PROBLEM TO BE SOLVED: To provide low-cost fire detection means that can replace high-cost means for detecting a fire of a solar panel, such as an infrared camera or a detection sheet used attached on the entire solar panel.SOLUTION: A fire of a solar panel, for example, is detected using a fire detection line which includes: a core wire; an internal conductor spirally wound around the outside of the core wire; a fusible coating on the internal conductor, which melts by heat of a fire; an outer conductor spirally wound around the outside of the coating; and a heat-resisting sheath outside the outer conductor.SELECTED DRAWING: Figure 1 |
