Sheave profile

A sheave configured to be mounted on an electrical stringing block and configured to hold a conductor therein, the conductor defining a diameter, the sheave comprising:

• a body having opposite sides and forming an outer circular circumference, the body including a central passageway extending between the opposite sides, a first centerline of the body is defined through the central passageway, a second centerline of the body is defined transverse to the first centerline, and a recess provided in the outer circular circumference of the body, the recess being formed of a curved surface when viewed in cross-section along the second centerline;
• and
• a lining provided in the recess and having an inner surface which is in contact with the curved surface, the lining having a groove formed in an outer surface thereof, the lining extending continuously around the outer circumference of the body, the lining formed of a non-conductive material,
• the groove forming a profile configured to hold the conductor therein, wherein when viewed in cross-section along the second centerline the profile comprises 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 to an outermost surface of the profile, each flared section extending outwardly at an angle between 23 degrees and 30 degrees from the second centerline, the radial section being defined by a radius which is approximately the same as the radius of the conductor seated therein,
• wherein the profile defines a depth extending along the second centerline and extending between the outermost surfaces to an innermost point of the radial section, the depth being scaled with the diameter of the conductor such that the conductor does not extend outwardly from the outermost surfaces of the profile.
