中文摘要 | 本文針對有白蟻蹤跡的PVC電纜之破損原因進行研究分析,內容項目包 括:(1)勘查變電所電纜溝環境和白蟻生態習性的關連性; (2)PVC電纜破孔之巨、微 觀分析,研判破孔的發生原因;(3)評估該電纜經二十二年使用後的材質劣化狀 況;(4)驅除白蟻的對策。研究結果顯示電纜溝中殘存的木模板和濕氣提供白蟻孳 生環境。電纜破孔邊緣呈被白蟻啃咬的凹凸鋸齒狀,白蟻分泌物質會侵蝕貫穿 PVC包覆層,而電纜內棉線包帶及麻紗提供白蟻生存的食物,由較完整的電纜取 樣分析,証明材質特性尚未嚴重劣化。建議白蟻驅除以電纜溝建築時環境的選擇 與整理最為重要。 |
英文摘要 | A case study on damage of PVC cable by termites is presented in thisarticle. It proceeds as follows: (1) Surveying the ecology of termites in thecable duct. (2) Investigating the damaged PVC cables with micro and macroanalysis methods. (3) Evaluating the material properties of PVC cable with22 years service. (4) Devising a method to get rid of the termites. Study result shows that (1) The residual of moldboard left in the cableducts and the humidity constitute a prosperous environment for termitesgrowing. (2) The mechanism of damaging is: through the termites-indentedcoat of PVC cable, the termites secretion erodes through the cable, theexposed wrapping textile fabrics and the yam Fillers become foods fortermites in turn. (3) Material performance test indicated that most of thecable is still serviceable except those section damaged by termites. (4) Thebest way of getting rid of termites is cleaning up of the cable duct. |
