Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
162 words
An arrangement for interconnecting electrical apparatus for protecting same against electromagnetic interference due to over-voltages and lightning effects, said arrangement comprising a plurality of electrical lines for connecting individual electrical apparatus, a hollow elongated generally tubular member surrounding the electrical lines along substantially their entire length, said tubular member having an electrically conducting surface forming electrical shielding of the lines and being fully divided and fully separable into two halves in its longitudinal direction, said tubular member having an undulated profile and being flexible, one of the two halves having spaced plug connections integral with and extending along at least one of its longitudinal edges, the other of the two halves having spaced receptacle connections integral with and extending along at least one of its longitudinal edges, said plug and receptacle connections being locatable opposite to one another when the two halves are assembled, said plug and receptacle connections forming detachable snap-in fasteners for assembling and disassembling said two tubular member halves.
Claim 2
Dependent Claim
162 words
