Oil immersed top core current transformers

For very high voltage, over 300KV, the AOK type current transformer of the top core, or inverted type wil be more cost effective. In the AOK, the cores are located in a strong aluminium housing, which is supported by a steel tube. The insulation is mostly machine wound to ensure a high and uniform quality. The oil expansion is contained by a bellow system, made of aging synthetic rubber.
