LIY(St)CY Signal Cables

The LIY(St)CY cable is a dual-shielded signal cable with a PVC outer sheath, carrying both an aluminum foil and a copper braid shield over PVC-insulated stranded copper cores. It is used to carry low-level analog measurement and data signals in facilities with strong noise sources such as frequency converter drives, welding machines and high-current busbars. In the category, Mekas Kablo, Reçber Kablo and Birtaş Kablo products are sold by the meter in cross-sections such as 2x0.22 mm², 6x1.5 mm² and 8x2.5 mm², including the OZ type with numbered cores from Birtaş. First check whether the noise level in the environment requires a dual shield, then choose the number of cores according to the number of signals and the cross-section according to line length and circuit current. While the foil shield provides a continuous cover against high-frequency interference, the braid shield is effective against low-frequency interference and adds mechanical strength to the cable. LIY(St)CY should not be confused with LI2Y(St)CY PIMF, whose pairs are individually shielded: in this cable the foil and braid form a common shield over all the cores, and the core insulation is PVC.

How to choose LIY(St)CY Signal Cables

The LIY(St)CY cable is a dual-shielded signal cable with a PVC outer sheath, carrying both an aluminum foil and a copper braid shield over PVC-insulated stranded copper cores. It is used to carry low-level analog measurement and data signals in facilities with strong noise sources such as frequency converter drives, welding machines and high-current busbars.

  • Clarify the circuit duty first: power distribution, control, fire safety, Ethernet or analog signal.
  • Compare conductor cross-section, core count, insulation and shielding against the installation route.
  • Switch to the proper cable family early when flex duty, oil resistance, halogen-free jacket or fire integrity is required.
