Electrical equipment employing insulants.

摘要

A cable has a stranded conductor (1) having a central duct (2) filled with insulating oil under pressure. The conductor (1) is surrounded by an oil-pervious taped insulant (4) in turn surrounded by an insulant (6) in the form of particles of solid insulating material in the insulating fluid. The insulating fluid acts as a discharge supressant and is in the form of a thin film.
