fire protection coating for cable

FlameGuard CP
Intumescent fire protection coating for combustible single & bunched electrical cables
and cable trays

Long runs of unprotected, PVC or plastic rubber sheathed combustible cables, usually supported by vertical or horizontal cable trays and holders, are prone to rapid fire spread and excessive damage. Unprotected cables burn & propagate fire after only a few minutes of exposure to fire. Power current for vital control functions, supplies and services fails very quickly. Burning cable sheaths carry the fire rapidly forward as fast as 20 meters per minute. They gives off aggressive vapors. The cable trays, if not protected, are exposed to the risk from melting and collapsing. Cables, cable trays and holders protected with FlameGuard CP help prevent damage or keep it within reasonable limits.The time that elapses before the current fails is increased many times. The indirect damage from cable fires (fire travel, breakdowns, corrosion resulting from harmful gases affecting sensitive instruments) is generally greater than the
f ire damageinitially visible.

FlameGuard CP is a water-based intumescent coating which is designed to prevent ignition, flame spread & smoke emission along the jacketing of electrical (or other) cables and to provide a thermal barrier for protection against heat damage. FlameGuard CP will also prevent a short circuit within an electrical cable from starting a fire and will help identify the location of such a short circuit by forming an intumescent char at the spot. The coating can be applied to grouped cables or single cables.When exposed to flame or to a temperature above 175ºC, the coating forms a protective intumescent char. (This char should be removed completely and clean cables should be recoated if intumescences should occur). The coating foams up under the effect of heat to form an insulating layer.There is no sub sequent burning of protected cables after the direct effect of fire has been halted. 

The thermal conductivity of a FlameGuard CP coating that has not foamed is about the same as that of a plastic cable sheath, which means that the higher temperature of the conductor is raised only insignificantly in cables protected with FlameGuard CP. As only a relatively thin coating is needed, it allows radiation of heat from cables during operation. The current-carrying capacity remains virtually unchanged. The cured coating is flexible and adapts to the usual movements and bending without flaking. Its premium latex binder system is totally resistant to water and will not re-emulsify after drying. FlameGuard CP reduces the spread of flame in cable runs and prevents the emission of hydrochloric gases in cable fires. The release of hydrochloric acids vapors is slowed down considerably.Acid vapors that are released are neutralized.The upgradation of existing cables to the highest grade of f ire safety is possible with the coating of FlameGuard CP. Additionally the thin film coatings will maintain circuit integrity to small diametrical cables in restricted applications. The coating of the entire length of cables to maintain the power supply to important equipment while data are being saved or a fire extinguished (recommended dry film thickness 1.6 mm). Partial coating of cables (4 m length @ every 10 m interval, recommended dry film thickness of 1.6 mm) to prevent f ire from spreading along cable runs.The cable joints and around cable crossing should be coated at 1.5meteronboth sides of joints.
