IEC 60370-2017 浸漬用絕緣樹(shù)脂和清漆耐熱性試驗規程--電擊穿法 Test procedure for thermal endurance of insulating resins and varnishes for impregnation purposes – Electric breakdown methods

This International Standard covers methods of test for the determination of thermal endurance (temperature index) of electrical insulating resins and varnishes for impregnation purposes.
It is done by means of impregnating glass cloth and measuring electric strength or breakdown voltage before and after heat ageing.
It covers the materials described in IEC 60455-3-5 and IEC 60464-3-2 and similar materials.dition 2.0 2017-12 INTERNATIONAL STANDARD NORME INTERNATIONALE colour inside Test procedure for thermal endurance of insulating resins and varnishes for impregnation purposes – Electric breakdown methods Méthode d’essai pour l’évaluation de l’endurance thermique des résines et vernis isolants d’imprégnation – Méthodes de claquage électrique IEC 60370:2017-12(en-fr) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 標準截圖
