KBS® Cable Fire Protection Coatings
Reliably preventing fire propagation on electrical cables
Electricity is a lifeline for our modern society. But the cables through which it is transported harbor manifold dangers in case of fire!
Electrical cables can, for example, ignite locally by short-circuiting or overheating. Or they may be preheated by a fire of another cause and ignited by direct exposure to flame. Due to the mostly flammable insulations, a fire can make its way along the cable installations through buildings and facilities in no time, endangering life and limb of the people inside. According to literature, a fire can spread along vertical cable routes at a rate of over 20 meters per minute. Our cable fire protection coatings effectively prevent this. This effectiveness has been proven by a large number of fire tests in accordance with a wide range of standards, carried out by recognized and accredited testing institutes.
There are various options and systems on the market for protecting electrical cables against the spread of fire: e.g. the use of special fire-protection cables, cladding made of non-combustible panels, special prefabricated cable ducts against fire from inside and outside, or fire-protective cable bandages. In contrast to all these aforementioned systems, fire-retardant cable coating is clearly the most cost-effective solution.
For this purpose, we offer two systems under our KBS® brand, which differ fundamentally both in their mode of action and in their practical properties.
Ablative coatings, such as KBS® Coating, which has been produced by Grünau since 1969 and now by Wolman Wood and Fire Protection GmbH, act in the event of fire by means of an endothermic reaction. The material contains substances that undergo chemical and physical changes at elevated temperatures under energy consumption. The cable to be protected is cooled as a result. In addition, gaseous substances escape which have a strong inhibiting effect on the flames.
The intumescent cable coating KBS® Foamcoat develops a microporous foam under the influence of fire, which ensures fire protection due to its insulating effect. This system, also known as intumescent fire protection coating - due to its sensitivity to moisture and humidity - is recommended for use in dry, low-moisture environments only.
