The control cable ÖLFLEX® EB 4X1.5 from Lapp is a flexible cable designed for use in industrial applications, particularly in machine and plant engineering. It is designed for moderate mechanical stress and is suitable for fixed installation as well as occasional movement without tensile load. The cable is supplied in a length of 100 metres and is intended for use in dry, damp, and wet environments, including outdoor use, provided the temperature range is observed. The PVC outer sheath is resistant to acids and alkalis and conditionally oil-resistant, which expands its application possibilities in various industrial environments.

Applications

The ÖLFLEX® EB 4X1.5 is specifically designed for use in equipment, machines, and plants with the intrinsic safety protection type 'i'. It is suitable for intrinsically safe circuits in accordance with standards IEC 60079-14, EN 60079-14, and VDE 0165 (Part 1). This protection type ensures that the cable can be used in explosive atmospheres without creating an ignition source. Therefore, the cable is suitable for applications in the chemical industry, mining, or petrochemicals, where high safety requirements apply.

Functions and Equipment in Detail

The cable features core identification by numbers, enabling simple and secure assignment of cores during installation and maintenance. The construction is flexible to ensure easy installation and bending capability. The small outer diameter allows space-saving installation, particularly in narrow installation shafts or when installation cross-section is limited. The cable is manufactured in blue, which facilitates visual distinction from other cables.

Technology Explained Simply

The control cable is rated for an operating voltage of U0/U: 300/500 V, making it suitable for use in many industrial control and signal systems. The PVC sheath provides good protection against external influences such as moisture, mechanical stress, and chemical exposure. The cable’s properties meet the requirements of EU Directive 305/2011 (BauPVO/CPR), ensuring classified fire behaviour. The exact classification can be selected via the LAPP website using the article number.

Compatibility and Accessories

The ÖLFLEX® EB 4X1.5 is designed for use in systems requiring intrinsic safety protection type 'i'. It can be used in combination with other components for intrinsically safe installations, such as switching devices, sensors, or control units that also feature the protection type 'i'.

Installation and Mounting

The cable is intended for fixed installation and can be used for occasional movement without tensile load. The flexible construction facilitates installation, especially in narrow or complex installation situations. Core identification by numbers supports correct assignment during mounting. Installation must comply with the specified temperature ranges and requirements for the application site, particularly in explosive atmospheres.

Operational Advantages

The ÖLFLEX® EB 4X1.5 offers high reliability in industrial applications due to its chemical resistance and mechanical robustness. The cable’s properties enable safe use in explosive atmospheres, increasing operational safety. The small outer diameter reduces space requirements during installation, which is particularly advantageous in existing plants. Clear core identification simplifies maintenance and fault diagnosis.
