Electrical or optical cable having a moisture (humidity) sensor

摘要

In order to be able to locate a moisture ingress point in the case of a plastic-sheathed electrical or optical cable, a sensor element is arranged under the cable sheath (5), which sensor element has a core (23) (which transmits information) and a sheath (24) (which surrounds the core and makes it possible to transmit information), the sheath consisting of a material which dissolves in the presence of moisture. The sensor element may be either an electrical or an optical transmission element. <IMAGE>
