臺北捷運軌道工程導電軌系統材料選用與測試

魏道佳¹ 顏啟仁²

摘要

提供電聯車動力來源的供電方式採用位於運行軌旁之導電軌集電系統，具有安裝便捷、
維修便利及不對周遭景觀造成衝擊之優點，臺北捷運高運量軌道採用的型式為最具安全性的
「下觸式」導電軌。本文乃以臺北捷運系統導電軌為例，說明材料選用、供料規範與測試驗
證等。

Abstract

The power for driving electrical multiple unit (EMU) trains is provided by a conductor
rail system installed alongside the running rail. The conductor rail system is characterized by
the following advantages: easy fixing, painless maintenance, and non-negative impact on its
surroundings. The conductor rail adopted by Taipei MRT is the safest "bottom contact" type. This

article describes the principles of material selection, material specification, and material testing and
verification using the Taipei MRT conductor rail system as an exemple.

Keywords: molecular fusion, co-extrusion, welding process, ramp assembly, expansion joint,
insulated bracket.
