Y-Clevis Eye
The Y-Clevis Eye serves as an insulator fitting for attaching clamping devices to yoke plates in bundle conductor assemblies. It features a distinctive Y-shaped design with a bent bolt section that enables additional articulation points. These components excel in power transmission systems where secure connections are paramount.
Y-Clevis Eyes are manufactured primarily from ductile iron with hot-dip galvanized coating for durability. The body construction includes a curved bolt section and precision-engineered eye hole for mounting. They come in various sizes, with ultimate strength ratings ranging from 19,000 to 30,000 pounds.
These hardware fittings integrate seamlessly with standard insulator assemblies and conductor bundles. The eye opening accommodates pins ranging from 5/8 inch to 2-1/2 inches in diameter. Their versatile design allows for multiple mounting configurations in transmission line systems.
Key Features:
• Bent bolt Y-section design provides enhanced articulation flexibility
• Hot-dip galvanized finish ensures superior corrosion resistance
• Ultimate strength ratings up to 30,000 pounds for heavy-duty applications
• Precision-machined eye holes for secure pin connections
• Available in multiple throat diameters for varied insulator compatibility
