Description
SY cables are used as an interconnecting cable between fixed and mobile equipment in conveyors, assembly lines, production lines and machine tool manufacture where the galvanised steel wire braid armour gives excellent mechanical protection.
Constructed with flexible fine-wire copper conductors, PVC insulation, a galvanised steel wire braid (GSWB) inner layer, and a clear PVC outer sheath, this 3 core 4mm² SY cable combines robust mechanical strength with high flexibility and significant power handling.
The galvanised steel wire braid layer protects the internal cores against physical damage, abrasion, and mechanical stress while allowing the cable to remain far more flexible than standard steel wire armoured (SWA) cable. The transparent PVC outer sheath allows visual inspection of the underlying braid, making it an ideal choice for factory automation, industrial control panels, heavy-duty plant machinery, and mobile power connections.
Sold cut to length per metre to suit your exact project requirements.
