摘要：
The effects of wet service conditions and accelerated aging of cables on the density of insulations and their electrical characteristics (breakdown voltage -AC BDV) have been studied. The accelerated aging of crosslinked polyethylene cable insulations: steam and dry cured with water tree retardant crosslinked. polyethylene (TR-XLPE) and without water tree retardant crosslinked polyethylene (XLPE was performed at elevated temperatures and high pressure of oxygen. During tests, the tap water was injected (1) into the cable conductor with cable ends closed. The cross-linked polyethylene cable insulations together with the water present in the cable were subjected to electrical stress and heating. The results of water absorption, and electrical characteristics are discussed.
