Heavy current cable sleeve - has screening electrode with radial openings for oil flow, insulation with matching channels and outer insulator

摘要

The sleeve for heavy current paper or plastic insulated cables, impregnated with oil, has a screening electrode (3) with radial openings for the oil (1,2) around its periphery. These line up with the longitudinal channels (5,6) in the insulating covering layer (4,7) and at the mouth of the channels, an additional insulating body (10) is arranged. ADVANTAGE Simple inexpensive design with reduced oil flow resistance.
