樹枝狀環氧應用于電器絕緣件

樹枝狀環氧樹脂應用于國家電網用電器絕緣件,酸酐固化的環氧體系,彎曲強度達到160MPa(常規環氧體系為140MPa),沖擊強度15.5KJ/m2(常規環氧體系10.5KJ/m2,進口產品體系13.3KJ/m2),抗彎強度19300N(常規環氧體系15200N),電性能如表:


測試項目測試標準測試結果
工頻干耐受典雅試驗42V/1min無擊穿閃絡現象
局部放電起始電壓>13.2KV符合技術要求
局部放電熄滅電壓>13.2KV符合技術要求
局部放電(13.2KV)≤3PC符合技術要求
抗彎試驗≥15000N19300N


樹枝狀環氧樹脂帶來的綜合性能是其他助劑無法達到的,超出進口產品。
