Electrical system penetrations

When selecting the appropriate fire protection for electrical system penetrations, it is necessary to pay attention to the following factors:

the size of the holes;
the type and size of the electrical system (single cables, cable bundles, cable route penetrations, busbars);
the type of partition (e.g. light or solid walls, ceilings); and
the thickness of the partition.

Due to the extensive possibilities of combination of the above-mentioned factors, we make electrical system protections using Promat, Hilti, Alfaseal, K-FLEX, and Würth technologies, which provide a wide range of applications and are characterized by the highest quality.
