The connection cable ÖLFLEX HEAT 180 SiHF 16G1,5 from Lapp is a heat-resistant silicone cable designed for use in industrial plants and machinery. It is intended for wiring control circuits that operate under high temperatures and in chemically demanding environments. The cable features a flexible structure and is suitable for fixed installation as well as occasional movement without tensile stress. Conductor identification is done by numbers, enabling clear assignment of conductors during wiring operations.

Applications
The cable is universally applicable in dry and damp rooms, particularly in areas where high temperatures and chemical influences occur. It is resistant to many oils, plant and animal fats, and exhibits high chemical resistance. Applications range from internal machine wiring to plant-wide control circuits, where high reliability under extreme conditions is required.

Functions and Equipment in Detail
The cable is made of a silicone compound serving as both conductor insulation and outer sheath. This material selection ensures high insulation performance even after flame exposure in a stationary state. The halogen-free composition of the insulating and sheathing compound complies with DIN EN IEC 60754-1 and reduces the formation of toxic or corrosive gases in case of fire. The low corrosivity of the gases during fire is confirmed according to DIN EN IEC 60754-2.

Technology Explained Simply
The cable is designed for operating temperatures from -60 °C to +180 °C. The heat resistance up to +180 °C requires sufficient ventilation, as silicone cables may prematurely lose their mechanical properties above +100 °C in the absence of oxygen. The operating voltage is U0/U: 300/500 V, sufficient for a wide range of industrial applications. The flexible construction allows use in areas with limited space without compromising functionality.

Compatibility and Accessories
The cable is designed for use in systems requiring high thermal and chemical resistance. It is suitable for connections in machine building, packaging technology, plastic processing, and other industries where high temperatures and aggressive environments occur. The cable is not specifically combined with other products, but it can be used as a universal connection component in existing systems.

Installation and Mounting
The cable is intended for fixed installation and can be moved occasionally, provided no tensile stress occurs. The flexible structure facilitates routing in confined spaces and complex wiring situations. Installation must comply with applicable regulations for electrical installations, taking into account ventilation of the environment at high temperatures.

Operational Advantages
The heat-resistant cable offers high reliability under extreme conditions. The chemical resistance against oils and fats, as well as the halogen-free composition, enhance operational safety. The flexible structure and low corrosivity of gases during fire contribute to the safety and longevity of the installation. Thus, the cable is a robust solution for demanding industrial applications.
