The ÖLFLEX® HEAT 180 SiHF 4G0.75 cable from Lapp is a heat-resistant silicone cable designed for use in plants and machines where high temperatures and chemical stress occur. The cable features a flexible construction and is suitable for fixed installation as well as occasional movements without tensile stress. It is universally suitable for wiring internal machine and cross-plant control circuits, particularly in areas where high thermal load capacity is required. Conductor identification is done by color, enabling easy assignment of individual conductors.

Applications

The cable is intended for use in dry and damp rooms and is insensitive to many oils, plant and animal fats. It exhibits high chemical resistance, making it particularly suitable for industrial applications in manufacturing, processing industries, or mechanical engineering. The operating temperature range extends from -60 °C to +180 °C, with the maximum temperature of +180 °C achievable under the condition of sufficient ventilation. Silicone cables lose their mechanical properties prematurely above +100 °C in the absence of oxygen; therefore, adequate air circulation in the operating environment is important.

Functions and Equipment in Detail

The cable consists of a halogen-free insulation and sheath compound classified according to DIN EN IEC 60754-1. This ensures low formation of toxic gases in case of fire. The insulating properties after flaming in a stationary state are ensured by the silicone compound of the conductor insulation and the outer sheath. The low corrosivity of the gases during fire corresponds to the standard DIN EN IEC 60754-2, increasing safety in case of fire. The cable is designed for an operating voltage of U0/U: 300/500 V and features a 4-conductor cross-section of 0.75 mm².

Technology Explained Simply

The use of silicone as insulation and sheath material enables high heat resistance up to +180 °C. Silicone is a synthetic polymer that remains stable at high temperatures and is simultaneously flexible. The cable is constructed flexibly, making it usable even in limited space conditions. The halogen-free composition of the insulation reduces the formation of toxic smoke gases in case of fire, improving safety in the operating environment. Conductor identification by color simplifies installation and maintenance.

Compatibility and Accessories

The cable is universally applicable and can be used in various industrial applications, particularly in control and regulation circuits. It is suitable for use in dry and damp rooms and can be used in plants that come into contact with oils, fats, or chemical substances. The cable is not specifically designed for outdoor use; however, it can be used in enclosed rooms with high thermal load. Compatibility with standard cable lugs and connectors is provided, as the cable is wired in a standard manner.

Installation and Mounting

Installation is done by fixed routing, with the cable not subjected to tensile stress. The cable is also suitable for occasional movements, provided no tensile load occurs. Installation requires sufficient ventilation to ensure the thermal stability of the silicone. The cable is flexible, which facilitates routing in confined spaces or complex paths. Conductor identification by color supports correct assignment during wiring.

Advantages in Operation

The high heat resistance up to +180 °C enables use in thermally stressed environments without the cable losing its electrical or mechanical properties. Chemical resistance against oils and fats reduces the risk of material damage. The halogen-free composition and low corrosivity of fire gases increase safety in case of fire. The flexible construction facilitates installation and maintenance, especially in complex plants. The cable is designed for an operating voltage of 300/500 V, making it suitable for many industrial applications.

Protection Rating and Fire Behavior

Fire behavior is classified according to EU Directive 305/2011 (BauPVO/CPR), with the exact classification available on the LAPP website by article number. The halogen-free compound and low corrosivity of fire gases contribute to safety.
