Heating cables are designed to maintain fluids inside pipes and tanks at a predetermined temperature, which can be either an antifreeze level or a specific temperature required for industrial processes.
How Heating Cables Work
As the name suggests, heating cables are electrical cables designed to emit heat consistently or based on atmospheric conditions, ensuring the desired temperature set during the design phase is maintained.
Based on their operating principle, heating cables can be divided into two main categories: constant wattage heating cables and self-regulating heating cables.
Constant Wattage Heating Cables
Constant wattage heating cables with resistance wire typically consist of two power conductors embedded in an initial insulation layer. These are wrapped around the heating conductor, which is surrounded by a second insulation layer.
A protective braid and outer sheath ensure maximum safety.
Self-Regulating Heating Cables
Self-regulating technology ensures easy and safe operation over time.
The power output changes depending on the temperature the heating cable is exposed to, preventing overheating and unnecessary energy waste.
When the temperature drops, the self-regulating polymer contracts, allowing more current to flow and increasing the cable’s heat output. As the cable heats up, the polymer expands, reducing the current flow and consequently lowering the power output.
An additional advantage of self-regulating cables is their flexibility during installation.
These cables can be cut and spliced on-site, just like standard electrical cables.
Versatile Applications
Heating cables can be used in various contexts, including:
- External pipelines: To prevent water from freezing.
- Roofs, gutters, and downspouts: To avoid ice buildup that could block water drainage.
- Outdoor surfaces: Such as ramps and sidewalks, preventing ice formation and reducing the risk of slipping.
- Other applications: Valves, faucets, water meters, tanks, and animal drinking troughs.
A Real-World Case
By using Fantini Cosmi’s heating cables, the runway at Venegono Inferiore Airport was secured, preventing freezing and snow accumulation during winter.
For this case, the chosen solution was the K17C102 constant wattage heating cable for road ramps, providing 17W/m.
Easy Installation and Maintenance
Heating cables are relatively easy to install and require minimal maintenance. They can be cut and adjusted on-site, making them highly versatile for various applications. Additionally, self-regulating models automatically activate when the temperature drops below a certain threshold, optimizing energy consumption.
Fantini Cosmi offers a complete range of heating cables for any need.
