ELECTRICAL CONDUCTOR FOR HIGH-CURRENT BUSHING INSULATOR Russian patent published in 2014 - IPC H01B17/26 

FIELD: electricity.

SUBSTANCE: electrical conductor (S) is intended to pass rated current in a high-current bushing insulator of a power plant transformer mounted in the current circuit between the generator and primary windings of the transformer at the generator circuit-breaker. The conductor has the main section (30) passing along the axis (A) and a shell with a cylindrical surface and two electrical leads (10, 20), at that the first lead (10) has two parallel contact surfaces (11, 11'). According to the invention the second lead (20) out of two electrical leads (10, 20) is coupled without connection to the main section (30) of the conductor and the first electrical lead (10) is made hollow and placed perpendicular to the axis (A), it has an oval shape with two longitudinal front faces, which form two contact surfaces (11, 11'). Between the first electrical lead (10) and the main section (30) of the conductor there is a hollow section (40) of the electrical conductor that connects the electrical lead (10) to the main section (30) of the conductor forming a smooth transition from two contact surfaces (11, 11') of the first electrical lead (10) to the shell surface of the conductor main section (30).

EFFECT: inventions allow reduction of power losses in the electrical conductor with maintenance of its compact design.
