ZPGU provides local signalling connections within trackside equipment shelters and associated equipment wiring. The cable uses 1.0 mm² class 1 solid copper conductors arranged in twisted pairs, with PE insulation and an inner PE sheath. A tape screen and tinned copper drain wire provide the screening arrangement beneath a PVC or LSZH outer sheath. Pair count and finished diameter determine the space needed at equipment entries.

1.0 mm² solid copper conductors with a nominal diameter of 1.13 mm.
One, two, three, seven and fourteen-pair arrangements in the dimension schedule.
Tape screening with a dedicated drain wire and PVC or LSZH sheath options.
Select the pair count from the circuit schedule and identify the sheath material for the installation. Coordinate screen continuity and drain-wire termination with the equipment design. Use the listed overall diameter for entries and supports, and the 8 times static or 16 times dynamic bend-radius figures when planning the route.
