Jumper Yoke Plates are specialized string hardware components used in overhead power line construction to connect and bundle multiple conductors. They enable the assembly of insulator strings on deadend towers, allowing two, three, or four conductors to be grouped with a single set of insulators. These plates attach to I-string insulator assemblies and can accommodate hold down weights for added stability in both tension and suspension configurations.
The plates are manufactured from aluminum alloy, ductile iron, or hot-dip galvanized steel. Aluminum variants provide an optimal strength-to-weight ratio, ductile iron delivers high tension strength and ductility, while hot-dip galvanized steel ensures corrosion resistance across diverse environmental conditions.
Technical specifications include ultimate strength ratings reaching up to 40,000 lb, with plate thickness of approximately 0.75 inches. Groove diameters are customizable between 1.1 and 2.5 inches to accommodate various conductor sizes, and hold down weights can be added in 50-pound increments. The design supports adjustable yoke tension and can be configured to meet specific operational requirements.
Catalog numbering systems facilitate product selection, such as the JY3 series for three-conductor models (example: JY3-1.108-01-400 for Drake conductor applications) and configurations like YPJ21018215, ensuring compatibility with international electrical power industry standards.
