term circuit integrity in a fire
-Minimum smoke emission
-Flame retardance
-Reduced fire propagation
-Zero halogen

To describe a cable as ‘LSHF’, it must pass two tests: (a) a smoke cube test, which sets a maximum accumulated smoke density produced when burning the cable with a standard fire, and (b) a corrosive and acid gas test where the cable materials are roasted and must give off a maximum of 0.5% acid gas. These tests are both specified in cable standards which include the description ‘having low emission of smoke and corrosive gases when affected by

’. Cables made from PVC or similar halogenated materials are unlikely to pass these tests. A common misunderstanding is that a ‘LSF’ cable means it has only passed the smoke test and not the acid gas test. We prefer to use the ‘LSHF’ designation as it reinforces both requirements.

Fireproof cables are mainly used in the wiring of:
-Fire resistant safety circuits
-Public address and emergency voice communication systems in high-rise building
-Control and instrumentation services in industrial, commercial and residential complexes -High-temperature installation condition
-These are used in the design and installation of fire alarm systems.

UNDERSTANDING THE DIFFERENCE OF FLAME RETARDANT and FIRE RESISTANT CABLES

Whenever public space is planned, ‘planning for the worst’ keeps step.  Fire and disaster planning is painstaking, so it is of the utmost importance that specifiers and contractors understand when to use Flame Retardant and when to use Fire Resistant cable, what the differences are and how the right choices should be arrived at.

Flame retardant cables are designed to resist the spread of fire into a new area. Fire resistant cables are designed to maintain circuit integrity and continue to work for a specified period of time under defined conditions.

Both have an important part to play in preserving the integrity of the environment during a fire incident, and improving the chances of escape and survival.

Tratos’ flame resistant cable meets flame propagation testing BSEN60332, EN50265 and BS 4066

Typical applications for Tratos’ fire resistant cable include public buildings from schools to hospitals, underground and overground railway stations, retail and leisure venues as well as offshore vessels and hazardous environments such as Oil & Gas platforms.

The company can supply a complete range of fire resistant cables to comply with the latest Standards and Codes of Practice covering fire detection, alarm systems, emergency lighting or other vital power supplies.

Tratos has comprehensive modern fire testing facilities on site to ensure cable integrity. Thanks to this facility it can produce cable for international projects that meets multiple nations’ standards.

Tratos Firesafe cables are manufactured in accordance with all the relevant standards: find out more here. https://tratosgroup.com/families/fire-resistant/.

Tratos supplies “standard” and “enhanced” grade cables to suit the actual installation, large or small, simple or complex in accordance with the applicable Code of Practice. Alongside Firesafe cables Tratos offers a selection of accessories including glands, p-clips and saddles in Low Smoke Zero Halogen (LSOH) from stock to suit all Tratos Firesafe cables.

There are important differences between LSF (Low Smoke and Fume) and LSHF (Low Smoke Halogen Free) cables.  LSF is a term used originally by the MOD(N) to describe cables with a high oxygen index, high temperature index CSP sheathing compound. These cables were claimed to have improved performance in fire, and the MOD(N) termed these Low smoke and fume cables. The smoke emission of the CSP sheathing compound was evaluated using the NBS smoke chamber.

Although an improvement over cables sheathed with traditional CSP, unfortunate events in the Falklands war lead to the development of much improved compounds.

In the commercial cable market the term LSF began to be used to cover any cable with a high oxygen index or temperature index coupled with a reduced emission of smoke, including halogenated materials such as PVC, CSP and PCP.

LSHF is not a true technical term, it is one some companies use to describe their Low Smoke Halogen Free cables, while others use their own descriptors such as Low Smoke O (zero) Halogen (LSOH), Low Smoke Zero Halogen (LSZH), Low Smoke No Halogens (LSNH).  Fire safety advances in cable production have had a particular focus around PVC.

PVC & FIRE

Burning PVC gives off poisonous gasses, in particular hydrogen chloride (HCL). When HCL combines with moisture it forms hydrochloric acid; life threatening and corrosive to electronics, metal surfaces and buildings. Zero halogen cables, with their inhibited production of dense black smoke, significantly increase chances of escape.

Low smoke halogen free cables also lower the risk of fumes causing choking and reduce the likelihood of acidic gas damaging electronic equipment.

While LSHF cables emit no more than 0.5% hydrogen chloride during fire tests, some LSF cables are made from a modified version of PVC and can still give off significant levels of dense smoke and hydrogen chloride gas when burned.  They still have a place, but they have no place in public spaces or where equipment will be exposed to damage.

Tratos Testing Facility

As an innovation-driven company working to develop bespoke cable alongside researching the best of next-generation product performance, Tratos felt it was critical to invest in its own on-site test facility – with fire-testing at the top of the agenda.

Its UK & Italy fire-testing facilities are second to none, giving Tratos’ customers cable that is tested against, passes and often exceeds, minimum standards.

The company manufactures the highest quality cable and, because it serves customers worldwide, it has to ensure its products are compliant with international standards.  The test facility handles standard tests for voltage, spark test and resistance, as well as more in-depth tests for elongation, heat shock, shrink back and vertical flame tests.

These tests and measurements are wide ranging, exploring available safe egress (ASET), area burning rate, backdraft, burning behaviour, char, combustion, deflagration, ease of ignition, fire load density, fire resistance, flame spread, linear and mass burning rates, opacity of smoke, oxygen index performance and more.

Tratos’ test facilities include a CPR (BS EN 50399) Test Rig, small scale (Bunsen burner test) BS EN 60332-1, large scale vertical propagation BS EN IEC 60332-3, Smoke density – 3 m3 BS EN 61034  and NBS Smoke Density Chamber, Acid gas emission BS EN 60754, test on gases evolved during combustion of materials from cables.

Determination of halogen acid gas content, Limiting Oxygen Index (LOI) – ASTM D2863 and Flammability Temperature Index (FTI) – ISO 4589-3.  For the detail behind the Standards, find out more, here https://tratosgroup.com/families/fire-resistant/
