LIY(St)2Y Signal Cables

The LIY(St)2Y cable is an outdoor signal cable with PVC-insulated stranded copper cores wrapped in an aluminum foil shield, with a polyethylene (PE) outer sheath. It is used in alarm and intercom connections between buildings, in barrier and gate automation, and on the fixed signal lines of irrigation and environmental systems that run outdoors. In the category, Reçber Kablo's LIY(St)2Y family is sold by the meter in cross-sections such as 2x0.22 mm², 5x1 mm², 6x2.5 mm² and 10x0.50 mm². Choose the number of cores according to the number of signals, the cross-section according to line length and circuit current, and the shield construction according to the noise level in the environment. On stationary outdoor lines, a foil shield gives a thinner cable diameter than a braid shield; next to strong noise sources, the braid-shielded LIYC2Y or the dual-shielded LIY(St)C2Y should be considered. LIY(St)2Y should not be confused with LIY(St)Y: the 2Y at the end indicates that the outer sheath is polyethylene, while a single Y indicates PVC.

How to choose LIY(St)2Y Signal Cables

The LIY(St)2Y cable is an outdoor signal cable with PVC-insulated stranded copper cores wrapped in an aluminum foil shield, with a polyethylene (PE) outer sheath. It is used in alarm and intercom connections between buildings, in barrier and gate automation, and on the fixed signal lines of irrigation and environmental systems that run outdoors.

  • 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.
