Low-capacitance core insulation

The ÖLFLEX® ROBUST 210 4X1 control cable from Lapp is a flexible, weather-resistant cable designed for use in demanding environments. It is suitable for fixed installation as well as occasional movement without tensile stress, and is universally used in machine-internal and plant-wide control circuits. The cable is specifically designed for outdoor use and can be employed in dry, wet, oily, and rough environments. Typical applications include car wash plants, wastewater treatment plants, composting plants, and applications in the food industry, where high requirements for cleanability and chemical resistance apply.

Applications

The cable is designed for use in industrial plants that frequently undergo steam cleaning, exposure to hot water or steam, and contact with water-soluble cleaning and cooling agents. It is also suitable for applications with UV-C radiation, according to an internal test method by Lapp. The suitability for use in fresh water up to a depth of 10 metres and at a water temperature of 40 °C is normatively tested. The cable can be flexibly used at temperatures down to -40 °C, making it suitable for climatically extreme conditions.

Functions and Features in Detail

The ÖLFLEX® ROBUST 210 4X1 features low-capacitance core insulation, suitable for long transmission distances and minimizing signal distortion. The cores are numbered for easier wiring and maintenance. The cable is made of TPE (Thermoplastic Elastomer) as insulation and sheathing material, ensuring high mechanical and chemical resistance. The core insulation is resistant to a wide range of chemicals, including ammonia compounds and biogases, as well as plant, animal, and synthetic fats and oils, including bio-oils and ester-based hydraulic oils. Additionally, the cable is tested for resistance to ECOLAB® disinfectants and cleaning agents.

Technology Explained Simply

The use of TPE as sheathing material ensures high flexibility and durability, even under mechanical stress, chemical exposure, and weather influences. The low-capacitance insulation reduces electrical capacitance between cores, which is particularly important for long cables to avoid signal distortion and data loss. The cable is rated for an operating voltage of 300/500 V, making it suitable for most industrial control applications. Its high resistance to steam and hot liquids makes it ideal for plants that require regular hygienic cleaning.

Compatibility and Accessories

The cable is universally applicable and can be used in combination with various control and automation systems. It is particularly suitable for plants using water-soluble cleaning and cooling agents. The wide range of variants allows adaptation to different requirements without requiring special additional components.

Installation and Mounting

The cable is designed for fixed installation and can be used for occasional movement without tensile stress. Its flexible structure facilitates installation, especially in tight or complex plant structures.

Operational Advantages

The robust construction and high resistance to chemical and physical influences ensure a long service life and low maintenance frequency. The cable is particularly suitable for applications where high hygiene and safety requirements apply. Its suitability for a wide temperature range from -40 °C to 40 °C in water enables flexible use in various climatic and industrial environments. The tested resistance to ECOLAB® products and other chemicals reduces the risk of material damage during cleaning processes.

Protection Rating and Environmental Resistance

The cable is suitable for outdoor use and features high weather resistance. The materials are selected to withstand UV radiation, moisture, oil, and chemical influences. The normative testing for use in fresh water up to 10 m depth and 40 °C water temperature highlights its reliability in wet environments. The cable is therefore suitable for outdoor plants as well as in humid indoor areas, particularly in food and environmental technology.

Application-Specific Features

The cable is specifically designed for plants that frequently undergo steam cleaning. Its hot water and steam resistance ensures that the cable maintains its function even under high thermal stress. Use in oily environments is guaranteed by its high resistance to fats and oils. Numbered core identification simplifies installation and maintenance, especially in complex plant structures.
