    摘要: A liquid leakage detector line is provided with a coating layer having at least liquid-absorbent properties and disposed at the outer periphery of a core which contains a pair of wiry electrodes disposed nearly parallel with each other, wherein the wiry electrodes comprise conductors which are extrusion coated with a polyester elastomer as an insulator. The liquid leakage detector line has excellent mechanical strength, rubber elasticity, resistance to fatigue from flexing and crack propagation resistance, and is free from the occurrence of pinholes, crazings, etc. inside the insulator during production and laying due to external forces applied to the wiry electrodes, such as pressure, tensile force, bending, and the like. As a result, erroneous actuation due to rainfall, etc. does not occur, and the time required to detect the sulfuric acid or other liquid to be detected has little dependence on the temperature, and short detection times for leaking liquid are possible even at low temperatures.
