摘要

通信線路系統材料，包含：金屬材料、合金材料、電子接點、高分子材料及水泥建物等。連接電話中心局間與用戶間之構成稱之為線路，線路一般由地上的線材設備與地下管道設備組合而成，前者包括：明線、電桿、自持線及光電纜等設備；後者則包括：管道、人手孔及洞道等設備。線路金屬材料與環境之交互作用產生不同型態之腐蝕。本研究利用大氣腐蝕暴露試驗、陰極防蝕法及交流阻抗測試等方法探討通信線路系統材料之腐蝕特性及其防治方法。

The telecommunication systems outside plant are made of a variety of materials: metals, alloys, electrical contacts, polymers, concrete structure and so on. The wires which connect telephone offices to subscribers and to other telephone offices and the objects which support them are called outside plant. The outside plant is composed of line plant and underground plant. The former includes open wires, telephone poles, self-supporting wire, cables and optical fiber. The latter includes ducts, manholes, hand-holes and cable tunnels. The interaction between the outside plant metal components and the environment leads to various types of corrosion. Measurements of atmospheric exposure test, cathodic protection and ac impedance technique have been conducted to evaluate the corrosion behaviors and its prevention control of telecommunication systems.
