SY Cable is an armoured flexible control cable designed for measuring control or regulation under tough mechanical stresses. SY cable uses a galvanised steel braided multicore cable protected by a transparent sheath. Stronger than CY and YY cables, this SY cable is widely used in installations where free movement is required without tensile stresses.

Suitable for internal dry, damp or wet environments, including oil-water mixtures. This cable type is not suitable for outdoor applications.

Available in a wide range of core configurations and cross-sectional area (CSA) sizes, with individual cores of green/yellow and varying numbered black cores. SY control cables are not suitable for fixed wiring applications requiring compliance with the requirements set out in BS7671
