As the most broad and comprehensive sector – and the most commonly associated application of linear heat detection (LHD) – Thermocable has expansive knowledge of use within this field. Frequently referred to as ‘facilities and systems that serve a country, city, or geography’, the infrastructure market is essential for every economy, sustaining and enhancing ‘societal living conditions’.
With such widespread facets of infrastructure contributing to worldwide ecosystems – including highways, transport, sewers, telecommunications and electrical networks, early detection is fundamental to protecting these fixed assets from the devastating impact of fire.
And that is exactly what LHD is for.
Often referred to as line type heat detection, LHD is a cable-based type of early fire detection, designed to generate either an alarm, or automatically activate a fire suppression system.
The cable itself acts as a heat detector, so when a physical or electronic change occurs, this is identified anywhere along the cable’s entire length (reaching up to 3km). Once the temperature around the cable reaches a certain threshold, the cable can trigger an alarm and subsequently a suppression system.
In a nutshell, this technology provides a much needed early warning detection of fire and/or overheating.
With Thermocable’s ProReact range activating at temperatures of 68, 78 and 88 degrees Celsius, it’s the perfect solution for detecting an overheat situation before a fire starts, enabling prevention or rapid suppression.
With LHD digital technology being able to detect alarm location at any point along the cable’s length, key applications include:
