| 摘 要： | The past decade has been very busy and exciting times for the underground power cable industry.This paper starts with a brief introduction of the past 100 years and then reviews papers presented at recent JICABLE and CIGRE conferences.Over the past decade both on-line and off-line diagnostics have seen rapid development,HVDC cables have extended interconnection lengths to 600 km and HVAC cables are now commonly installed for distances up to 100 km.And at the same time advanced materials,higher operating voltages and improved cable accessory designs have supported all of these advances.In short,it is an excellent time to review underground power cable technology.
