Abesco Fire Clamp Cable Transit – The latest fire stop barrier in the EDP Europe Structured Cabling Protection Range.
The Abesco CT120 & CT240 Fire Clamp Cable Transit pathways are fire stop barriers designed to prevent the spread of fire and smoke from one compartment to another where electrical, data and communication cables penetrate through separating walls and floors.
The Abesco CT120 Cable Transit range consists of square and round models, each model being made up of a steel sleeve containing a heat reactive intumescent material. The integral hinged top on the unit allows the Abesco CT120 fire clamp to be easily installed around existing cables providing an excellent retrofit option. Foam seals are installed at both ends of the cable transit to prevent smoke passing through the unit.
Abesco mounting flanges provide a quick and easy method of installing single or multiple CT120 fire clamp cable transits into walls and floors with various sizes of mounting flanges available, including flanges that will accommodate up to six square CT120 fire clamp devices.
When the CT120 fire clamp cable transit is exposed to temperatures of approximately 149°C (300°F), the graphite based intumescent material begins to expand rapidly to form a solid insulating char plug, which effectively closes and seals the CT120 fire clamp cable transit and prevents the passage of fire and smoke through the fire rated wall or floor.
Abesco fire clamp cable transits can be used as effective fire stop barriers in a wide range of buildings and are commonly found in banking & finance buildings, data centres, TV & media studios, apartment buildings, hotels, office blocks, hospitals, airports, retail centres etc.
Cable capacity depends on which CT120 cable transit is being used and the diameter of cable installed, but as a guide with the 102mm (4”) square CT120 cable transit it is possible to install approximately 8 x 35mm cables and up to 1,155 x 3mm cables.
The CT240 fire clamp cable transit provides the same fire stop protection as the CT120 but in a larger rectangular unit. Making it possible to fit around larger cable bundles, as well as making it easier to separate cable runs for better cable management.
