Electric anti-icing heating cable Hornisse 6,5mm (21m)

Product detailed description

Anti-icing heating cables are essential components in snow and ice management systems for commercial and residential properties. Installers typically work with these cables on access roads, footpaths, staircases and drainage systems to prevent ice formation and reduce slip hazards. The Hornisse 6.5mm cable is designed for integration into both new construction and retrofit projects where reliable de-icing is required in cold climates. It is commonly used in areas with heavy snowfall or frequent freezing conditions, particularly in regions where manual snow removal is impractical or unsafe. The cable's self-regulating properties ensure it adapts to ambient conditions, maintaining a maximum surface temperature of 10°C to prevent ice formation without overheating.

Installation requires careful planning to ensure even heat distribution and proper electrical connections. The cable must be laid in a continuous pattern across the surface or within gutters, avoiding sharp bends or overlapping sections. It is typically combined with a thermostat and moisture sensor to enable automatic operation, reducing energy consumption and extending system lifespan. The cable is compatible with standard electrical systems and requires a dedicated circuit with appropriate protection devices. Installers must verify that the surface temperature remains within safe limits and that the cable is not exposed to mechanical damage during or after installation.

Technical parameters

The 30 W/m power output ensures sufficient heat generation to melt snow and ice on medium to large surfaces. The 21m length is suitable for areas requiring extended coverage, such as long driveways or multi-level footpaths. The 3m connection cable allows for flexible positioning of the power supply unit. The maximum surface temperature of 10°C prevents overheating and ensures energy efficiency. These parameters are critical for determining the number of cables required for a given area and for selecting appropriate control components such as thermostats and sensors.

Installation and connection

Installation begins with a site survey to determine the layout and required cable length. The cable is laid in a zig-zag or parallel pattern across the surface or embedded in gutters, ensuring even heat distribution. A minimum ambient temperature of 5°C is required for installation to prevent premature activation. The 3m lead cable is connected to a power supply unit using standard electrical connectors. Installers must ensure that the cable is not overlapped and that it is secured with clips or fasteners to prevent movement. Common mistakes include incorrect spacing between cable runs, failure to install a thermostat, and neglecting to check the surface for moisture before activation. After installation, the system should be tested to confirm that the cable activates correctly and that the surface temperature remains within the specified range.

Compatibility and accessories

This cable is designed for use with thermostats and moisture sensors to enable automatic operation. The NTC-10 sensor is recommended for enhanced safety and efficiency. It is compatible with standard electrical systems and requires a dedicated circuit with appropriate protection devices. Related products include the 10m, 32m, 49m and 70m versions of the same model, which are suitable for different surface sizes. Installers should also consider the power requirements of the system and ensure that the electrical infrastructure can support the total load. Additional components such as junction boxes and mounting clips may be required depending on the installation location and surface type.

Technical background for designers

The Hornisse 6.5mm cable operates on a self-regulating principle, adjusting its heat output based on ambient temperature and surface conditions. The cable consists of two conductors with a polymer-based heating element that increases resistance as temperature rises, reducing power consumption. The outer insulation is made of UV-resistant PVC, providing protection against weathering and mechanical damage. The cable is designed for integration into both new and existing systems, with the option to control it manually or automatically. The system's efficiency is influenced by factors such as surface material, insulation, and the presence of snow or water. Designers should consider these variables when calculating the required cable length and power output for a given application.

Service and operation

Regular inspection is recommended to ensure the system remains functional and safe. Installers should check for signs of wear, such as cracks in the insulation or loose connections, and verify that the thermostat and sensors are operating correctly. The system should be tested periodically to confirm that the cable activates in response to freezing conditions. No scheduled maintenance is required beyond these checks, and the cable is designed for long-term reliability. If the system fails to activate or produces inconsistent results, the control components should be inspected for faults. The cable's self-regulating properties reduce the need for frequent adjustments, making it a low-maintenance solution for anti-icing applications.

Frequently asked questions

Can the Hornisse 6.5mm cable be used in gutters?
Yes, the cable is suitable for installation in gutters and downpipes to prevent ice formation and blockages. It should be embedded in the gutter material or secured with clips to ensure even heat distribution.

Is a thermostat required for automatic operation?
Yes, the cable is designed to work with a thermostat and moisture sensor for automatic activation. The NTC-10 sensor is recommended for enhanced safety and efficiency.

Can multiple cables be connected in parallel?
Yes, multiple cables can be connected in parallel to cover larger areas. The total power output should be calculated based on the surface size and required heat output.

What is the maximum surface temperature of the cable?
The cable is designed to maintain a maximum surface temperature of 10°C to prevent overheating and ensure energy efficiency. This temperature is sufficient to melt snow and ice without damaging the surface.
