Abstract
A yoke clamp bracket for a transformer core. The yoke clamp bracket may comprise a body portion having a plurality of center holes near each end, a plurality of slots for coil barriers, a plurality of slots for wiring, and attachment points for side brackets and vertical supports. The yoke clamp bracket may be mounted to a transformer core by connectors extending through the plurality of center holes. The yoke clamp bracket may be constructed from a lightweight material with low density such that it displaces a larger quantity of tank oil and reduces the weight of a distribution transformer.

A yoke clamp bracket for a transformer core, comprising:
- a body portion, the body portion including a front and back face, a top and bottom face, and a left side and right side face disposed respectively at left and right ends of the body portion;
- the body portion further having a plurality of center holes disposed in close proximity to either end of the body portion, the plurality of center holes extending through the body portion in a direction perpendicular to the planes of the front face and the back face;
- the body portion further having a first coil barrier slot and a second coil barrier slot extending inward from the top face of the body portion, the first coil barrier slot being located at a point approximately equidistant from the second coil barrier slot and the left side face, the second coil barrier slot being located at a point approximately equidistant from the first coil barrier slot and the right side face;
- the body portion further having a plurality of vertical slots, each of the vertical slots extending inward from the bottom face of the body portion, and a plurality of horizontal slots, each of the horizontal slots extending inward from the front face of the body portion, wherein at least a vertical slot and a horizontal slot are located on each of the left and right sides of the first coil barrier slot and in close proximity to the first coil barrier slot, and wherein at least a vertical slot and a horizontal slot are located on each of the left and right sides of the second coil barrier slot and in close proximity to the second coil barrier slot;
- wherein the body portion is constructed from a substantially rigid, lightweight, and non-conductive material.
