The ÖLFLEX® ROBUST 200 4G2.5 connection cable from Lapp is a flexible control cable designed for use in demanding environments. It is suitable for outdoor use and is intended for permanent installation as well as occasional movement without tensile stress. The cable is specifically designed for applications in harsh, oily, wet or dry environments, remaining flexible even at temperatures down to -40 °C. Typical applications include car washes, wastewater treatment plants, composting facilities, and applications in the food industry where high hygiene and cleaning requirements apply.

Applications

The cable is designed for use in industrial environments where high mechanical, chemical and thermal stresses occur. It is particularly suitable for installations that are regularly cleaned using steam jet cleaning or hot water jets, as it is resistant to hot water and steam. The verified resistance to ECOLAB® disinfectants and cleaning agents makes it a reliable choice for food processing and environmental sectors. It also demonstrates high resistance to UV-C radiation (according to LAPP’s internal testing method).

Functions and Features in Detail

The ÖLFLEX® ROBUST 200 4G2.5 features low-capacitance core insulation, suitable for long transmission distances and maintaining signal quality in electrical connections. Core identification is done by colour, enabling easy assignment and wiring. The cable is made of TPE (thermoplastic elastomer) as insulation and sheathing material, ensuring high mechanical strength and chemical resistance. Its high resistance to plant, animal and synthetic fats and oils, including bio-oils and ester-based hydraulic oils, makes it suitable for applications in agriculture, bioenergy and manufacturing technology. It also shows excellent resistance to ammonia compounds and biogas.

Technology Explained Simply

The cable is rated for an operating voltage of 450/750 V, making it suitable for use in industrial power supply systems. The TPE construction ensures high flexibility and durability, even under extreme conditions. Its robust design allows use in harsh environments where mechanical stresses such as friction or pressure occur. The cable is normatively tested for use in fresh water up to a depth of 10 metres and at a water temperature of 40 °C, making it suitable for limited underwater applications.

Compatibility and Accessories

The cable is intended for connecting devices and machines in various industries. It can be used in combination with water-soluble cleaning and cooling agents without impairing cable properties. Use in installations with UV-C radiation is permitted according to Lapp’s internal testing methods. The cable is not specifically designed for particular accessories, but serves as a universal connection cable for various industrial devices.

Installation and Mounting

Installation is carried out by permanent laying, with occasional movement without tensile stress being possible. The cable is flexible and easy to bend, facilitating installation in tight or complex spaces. The use of appropriate cable protection conduits or ducts is recommended to provide additional protection against mechanical impacts.

Operational Advantages

The ÖLFLEX® ROBUST 200 4G2.5 offers a particularly weather-resistant and long-lasting all-weather cable. The high-quality materials ensure a long service life, even under harsh operating conditions. The high chemical resistance reduces the risk of material damage from aggressive media. The cable is therefore suitable for applications requiring high reliability and low maintenance. The low capacitance of the core insulation ensures stable electrical performance over long distances.
