摘要: Studies of the merry-go-round test (MGR), using a newly built apparatus, and influence procedure on performance different HV polymeric outdoor insulation housing materials are presented. In test, surface leakage currents, mass wettability changes studied samples were monitored. The investigated bisphenolic cycloaliphatic epoxies, HTV RTV silicone rubbers, EPDM rubbers. Results show that epoxies containing silane-treated filler perform very well in test. except for preservation their hydrophobic properties, was comparable to This is contradictory materials' field indicates there still problems with interpretation MGR results correlation actual service experience. >
