| Bus Conductor: Channel Bus Conductor |
|
This Channel, which is really a pair of channels forming a hollow, ventilated square, is a practical choice for high-amperage direct or alternating current above 2,000 amperes per circuit. The aluminum channels may be placed back-to-back forming a conductor for applications such as d-c circuits, where skin effect is not a factor. For enclosed station bus where the space occupied by the conductor is critical, channel shapes of uniform thickness may be used. When the channels are assembled in pairs to form open tubes, they offer several advantages: high alternating-current ratings, high structural strength, flat outside surfaces and virtually unrestricted interior cooling.
