The control cable ÖLFLEX® CLASSIC 110 SY 25G0,75 from Lapp is a flexible cable for use in industrial and machine engineering applications. It features 25 conductors with a cross-section of 0.75 mm² and is designed for an operating voltage of U0/U: 300/500 V. The cable is equipped with a PVC outer sheath, resistant to acids and alkalis, and is suitable for wiring internal machine and plant-wide control circuits. It is universally applicable in dry, damp, and wet rooms and is suitable for moderate mechanical stress.

Applications

The cable is intended for fixed installation and can be moved occasionally, provided no tensile stress occurs. It is commonly used in automation technology, the machine building industry, and plants with control engineering requirements. The cable is used indoors and remains stable in damp and wet environments. The PVC insulation ensures high chemical resistance, particularly against acidic and alkaline substances.

Functions and Equipment in Detail

The control cable features conductor identification by numbers, enabling easy assignment and wiring. The PVC outer sheath provides high mechanical stability and protection against external influences such as moisture and chemical substances. An extruded inner sheath adds extra robustness and improves insulation quality. The steel wire braid offers enhanced protection in situations with increased mechanical stress, for example, during collisions or pressure loads.

Technology Explained Simply

The cable is designed for an operating voltage of 300/500 V, which is sufficient for most control and signal applications in industry. The test voltage is 4000 V, ensuring high electrical safety. The VDE registration number 7030 confirms approval and quality according to German electrical standards. The cable is classified in accordance with EU Directive 305/2011 (BauPVO/CPR), ensuring fire behaviour and safety in building applications. The flexible structure allows easy installation, especially in tight or curved runs.

Compatibility and Accessories

The cable is universally applicable and can be combined with various connectors, cable lugs, and connection elements suitable for PVC insulation. Use in control and signal systems does not require special additional components, as the cable itself provides the necessary electrical and mechanical properties. Combination with other Lapp products, such as protective conduits or cable trees, is possible as long as mechanical and electrical requirements match.

Installation and Mounting

Installation is carried out by fixed routing, and the cable can be moved occasionally as long as no tensile stress occurs. The flexible structure facilitates pulling into cable ducts or conduits. Connections are made using appropriate cable lugs or plug connectors, with conductor identification by numbers enabling secure assignment. Installation in damp or wet rooms is possible, as the PVC sheath provides the required moisture resistance.

Operational Advantages

The control cable offers high electrical safety due to the 4000 V test voltage and a robust mechanical structure thanks to the steel wire braid and extruded inner sheath. VDE approval and CPR classification guarantee compliance with European safety standards. Universal applicability in dry, damp, and wet rooms, along with resistance to acids and alkalis, increases the cable’s lifespan and reliability in industrial environments. The wide range of available dimensions allows flexible adaptation to different requirements.
