ABSTRACT:
A cast bus bar clamp with perimetric ribs and a connecting web is provided. The design eliminates abrupt changes in cross-sectional area. This, in turn, provides a less abrupt temperature gradient on cooling which, in turn, minimizes nonuniform solidification which, if present, frequently causes the formation of weakening cracks. To improve the distribution of clamping pressure, the clamp is usually given a convex curvature so that when the clamp is tightened there are five pressure points. The design provides an improved strength-to-weight ratio and a more reliable and economical structure.
