Abstract

A bus system for use in electrical distribution equipment includes a generally U-shaped arrangement of conductor conductors for supplying very high amperage (e.g., above 2000 amps) alternating current to the electrical distribution system. Compared to prior-art conductor arrangements, using the present arrangement, the conductor conductors of a phase can be fabricated from less copper, which is an expensive metal. They also achieve better thermal dissipation and current distribution and mitigate skin effects. As a result, resistive losses, which increase with increased temperature, are reduced.

Dependent claims

A bus assembly for electrical power distribution, comprising:

a first support;
a second support;
a plurality of buses each for connecting to a respective phase of a multi-phase power system, each bus comprising:
at least one first elongated conductor having a first end thereof supported by the first support and a second end thereof supported by the second support;
at least one opposing elongated conductor having a first end thereof supported by the first support and a second end thereof supported by the second support such that the at least one opposing elongated conductor, at both the first end thereof and the second end thereof, is spaced apart from and facing the at least one first elongated conductor;
at least one transverse elongated conductor situated transversely between the at least one first elongated conductor and the at least one opposing elongated conductor;
and
a connector for electrically connecting the at least one first elongated conductor, the at least one opposing elongated conductor, and the at least one transverse elongated conductor.
