摘要

Many utilities still have paper-insulated pipe type cables innservice. In the near future they may have to replace some of thesensystems due to local increases in electric power demand or aged cableninsulation. In many cases the steel pipes are well protected againstncorrosion and thus suitable for further use. For retrofitting in suchninstallations, XLPE-insulated cables offer several advantages. Feltenn& Guilleaume Energietechnik AG has developed a new three-corenXLPE-insulated 64/110 kV cable with reduced insulation thickness (10nmm), that can be pulled into a pipe. In co-operation with VEW ENERGIEnAG, the cable performance is being investigated in a field test, thatnstarted in October 1996. This long-term loading cycle test will last fornthree years. The test voltage, applied between conductor and earth,namounts to 127 kV. The temperature is measured with the help of annoptical-fiber measurement system. This device is computer controlled andnworks as a remote monitoring system
