WebThe mixtures containing fillers were thoroughly mixed in a Molteni type vacuum mixer, evacuated, then poured into a casting mold and cured at 100 °C. Test samples were cut from the sheets and the inclined plane electrical erosion test (LEC 587) was performed on them. The results are summarized in Table 4.b. 5 parallel samples were investigated. WebInsulators after 20 years in service in heavily polluted environments were investigated regarding damages caused by tracking and erosion. In order to compare the field results to those of available material tests, the "inclined plane test" (IEC 60587) and the "low current arc resistance test" (IEC 61621) on slab shaped test samples were performed.
