The connection cable ÖLFLEX HEAT 180 SiHF 6G0,75 from Lapp is a heat-resistant silicone cable designed for use in industrial applications with high thermal loads. It features a flexible construction and is suitable for fixed installation as well as occasional movements without tensile stress. The cable is universally used for wiring internal machine and plant control circuits, particularly in environments where high temperatures, chemical influences, or humidity occur.

Applications

The cable is suitable for use in dry and damp rooms and is characterised by high resistance to many oils, plant and animal fats. It is chemically resistant in many respects and is therefore suitable for applications in the packaging industry, food processing, chemical industry, and in machine and plant engineering. The flexible design allows use in limited space, for example in compact control units or tight machine components.

Functions and Equipment in Detail

The cable features conductor identification by numbers, which simplifies assignment and wiring. The individual conductors are insulated with a silicone compound, which is also used in the outer sheath. This material selection ensures high insulation performance even after flaming in a stationary state. The cable is halogen-free according to DIN EN IEC 60754-1, which improves fire behaviour and reduces the formation of toxic gases in the event of fire. Additionally, it exhibits low corrosivity of gases during fire, according to DIN EN IEC 60754-2.

Technology Explained Simply

The cable is designed for operating voltages of U0/U: 300/500 V and can withstand 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 flexible structure of the cable enables easy installation and mounting, even in tight bending radii. The silicone compound ensures high chemical resistance and long service life under high thermal loads.

Compatibility and Accessories

The cable is universally applicable and can be connected with standard terminals, plug connectors, and other connection elements suitable for silicone cables. Its use in control and signal systems is particularly suitable due to its electrical and thermal properties. The cable is classified according to EU Directive 305/2011 (BauPVO/CPR), with exact article number selection available on the LAPP website.

Installation and Mounting

The cable is intended for fixed installation and can be used for occasional movements without tensile stress. The flexible structure facilitates mounting, especially in complex systems or limited space. Installation is typically carried out without special tools, with the cable’s flexibility and bend strength supporting the process.

Operational Advantages

The high heat resistance up to +180 °C enables use in thermally demanding environments without impairing the cable’s electrical or mechanical properties. Chemical resistance to oils and fats reduces the risk of insulation failure. The halogen-free composition and low corrosivity of fire gases increase safety in the event of fire. The flexible design and easy wiring through numbered conductors improve installation efficiency and system maintainability.
