The CIB installations require shielded cables with twisted pairs, with the wire diameter of at least 0.6 mm, preferably 0.8mm, e.g. the JY(St)Y1x2x0.8, or YCYM 2x2x0.8.
The J-Y(St)Y1x2x0.8 cable:
The cable is designed for internal fixed wiring in communication, measuring and control technology. It is suitable for installations where lines are expected to run in parallel (the power and communication lines). The wire insulation is made of PVC. The wires are twisted in pairs, the cable core is wrapped up in foil, the static screening is made of alluminum-laminated plastic film with copper drain wires, the outer sheath is made of PVC.
