摘要

本論文研究之縮小161kV級交連PE地下電纜完成外徑，由於交連PE電纜具有比充油電纜較優越的電氣特性、裝置快速和維護容易等因素，所以在台灣被廣泛地使用於161kV的地下傳輸線。目前台灣地區之輸電線路，可分為架空線路及地下電纜兩種，其中地下電纜係用於人口密集的都會區，由於空間狹隘，土地取得困難，且為兼顧都市景觀，故皆在道路下面埋設管路或箱涵再將電纜線裝置其中，因此所使用之地下電纜的外徑，若能在不影響用電安全及品質的要求下，得以縮小完成外徑，將可節省所佔用的管路面積及施工簡單化。本論文係以絕緣材料電氣強度之觀點，使用交流耐電壓試驗和衝擊波耐電壓試驗來討論縮小161kV級交連PE地下電纜完成外徑的可行性。

A procedure is studied for reducing outer diameter of 161kV XLPE. In Taiwan, XLPE (cross-linked polyethylene) cables are being used more widely as 161kV underground transmission lines owing to the superior electrical characteristics, quick installation and easy maintenance when compared to OF (oil-filled) cables.
The transmission lines are divided into two categories, one is overhead lines, the other is underground lines. The underground transmission lines are laid out cater for metropolis of high density population because urban space is occupied by lots of building and land is hard to access by government. Furthermore, it also improves city landscape. Therefore, it is better to lay out cable into duct or tunnel buried under road. If we can reduce outer diameter of underground cable within utility safety and quality margin, it will shrink the cross area of duct pipe and simplify the erection of underground cable system. In this paper, we discuss the feasibility of reducing outer diameter of 161kV XLPE underground cables through the AC voltage breakdown test and impulse voltage breakdown test with respect to the electrical strength of insulating material.
