Seamless Bus Pipe
Seamless bus pipe is an extruded tubular product used to convey electricity. It is manufactured to a "nominal," not actual, inside diameter. The wall thickness is described by a "schedule." The schedules are determined by the American Standards Association.

Rectangular Bar
Rectangular shapes are the all-purpose rigid conductor for switchgear, control apparatus and busways. The use of multiple bar bus can provide a large surface area for heat dissipation. Joints and taps are easily made by bolting or welding; it is also easy to make off-sets and 90-degree bends.

Integral Web Bus Conductor (IWBC)
This shape is used for station bus, open or enclosed and for the high-current bus of outdoor substations for distribution voltages, as well as for 600-volt bus for industrial plants. ACA offers the integral web bus conductor in both ventilated and non-ventilated conditions.

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.

Bus Square Tube
This type of bus has low skin-effect ration much like that of round tubes, with the additional advantage of requiring simpler adapter plates for mounting on pedestal insulators. It is often used for generator phase and station bus in protected enclosures.

Universal Angle Bus Conductor (UABC)
The universal angle bus conductor is used for moderate-size outdoor substations at distribution voltages. Centerline grooves make it easy to locate bolt holes. The bus can be mounted directly on insulator caps, since both legs are of uniform thickness.
