This material is a ready-to-use mu-copper or tinned mu-copper tube through which a cable or bundle of cables can be pulled. If the tube is compressed lengthwise, the diameter expands to simplify the assembly. Therefore a wide range of cable diameters can be shielded with a single tube.

Please note that the tube has to be expanded for larger diameters and that a larger nominal length will then be required (up to twice the length of the cable).
