Waveguides are used to introduce all low-current and information cables into the shielded room, as well as cables of the structured cable network. Low current and power cables should be placed in different passive filter packages. They are calculated and manufactured in accordance with the minimum length of the electromagnetic wave to be shielded.

The waveguides consist of a flange attached to the screen and individual elements corresponding to the steel pipes (calculated cross-section and length), which are assembled by welding into a single structure.

They are mounted in specially prepared openings of a wall partition of the screened premise.
