The ÖLFLEX® HEAT 180 SiHF 2X0.75 cable from Lapp is a heat-resistant silicone cable designed for industrial applications, particularly in machine and plant engineering. It is intended for wiring control circuits operating under high temperatures and in chemically demanding environments. The cable has a rated voltage of 300/500 V and is designed for fixed installation as well as occasional movement without tensile stress. Conductor identification is done by color, enabling easy assignment during wiring operations.

Applications
This cable is universally suitable for use in dry and damp rooms and is especially appropriate for internal machine and plant-wide control circuits. It is resistant to many oils, plant and animal fats, and exhibits high chemical resistance. Due to its flexible structure, it is also suitable for areas with limited space where compact installation is required.

Functions and Features in Detail
The ÖLFLEX® HEAT 180 SiHF 2X0.75 features high heat resistance, withstanding temperatures up to +180 °C. This performance requires sufficient ventilation, as silicone cables may prematurely lose their mechanical properties above +100 °C in the absence of oxygen. The conductor insulation and outer sheath are made of a silicone compound that retains insulating properties even after being exposed to flame while stationary. The cable is halogen-free, meaning it does not release harmful halogen compounds during a fire.

Technical Explanation
The cable consists of two conductors, each with a cross-section of 0.75 mm², insulated with silicone. The outer sheath is also made of silicone compound, enhancing chemical and heat resistance. The silicone base allows for a flexible structure, making it easy to route in tight bending radii. The temperature resistance from -60 °C to +180 °C makes the cable suitable for applications in extreme environments, commonly found in industrial settings.

Compatibility and Accessories
The cable is designed for use in control and signal circuits and can be connected with standard terminals and connectors rated for 300/500 V. The halogen-free composition of the insulating and sheathing compound complies with DIN EN IEC 60754-1 requirements. The low corrosivity of gases during fire corresponds to DIN EN IEC 60754-2, enhancing fire safety. The cable is classified according to EU Directive 305/2011 (BauPVO/CPR), with exact classification available via the LAPP website by article number.

Installation and Mounting
The cable is intended for fixed installation and can be moved occasionally, provided no tensile stress occurs. Its flexible structure facilitates routing in confined spaces and complex bends. During installation, ensure adequate ventilation, especially when operating temperatures exceed +100 °C, to maintain the lifespan of the silicone insulation.

Operational Advantages
The ÖLFLEX® HEAT 180 SiHF 2X0.75 offers high thermal and chemical resistance, making it suitable for demanding industrial applications. Its halogen-free composition reduces fire hazard and the formation of toxic gases. The flexible structure enables easy installation, even in complex machine constructions. The cable is suitable for use in dry and damp rooms, increasing its versatility. Color-coded conductor identification simplifies wiring and maintenance.
