Application fit

Is SY / YSLYSY right for your machine?

SY / YSLYSY is built for machine-shop floors, metalworking lathes, bottling plants and heavy factory installations where hot metal swarf, foot traffic or abrasion would cut an unarmoured YY cable, while retaining Class 5 flexibility.

Fixed installation

Suitable

Exposed machine-tool drop leads, metalworking conveyors, foundry auxiliaries and industrial plant floors.

Trailing & towing

With conditions

Handles flexing and repositioning under mechanical stress, but not high-tension reeling.

Use S07BQ-F Reinforced

Energy chain / drag chain

Not suitable

Galvanised steel wire braid is for mechanical armouring, not continuous drag-chain cycling.

Use JZ-500-PUR

VFD inverter to AC motor screened feeder

Not suitable

Steel wire braid has higher high-frequency impedance than copper; use CY / YSLCY for EMC shielding.

Use CY / YSLCY Screened

FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

What does the 'SY' or 'YSLYSY' cable designation mean?
In German VDE / European cable codes, YSLYSY (commonly called 'SY') denotes a PVC-insulated ('Y'), special control ('SL'), PVC inner-bedded ('Y'), galvanised steel-wire-braided ('S' = Stahldrahtgeflecht) and transparent PVC oversheathed ('Y') flexible control cable.
Why does SY / YSLYSY have both an inner grey sheath and a clear outer sheath?
The extruded grey PVC inner bedding cushions the insulated cores against the steel wires so the braid cannot abrade the core insulation during flexing, while the transparent PVC outer sheath seals the galvanised steel braid against cutting fluids, moisture and corrosion while leaving the armour visible for inspection.
Can the galvanised steel wire braid (GSWB) be used as the sole protective earth conductor?
No. Under BS 7671 and DIN VDE 0100, the galvanised steel wire braid on SY cables is a mechanical armour layer rather than a primary protective conductor. Always select the '-JZ' version and use the internal green-yellow copper core as the circuit protective conductor (CPC), earthing the steel braid at the gland for supplementary fault protection.
How does SY compare with SWA (Steel Wire Armoured) cable?
Traditional BS 5467 SWA cable uses rigid Class 2 conductors and heavy single round steel wires for fixed underground burial. SY / YSLYSY uses fine-stranded Class 5 copper and a flexible woven steel wire braid, allowing tight routing onto vibrating machine tools and workshop drops.
