The control cable ÖLFLEX® ROBUST 210 4G2,5 from Lapp is a flexible, weather-resistant cable designed for use in demanding environments. It is suitable for wiring internal machine and plant-wide control circuits and is specifically designed for outdoor use. The cable is intended for fixed installation and can be moved occasionally, provided no tensile stress is applied. Due to its robust construction and the use of high-quality insulating and sheathing materials made of TPE (Thermoplastic Elastomer), it features a long service life and high reliability. Conductor identification is done by numbers, which facilitates clear assignment of the conductors.

Applications

The cable is universally applicable in dry, wet, rough, and oily environments. Typical application areas include car washes, wastewater treatment plants, composting facilities, and applications in the food industry. It is particularly suitable for environments where water-soluble cleaning and cooling agents are used, and it has proven resistance to ECOLAB® disinfectants and cleaning agents. The cable is also suitable for applications with UV-C radiation, according to an internal test method by Lapp.

Functions and Features in Detail

The ÖLFLEX® ROBUST 210 4G2,5 features low-capacitance conductor insulation, suitable for long transmission distances and ensuring minimal signal distortion. The cable is resistant to hot water and steam, making it suitable for frequent steam cleaning. It exhibits excellent resistance to a wide range of chemicals, including ammonia compounds and biogas, as well as plant-based, animal-based, and synthetic fats and oils, including bio-oils and ester-based hydraulic oils.

Technology Explained Simply

The cable is rated for an operating voltage of U0/U: 300/500 V, making it suitable for many industrial control applications. The insulation and sheathing are made of TPE, a material known for its flexibility, chemical resistance, and weather resistance. The temperature resistance extends down to -40 °C, enabling flexible use even under extreme cold conditions. The cable is normatively tested for use in fresh water up to a depth of 10 meters and a water temperature of 40 °C.

Compatibility and Accessories

The cable is available in various variants, with the specified version 4G2,5 (four conductors each with a cross-section of 2.5 mm²) representing the specific configuration. Compatibility with various industrial environments, particularly in the food and wastewater sectors, is ensured by its chemical resistance and resistance to cleaning processes.

Installation and Mounting

The cable is intended for fixed installation and can be moved occasionally, provided no tensile forces act on the cable. Installation is carried out in the usual manner for flexible control cables, taking into account the mechanical and chemical stresses of the environment. Use in outdoor areas requires careful planning of the installation to fully exploit the cable’s weather resistance.

Operational Advantages

The ÖLFLEX® ROBUST 210 4G2,5 offers high reliability and longevity in demanding industrial environments. Its resistance to chemical influences, high temperatures, moisture, and mechanical stresses reduces maintenance frequency and increases operational safety. The low-capacitance insulation ensures clear signal transmission over long distances, which is particularly beneficial in large-scale plants. The cable is tested for use in fresh water up to 10 m depth and 40 °C water temperature, making it suitable for underwater applications as well.

Protection Class and Environmental Resistance

The cable is designed for outdoor use and shows high resistance to UV radiation, moisture, oil, and chemicals. The TPE insulation and sheathing provide high mechanical strength and weather resistance. The operating temperature range extends from -40 °C up to the maximum values determined by the environment and load. The cable is suitable for frequent steam cleaning, making it especially valuable in the food and packaging industries.
