Arrangement for flue gas sealed laying of e.g. cable through fire protection wall, has sleeve e.g. intumescent material sleeve or plastic sleeve, inserted into punch hole, where elongated molded part is guided trough sleeve

摘要

The arrangement has a sleeve (1) e.g. intumescent material sleeve or plastic sleeve, including an external measurement or an external diameter, which corresponds to a diameter of a flow through punch hole of a fire protection wall. The intumescent material sleeve consists of plastic mass with intumescent additives, and the plastic sleeve consists inner and/or outer intumescent material coating. The diameter of the punch hole is slightly larger than a diameter of an elongated molded part. The sleeve is inserted into the punch hole, where the elongated molded part is guided trough the sleeve.
