Inclined plane test composite insulator
WebDec 12, 2024 · In this era, silicone rubber (SiR) is very known polymeric composite insulator, which is mainly composed of base polymer, fillers and additives. SiR is characterized by high thermal stability, stable performance under a wide temperature range and excellent resistance to corona, ozone and weathering. 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.
