瞬態過電壓是指在極短時間內發生的高電壓脈衝，可能持續幾微秒到幾毫秒。這些過電壓不屬於設備正常運作的工作電壓範圍，但必須被考慮進安全設計，因為它們足以擊穿絕緣或設備損壞。

不會。海拔高度只會影響空氣的介電強度，因此只會調整「間隙距離」；爬電距離設計不受高度影響。

因此，選擇適當的爬電距離對於減少電氣故障風險至關重要。所需距離取決於電壓水平、絕緣材料類型以及運行環境條件。通過確保組件符合爬電標準，設計人員可顯著提升電氣系統的安全性與可靠性，尤其在高壓應用中。
不行。兩者是獨立的安全設計參數，爬電距離用於防止表面漏電，間隙距離則防止空氣放電。缺一不可，需分別依標準查表計算。

梳狀圖案，梳狀電路是一種“多指”交錯密集電路圖案，可用於電路板清潔度和綠色油漆絕緣的高壓測試。
爬電距離的選擇以日常運行時的額定工作電壓為依據，工作電壓越高，對絕緣的需求越大，所需爬電距離也越長。
By streamlining the whole course of action—from purchasing and parts sourcing PCB絕緣 to PCBA prototyping—you may receive your concluded boards in as quick as one 7 days. Allowing you to definitely iterate, boost, and deliver punctually and even.
At that point, Microsoft Advertising and marketing will make use of your complete IP handle and consumer-agent string to make sure that it could possibly appropriately process the advert click on and charge the advertiser.
．介質不同：間隙距離依賴空氣的絕緣能力，而爬電距離取決於固體絕緣材料表面的性能。
