US Patent 12111337 Constructive system regarding a capacitive sensor

A capacitive voltage sensor assembly includes a first electrode extending along a longitudinal axis, a tubular section surrounding a portion of the first electrode and positioned radially outward from the longitudinal axis and the first electrode, the tubular section including an insulating layer, an inner conductive layer, and an outer conductive layer, and a mass of dielectric insulating material at least partially enclosing the first electrode and the tubular section. The mass of dielectric insulating material fills through openings formed in the tubular section.
