Title: Flexible electric cable having monitoring elements
Inventor: PUFF ERICH DIPL ING
IPC: H01B7/04
Filed: 1989-03-21
Abstract: In order to be able to monitor the effect of unacceptably high compression stresses on a multicore flexible electric cable (20), at least two conductive elements (27, 29) are provided which consist of metal wires and either surround in each case one of the live electrical wires or surround the cable cores (21, 25) jointly in a concentric arrangement. Arranged between two monitoring elements there is in each case one insulating layer (28) whose resistance to compression stress is less than the corresponding resistance of the insulation (23) of the live electrical wires. In the event of an unacceptably high compression stress, the insulating layer (28) splits and the monitoring elements (27, 29) come into contact with one another. Such a cable construction, in which the monitoring elements preferably consist of two braidings of copper wires arranged between the inner sheath (26) and the outer sheath (30), can be used especially for supplying electrical power to trench-digging machines.   <IMAGE>
