The ÖLFLEX® HEAT 180 SiHF 7G4 connection cable from Lapp is a heat-resistant silicone cable designed for industrial applications involving high temperatures and chemical exposure. It is intended for fixed installation as well as occasional movements without tensile stress, and is suitable for wiring internal machine and cross-plant control circuits. The cable features high flexibility, making it particularly suitable for use in confined spaces. Conductor identification is done by numbers, enabling clear and unambiguous assignment of individual conductors.

Applications
This cable is universally applicable in dry and damp environments and is resistant to many oils, plant and animal fats. It exhibits high chemical resistance, making it suitable for applications in the processing industry, food technology, or chemical industry. 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 begin to lose their mechanical properties prematurely above +100 °C in the absence of oxygen, which is why adequate air circulation is required.

Functions and Features in Detail
The cable consists of a halogen-free insulation and sheath compound classified according to DIN EN IEC 60754-1. This ensures minimal generation of toxic gases in the event of fire. The insulating properties after flame exposure in a stationary state are ensured by the silicone compound used for conductor insulation and outer sheath. The low corrosivity of gases during fire, in accordance with DIN EN IEC 60754-2, enhances safety in case of fire.

Technical Explanation
The designation 7G4 indicates the number of conductors (7) and the cross-section (4 mm²) per conductor. The rated voltage is U0/U: 300/500 V, making the cable suitable for a wide range of electrical installations. The silicone insulation provides high heat resistance and flexibility, ensuring stability even under frequent bending stress. The flexible construction allows for easy installation, even in complex machine structures.

Compatibility and Accessories
The cable is designed for use in control and drive systems and can be connected with standard cable lugs, connectors, and other connection elements suitable for the rated voltage and conductor cross-section. Compatibility with other products in the ÖLFLEX® series is guaranteed, with specific accessory selection available on the LAPP website using the article number.

Installation and Mounting
Installation is performed by fixed routing, ensuring the cable is not subjected to tensile stress. For occasional movements, it must be ensured that no mechanical loads occur. The cable is installed in dry and damp environments, with ambient temperature remaining within the specified range of -60 °C to +180 °C. Sufficient ventilation is required to ensure effective heat dissipation.

Operational Advantages
The cable offers high chemical and heat resistance, extending its service life in demanding environments. The halogen-free compound reduces fire hazard and toxicity in case of fire. The flexible structure facilitates installation and placement in confined spaces. Its universal applicability in control and drive systems makes it a reliable solution for industrial applications.

Protection Rating
Chemical resistance and heat resistance are the key properties ensuring suitability for demanding environments.

Classified Fire Behaviour
According to EU Directive 305/2011 (BauPVO/CPR), the fire behaviour of the cable is classified. The exact classification can be determined via the LAPP website using the article number. The halogen-free compound and low corrosivity of gases during fire contribute to enhanced safety.

Conductor Identification
Conductor identification is done by numbers, enabling clear and unambiguous assignment of individual conductors. This is particularly important in complex wiring to avoid incorrect connections.
