Abstract: In a process for the manufacture of self-regenerating capacitors, there is applied to insulating strips (3, 4) before they are rolled up, metallized layers (6, 7; 8, 9) of which the median thickness is decreased towards either side of the strips to leave a median zone of metallization (5) of normal thickness located at a specified distance from the edges of the insulating strips, and a thermal circuit-breaker (14, 19) is inserted on the axis of each coil in the vicinity of said zone of greater thickness, with the short-circuit device being coupled in series with a connection wire of each of the coils (10, 11).
