Abstract
A sheave is configured to be mounted on an electrical stringing block and is configured to hold a conductor therein. The sheave includes a groove formed continuously along an outer surface of a circular body. The groove has a profile which is optimized to support the conductor, such that the conductor is prevented from riding out of the profile upon rotation of the sheave. The profile includes a radial section defining a pair of tangents and a pair of flared sections extending along the respective tangents from outer ends of the radial section. Each flared section extends outwardly at an angle relative to a centerline of the body. The radial section has a radius which is approximately the same as the radius of the conductor. The profile defines a depth which is scaled with the diameter of the conductor, such that the conductor does not extend outwardly from the groove.
