US Patent 11079410 Constructive system regarding a capacitive sensor

A construction system regarding a capacitive voltage sensor, comprises a source electrode (110/210/310/410), a tubular body (120/220/320/420), and a mass of dielectric insulating material (140/240/340/440). The tubular body (120/220/320/420) comprises: a self-supporting tubular laminar element (123/223/323/423) made of insulating material, in which the self-supporting tubular laminar element (123/223/323/423) is stretched to form the support structure for said tubular body (120/220/320/420); a first thin layer (124/224/324/424) of conductive material applied to the outer surface of said self-supporting tubular laminar element (123/223/323/423), wherein said first thin layer (124/224/324/424) of conductive material is intended to perform the function of an electric screen; a second thin layer (125/225/325/425) of conductive material applied to the inner surface of said self-supporting tubular laminar element (123/223/323/423), wherein said second thin layer (125/225/325/425) of conductive material is designed to form an armature for a capacitive coupling.
