Applications Overview

Due to the mechanical strength provided by their galvanised steel wire braid (GSWB), SY cables, including the Veriflex SY PVC cable, are widely used in industrial applications as interconnecting cables in control equipment or machines where they are subjected to medium mechanical stresses. These flexible instrumentation cables can be used in installations where free movement is required without tensile stresses and without forced guidance systems.

SY cables, also known as armoured flexible control cable, shielded flex, or simply armoured flex, are strong and durable cables suitable for internal dry, damp or wet environments (including oil-water mixtures), and can be used outdoors when protected against direct sunlight. They are also referred to by their constructional reference: YSLYSY cables for the PVC sheathed variation.

The voltage rating for these shielded flexible multi-core control cables is 300/500V.

The grey oversheath SY flex cable with UL and CSA approval tends to be used on equipment intended for export to the North American market.

The clear oversheath of the Veriflex SY PVC cable allows the visual detection of any signs of deterioration, damage or corrosion.

SY cable standards

SY control cables are manufactured to VDE0250, the German national standard that has become internationally recognised as the benchmark for cables, wires and flexible cords for power installations for process and automation equipment and applications in manufacturing plants. Our technical team in The Cable Lab conduct extensive tests on our SY cable portfolio to ensure that our stockholding meets the designated standards and performance requirements.
