The ÖLFLEX® CLASSIC 110 H 3G1.5 control cable from Lapp is a flexible, halogen-free cable designed for use in industrial and building installations. It is designed for medium mechanical stress and is suitable for fixed installation as well as occasional movement without tensile stress. The cable is supplied in a length of 100 meters and is universally applicable for wiring machine-internal and cross-system control circuits. Due to its high flexibility, it is easy to handle and install.

Applications
This cable is suitable for building wiring, especially when special fire protection requirements must be met. It can be used in dry and damp environments and is temporarily suitable for outdoor use, provided the temperature range is observed. The operating temperature ranges up to -30 °C, enabling flexible use in colder environments. The HFFR outer sheath is largely resistant to acids and alkalis, expanding its use in chemically demanding environments.

Functions and Equipment in Detail
The control cable features wire identification by numbers, which simplifies the assignment of individual conductors during wiring. The cable is oil-resistant according to DIN EN 50363-4-1 (TM5) as well as UL OIL RES I and OIL RES II, making it suitable for applications in environments with oil or grease contact. The materials are halogen-free and highly flame-retardant, reducing the risk of fire spread, high smoke density, and toxic smoke gases in the event of fire.

Technology Explained Simply
The cable is equipped with an HFFR outer sheath (halogen-free, flame-retardant, robust material) providing high mechanical and chemical resistance. The test voltage is 4000 V, ensuring high electrical safety. The operating voltage is U0/U: 300/500 V, sufficient for typical control applications in industry and building construction. UL certification allows use of the product in the North American market. The fire behavior is VDE-tested and classified according to EU Directive 305/2011 (BauPVO/CPR), with exact article number selection available on the LAPP website.

Compatibility and Accessories
The cable is designed for use in machine and plant control systems and can be connected with standard connectors and plugs suitable for control cables with a 1.5 mm² cross-section. DNV approval enables use in marine applications, with specific requirements of the respective maritime authority to be considered.

Installation and Mounting
The highly flexible design of the cable simplifies installation, especially in tight or complex routing situations. The cable can be installed without additional tools or aids, provided the guidelines for mechanical stress and temperature range are observed. Fixed installation typically occurs in cable ducts, shafts, or conduit, with occasional movement without tensile stress permitted.

Operational Advantages
The use of halogen-free and flame-retardant materials improves safety in the event of fire. High flexibility and oil resistance increase the cable's service life in demanding environments. UL certification and DNV approval expand the application range internationally, particularly in industrial and marine sectors. Easy handling reduces installation time and costs.
