Lapp SY Silflex

Superior Mechanical Protection with Lapp SY Silflex

When your electrical installation requires a high degree of flexibility combined with robust mechanical protection, SY cable is the industry standard. The Lapp SY Silflex range, available at Demesne Electrical, is engineered for use as a control, connecting, and measuring cable in industrial environments. This multi-core PVC cable features a unique galvanised steel wire braid (GSWB) beneath a transparent outer sheath, providing an additional layer of protection against physical stress and abrasion that standard YY control cables cannot offer.

Technical Specifications and Performance

The Lapp SY Silflex range is manufactured to exacting standards, carrying the VDE registration number 7030. One of its standout features is the transparent PVC outer sheath, which allows for immediate visual inspection of the steel braiding to identify any signs of corrosion or internal damage. With a high electrical performance rating and a 4 kV test voltage, these cables ensure reliable signal transmission even in demanding automation settings.

We stock a comprehensive variety of sizes, ranging from 0.75mm to 10mm conductor sizes, with core counts from 3 up to 18. Whether you require number-coded or colour-coded cores for easy identification during installation, the Silflex range provides the versatility needed for complex control and automation projects.

Choosing the Right Cable: SY vs CY vs YY

Selecting the correct cable for your application is essential for safety and longevity. While CY control cables are shielded with tinned copper braid to prevent electromagnetic interference (EMI), SY cable prioritises mechanical strength. In contrast, YY cables lack any braiding and are suitable for applications with minimal mechanical risk.

For installations where the cable may be exposed to moisture or requires secure termination, it is vital to pair your SY cable with professional cable accessories and SWA cable glands. If your project involves routing cables through harsh environments, consider using our flexible conduit systems for an added layer of security.

Applications and Safety Compliance

Lapp SY Silflex is primarily designed for fixed industrial installations but can also accommodate occasional non-continuous movement. It is widely used in conveyor systems, production lines, and machine tool manufacturing. However, it is important to note that standard SY cable is not UV-resistant and should be protected when used in outdoor applications. For those building industrial panels, these cables integrate seamlessly with our range of industrial enclosures and DIN rail terminals.
