ABSTRACT:
A metallized dielectric film (103, 104, 105, 106) is used for manufacturing electrical power capacitors of self-healing type. The metallization (60, 60', 601, 601'), which is obtained by known deposition techniques for zinc, aluminum or zinc-aluminum alloys, has a variable thickness of substantially decreasing profile, such that the resistance, evaluated in ohms/square .OMEGA./.quadrature.), varies from a minimum of 1 .OMEGA./.quadrature. in the contact region (51, 51', 501), to a maximum of 60 .OMEGA./.quadrature. (on the opposite side). The thickness of the metallization (60, 60', 601, 601') is reduced by a continuous variation of for example inverse square type.
