Electric anti-icing heating cable Hornisse 6,5mm (49m)

Product detailed description

Electric anti-icing cables are essential components in winter maintenance systems, particularly in areas prone to heavy snowfall and freezing conditions. Installers commonly apply these cables to surfaces such as access roads, footpaths, steps and roof guttering to prevent hazardous ice accumulation. They integrate seamlessly into automated control systems using thermostats and moisture sensors, ensuring energy-efficient operation while maintaining safety standards. The flexible design allows for straightforward installation on flat surfaces or within complex structures, making them suitable for both residential and commercial applications.

The Hornisse 6.5mm heating cable is specifically suited for environments requiring continuous protection against ice and frost. Its self-regulating nature means it adjusts its output based on ambient conditions, preventing overheating and unnecessary energy consumption. This makes it ideal for long-term deployment in cold climates where surface integrity and slip prevention are critical.

Technical parameters

Installation and connection

Correct installation involves securing the cable along the desired surface or within gutter channels using clips or mounting brackets. The twin-core, round construction allows for easy handling and placement in tight or curved spaces. The connection cable should be routed to a suitable junction box, ensuring all electrical connections are made in accordance with local regulations and manufacturer guidelines. A minimum ambient temperature of 5 °C should be maintained during installation to avoid stress on the insulation.

Installers should verify that the cable runs are free from sharp bends or kinks which could compromise performance. The cable must be spaced evenly to ensure uniform heat distribution, especially when covering large or irregular surfaces. Common errors include incorrect spacing, over-bending, or failing to secure the cable properly, which can lead to poor thermal efficiency or mechanical failure over time.

Compatibility and accessories

This anti-icing cable is designed for use with standard 230 V electrical systems and requires compatible control units for automated operation. For enhanced safety, the NTC-10 temperature sensor is recommended to monitor and regulate system performance. Related models include the Hornisse 6.5mm (10m), Hornisse 6.5mm (21m), Hornisse 6.5mm (32m), and Hornisse 6.5mm (70m), which offer similar specifications in different lengths to suit various project scales.

Technical background for designers

The Hornisse cable employs a self-regulating heating element that adjusts its output in response to changes in ambient temperature. This ensures that the cable does not exceed a maximum surface temperature of 10 °C, protecting both the cable itself and the surrounding materials from thermal damage. The outer jacket is made of UV-resistant PVC, offering durability under prolonged exposure to sunlight and weather elements. The twin-core design provides balanced power delivery and improved mechanical strength, supporting long-term reliability in outdoor environments.

When integrating the cable into a larger system, designers must account for the overall power demand and ensure that the electrical infrastructure can support the load. Factors such as surface area, climate severity and the presence of snow retention features influence the required cable density and layout. Proper insulation and sealing of connections are also critical for maintaining system integrity and preventing water ingress.

Service and operation

Regular inspection of the cable’s physical condition and electrical connections is recommended to identify potential issues early. Any signs of damage, such as cuts or abrasions in the insulation, should be addressed immediately to prevent system failure. The control unit and associated sensors should also be checked for proper function, ensuring accurate temperature regulation and response to environmental changes.

During routine maintenance, the cable should be visually inspected for wear and tear, particularly at points where it passes through structural gaps or bends. While no specific service intervals are provided in the technical documentation, monitoring the system’s performance during peak usage periods helps ensure continued effectiveness and safety.

Frequently asked questions

Can the Hornisse cable be used in combination with a thermostat?
Yes, the cable functions optimally when integrated with a thermostat and moisture sensor, enabling automatic activation based on temperature and humidity levels.

Is it necessary to install the NTC-10 sensor?
While not mandatory, the NTC-10 sensor enhances system safety by providing real-time temperature feedback and preventing overheating.

What happens if the cable is exposed to temperatures below 5 °C during installation?
Low temperatures during installation can affect the cable’s insulation integrity. It is important to follow the recommended minimum ambient temperature to avoid performance issues.

How is the cable secured during installation?
The cable should be fixed in place using appropriate clips or fasteners to prevent movement and ensure even heat distribution across the intended surface.
