Electric anti-icing heating cable Hornisse 6,5mm (70m)
Code: HOCAB-ODR-30-2100Product detailed description
Electric anti-icing cables are essential components in snow and ice management systems for residential and commercial properties. Installers typically apply these cables to external areas such as driveways, footpaths, steps, and drainage systems including gutters and downpipes. The Hornisse 6,5 mm cable is designed for environments exposed to freezing conditions, ensuring continuous operation without manual intervention. It is particularly useful in regions with heavy snowfall and frequent icing, where slip hazards and structural damage from ice accumulation are concerns. The cable operates automatically in conjunction with thermostats and moisture sensors, activating only when necessary to maintain energy efficiency.
The installation process involves securing the cable along the designated surface or within a channel, ensuring even coverage and proper spacing. For gutters and downpipes, the cable is routed through the system to prevent blockages caused by ice. The self-regulating nature of the cable ensures that it adjusts its heat output based on ambient conditions, preventing overheating and reducing the risk of damage to the surface or surrounding structures. The minimum installation temperature is 5°C, so planning must account for seasonal conditions during fitting.

Installation and connection
The installation procedure begins with planning the layout to ensure even coverage and avoid overlapping sections. The cable should be laid in a straight or zigzag pattern, depending on the surface, with a minimum spacing of 5 cm between parallel runs. For gutters and downpipes, the cable is threaded through the system, avoiding sharp bends to prevent damage. The cable must be fixed securely using clips or mounting brackets to prevent movement during operation.
The connecting cable is terminated at the control panel, which should be located in a dry, accessible location. The 230 V supply is connected via a dedicated circuit with appropriate fuse protection. Before energising the system, the continuity and insulation resistance of the cable should be tested to ensure there are no faults. Common installation errors include incorrect spacing, poor securing of the cable, and failure to integrate a thermostat or NTC sensor, which can lead to inefficient operation or overheating.
Compatibility and accessories
This Hornisse cable is designed to work with standard thermostats and NTC-10 temperature sensors for automatic control. A thermostat ensures the system activates only when temperatures fall below a set point, while the NTC sensor provides additional safety by monitoring surface conditions. Additional accessories such as junction boxes and cable glands may be required depending on the installation site.
Related products include the Hornisse 6,5 mm anti-icing cables in lengths of 10 m, 21 m, 32 m and 49 m. These can be used in combination to cover larger areas or to extend existing systems. When planning a multi-cable installation, ensure all components are from the same range for compatibility and uniform performance.
Technical background for designers
The Hornisse cable operates on a self-regulating principle, meaning its resistance varies with temperature to limit heat output. As ambient temperature drops, the cable increases its power output until it reaches a maximum surface temperature of 10°C, after which it stabilises. This prevents excessive heating and reduces the risk of thermal stress on the surface or surrounding materials.
Constructed with a round, twin-core design and 100% shielding, the cable is protected by a UV-resistant PVC outer insulation, making it suitable for long-term outdoor use. The materials are selected to resist mechanical damage and environmental exposure, ensuring durability under repeated freeze-thaw cycles. Integration into a larger system requires careful consideration of control logic and sensor placement to optimise efficiency and safety. The service life of the cable is influenced by installation quality, environmental conditions and the presence of protective sensors.
Service and operation
Regular visual inspections are recommended to check for signs of wear, damage or displacement of the cable. Any exposed or cut sections should be repaired immediately to prevent electrical faults. The control system should also be checked periodically to ensure sensors and thermostats are functioning correctly. No scheduled service intervals are specified, but prompt attention to any faults is essential to maintain system integrity.
Frequently asked questions
Can the Hornisse cable be used in both horizontal and vertical applications?
Yes, the cable is suitable for both flat surfaces and vertical installations such as gutters and downpipes. For vertical use, ensure the cable is securely fastened to prevent sagging or movement.
Is it necessary to install an NTC sensor with this cable?
While not mandatory, it is recommended to install an NTC-10 sensor for enhanced safety and efficiency. The sensor helps monitor surface conditions and prevents unnecessary operation during mild weather.
Can multiple Hornisse cables be connected in parallel?
Multiple cables can be connected in parallel, provided the total load does not exceed the capacity of the power supply and control system. Ensure all connections are made according to the manufacturer’s guidelines.
What is the maximum temperature the cable can reach?
The cable is designed to self-regulate and will not exceed a surface temperature of 10°C, regardless of ambient conditions. This feature prevents overheating and ensures safe operation on sensitive surfaces.
