What is the purpose of a sweep elbow in conduit systems?

The purpose of a sweep elbow in conduit systems is to allow for a smoother change of direction. This type of fitting is designed with a gentle curve that minimizes resistance to the flow of wires or cables passing through the conduit. By providing a gradual bend, sweep elbows help to reduce friction, which can lead to less wear on the insulation of the cables and facilitate easier pulling during installation.

In contrast, other options involve either sharp angles, which are not suitable for a sweep elbow, or functions that do not align with its primary design purpose. While support structures and connections between different sizes of conduits are important aspects of conduit systems, they are not the main role of a sweep elbow. The smooth transition enabled by a sweep elbow is vital in maintaining the integrity and performance of the entire conduit system.
