The control cable ÖLFLEX® CLASSIC 110 H 25G1,5 from Lapp is a halogen-free, flexible cable designed for wiring control circuits in machines and plants. It is suitable for medium mechanical stress and is used for fixed installation as well as occasional movement without tensile stress. The cable is designed for building wiring to meet special fire protection requirements and can be used in dry and damp environments. Due to its flexible structure, it is also usable at temperatures down to -30 °C. It is universally suitable for internal machine and plant-wide control circuits and can be temporarily used outdoors, provided the temperature range is observed.

Applications
This cable is intended for use in industrial electrical engineering and building wiring. It is particularly used where high electrical safety and low fire risk are required. Use in dry and damp indoor environments is standard, and temporary outdoor use is permitted as long as temperature limits are observed. The oil-resistant design makes it suitable for environments with low to medium oil contact, for example in manufacturing industry or marine technology.

Functions and Features in Detail
The control cable features an HFFR outer sheath (halogen-free, flame-retardant, flexible material) which is largely resistant to acids and alkalis. Conductor identification is done by numbers, enabling secure assignment of individual conductors during installation. The cable is UL recognised, allowing its use in North America. Additionally, it is certified by DNV for marine use, confirming its suitability for ships and offshore installations.

Technical Explanation
The cable is rated for an operating voltage of 300/500 V and has a test voltage of 4000 V, ensuring high electrical safety. The halogen-free and flame-retardant materials reduce the risk of fire spread, smoke density, and formation of toxic smoke gases in case of fire. The fire behaviour is VDE-tested and complies with EU Directive 305/2011 (BauPVO/CPR), with the exact classification available via article number selection on the LAPP website. The enhanced oil resistance according to DIN EN 50363-4-1 (TM5) as well as UL OIL RES I and OIL RES II protects the cable from wear due to oil contact.

Compatibility and Accessories
The control cable is universally applicable and can be connected with standard cable lugs, plug connectors, and other connection elements suitable for control cables with 1.5 mm² cross-section. Its use in combination with other Lapp products, especially in system solutions for industrial controls, is possible. The UL certification allows use in installations complying with North American safety standards.

Installation and Mounting
The highly flexible design of the cable facilitates handling and installation, especially in tight bending radii and complex routing situations. The cable can be installed without special tools, with conductor identification by numbers ensuring secure assignment. Fixed installation is typically done in cable ducts, shafts, or with cable ties, while mechanical stress must remain limited.

Operational Advantages
The control cable offers high reliability due to its flame-retardant and halogen-free materials, which ensure low smoke emission and low toxicity in case of fire. Oil resistance increases service life in industrial environments. UL and DNV certifications expand the application range in international markets, especially in shipping and North America. The flexible structure enables easy installation and maintenance, thereby reducing operating costs.
