電氣絕緣（Electrical Insulation） 是指使用特定材料阻止電流在導體之間非預期流動的技術措施。其核心功能是在電氣設備或系統中建立高電阻屏障，确保電流僅在設計路徑中傳輸，從而防止短路、漏電、觸電風險并保障設備正常運行。
絕緣材料通過極高的電阻特性（通常超過10¹² Ω·m）阻礙電荷遷移。當施加電壓時，材料内部僅産生極微弱的洩漏電流（納安級），例如聚乙烯在1kV/mm場強下洩漏電流低于10⁻¹² A 。
在導體間形成介電屏障，支撐系統電壓。例如輸電線路絕緣子需耐受數百kV電壓而不擊穿 。
材料被擊穿前承受的最大電場強度，單位kV/mm。典型值：
表征材料阻隔直流電流的能力，标準測試需在500V DC下測量（依據IEC 60243）。
| 材料類型 | 應用場景 | 特性 |
|---|---|---|
| 聚合物 | 電線包覆（PVC/XLPE） | 柔韌性高，成本低，耐化學腐蝕 |
| 陶瓷 | 高壓絕緣子、火花塞 | 耐高溫（>1000°C），機械強度高 |
| 玻璃纖維 | 電路闆基材（FR-4） | 尺寸穩定，阻燃性優良 |
| 絕緣油 | 變壓器冷卻與絕緣 | 高擊穿電壓（>30kV），散熱性強 |
電氣絕緣性能需符合國際标準：

"Electrical insulation"（電絕緣）指阻止電流流動的材料或技術，其核心作用是隔離帶電導體，防止電流意外洩漏或短路，保障設備安全和人員安全。以下是詳細解釋：
電絕緣材料具有極高的電阻率（通常大于 (10 Omega cdot m)），能有效阻礙電荷遷移。其工作原理基于材料内部的原子結構——電子被緊密束縛，無法自由移動形成電流。例如，橡膠的電阻率約為 (10^{13} Omega cdot m)，遠高于銅（(1.68 times 10^{-8} Omega cdot m)）。
電絕緣失效可能導緻觸電、火災或設備損壞。例如，2023年某國電網事故分析顯示，23%的故障源于絕緣老化。因此，定期檢測（如耐壓測試、絕緣電阻測試）和材料升級（如納米複合絕緣材料）是行業重點。
如需進一步了解絕緣材料标準（如IEC 60243）或具體測試方法，可查閱電氣工程手冊或行業規範。
