LIY(St)Y Signal Cables

The LIY(St)Y cable is a signal cable with PVC-insulated stranded copper cores wrapped in an aluminum foil shield with a drain wire, and a PVC outer sheath. It is used in fixed indoor installations for alarm, card access, intercom and building automation signals, and in industrial measurement lines where a shield against external interference is required. In the category, Mekas Kablo, Reçber Kablo and Birtaş Kablo products are sold by the meter in cross-sections such as 2x0.22+0.22 mm², 4x0.50 mm², 6x1 mm² and 10x1.5 mm². Choose the number of cores according to the number of signals, the cross-section according to line length and the permitted voltage drop, and the color-coded or numbered (OZ) core layout according to the terminal block plan. The foil shield wraps the core bundle without gaps; the shield is grounded through the drain wire, written as +0.22 mm² or +0.50 mm² in some product names. Foil-shielded LIY(St)Y is for fixed installations: on continuously flexing moving lines, it is not a substitute for a flexible copper braid shielded cable.

How to choose LIY(St)Y Signal Cables

The LIY(St)Y cable is a signal cable with PVC-insulated stranded copper cores wrapped in an aluminum foil shield with a drain wire, and a PVC outer sheath. It is used in fixed indoor installations for alarm, card access, intercom and building automation signals, and in industrial measurement lines where a shield against external interference is required.

  • 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.
