CABLE PROTECTION

 FlameGuard CP

 

 

 

   

 

 

 

Intumescent f ire 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 f ires (f ire travel, breakdowns, corrosion resulting fromharmful gases affecting sensitive instruments) is generally greater than the firedamageinitially 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 formsa protective intumescent char. (This char shouldberemovedcompletelyandclean cables should be recoated if intumescences should occur). The coating foams up under the effect of heat to form an insulating layer.There isnosubsequent burning of protectedcables after the directeffect of fire hasbeenhalted.
