Abstract
For protecting electrical installations against electromagnetic interferences and especially against over-voltages as can for instance occur as a consequence of lightning strikes, electrical lines provided between individual electrical apparatus are laid in a flexible hollow tubular member having an electrically conducting surface and at least one separation or division in its longitudinal direction. The hollow member is also provided with an undulated profile. The hollow member can be designed either as divided tubular sections or as cable channels or ducts provided with a covering member.
