Rectangular yoke plates terminate two-conductor bundles in overhead power transmission deadend applications using a double string of insulators. Manufactured from galvanized steel or ductile iron, these plates resist moisture, corrosion, and wear in outdoor utility and industrial environments. Galvanized coatings enhance weather resistance, while ductile iron provides robust mechanical properties for demanding loads.
Ultimate strength ratings range from 30,000 to 100,000 pounds across different models. Standard configurations feature 18-inch hole spacing for insulator attachment, with plate thickness between 0.63 and 0.75 inches. Many designs include four 0.500-inch cap screw holes for mounting corona rings to support electrical performance.
Dimensional specifications include lengths up to 21 inches, widths around 9 inches, and weights from 24 to 36 pounds. Insulator attachment holes measure 0.688 to 1.063 inches in diameter, while conductor attachment holes range from 0.938 to 1.188 inches. Original Equipment Manufacturer (OEM) services enable customization of size, hole spacing, and strength requirements to meet specific application needs.
