AN ANALOGUE LINE TYPE WIRE CABLE OF TEMPERATURE SENSING FOR DETECTING FIRE

摘要

An analogue line type wire cable of temperature sensing for detecting fire comprises two detecting conductors (5,9) disposed in parallel, and a NTC characteristic intercluding layer (7) and a meltable insulating layer (6) arranged between two detecting conductors (5,9) which are disposed in parallel, and a conducting layer (8) which is connected discontinuously and disposed along the length direction of the wire cable for fire detecting between the NTC characteristic intercluding layer (7) and the meltable insulating layer (6). At least one detecting conductor of two detecting conductors is an elastic conductor.
