Use of variable structure ducts in busbars with fire barriers

Abstract

The use of busbar systems, especially in large and complex structures, has facilitated the installation and use of energy distribution systems. However, the use of busbar systems composes security risks. Busbar modules mounted on the building wall in busbar systems are transferred through the holes drilled in the walls. This situation causes the fire not to be confined during a fire and to spread rapidly to the entire structure through busbar holes. After the installation of energy distribution systems, specialized companies undertake the fire insulation of the holes against fire. However, these companies provide insulation by insulating the outside of the modules passing through the wall. Such an application creates disadvantages. In our country, it is seen that such building materials are not used in most buildings due to the difficulty of installation and the high cost of fire barriers. In the study; A fire barrier system has been developed that encourages the use of fire barriers, increases the endurance time to 3 hours and above, and also reduces the module sales price. Optimum design geometry and construction has been created, durable raw materials have been developed, desired success criteria and international test norms have been provided.
