Please note that Pertronic-Anbesec LHD Cable is preferred for new installations.

Linear Heat Detection Cable (LHD) is designed for use where traditional point heat detectors are unsuitable.

The LHD is a fixed temperature sensor capable of initiating an alarm if its temperature threshold exceeded.

It consists of two tri-metallic conductors twisted together to keep them under mechanical tension. Each conductor is individually coated in a temperature-sensitive polymer that detects heat conditions anywhere along its length.

It is not required that a specific length be heated in order to initiate an alarm. Therefore, LHD provides the advantage of line coverage with point sensitivity.

LHD cable is available with a PVC or Nylon outer sheath.

Typical applications include tunnels, mining, manufacturing, warehousing, cold stores, communications and general instustry, etc.
