Abstract (en)
[origin: WO2017182577A1] HVDCT air-core inductor (1) comprising: - at least one concentric winding layer (2-4, 4'), at the ends of which electric terminals (11, 12) are formed; and - an electrostatic shield (17) that includes: ∙ a layer of electrostatically dissipative material having a surface resistance ranging from 109 to 1014 ohm/square, ∙ at least one end of said layer (22) being provided with a collector electrode (19, 20) which extends essentially along the circumference of the end of the layer and is to be connected to one of the terminals (11, 12), the layer (22) being designed as a spray coating on an outer surface (21) of an exterior winding layer (4').
