WJ Type Socket Eye
The Socket Eye, also known as a Ball-eye Clevis, is a critical fitting or hardware in power transmission systems, specifically designed for connecting and load-transferring. It belongs to the category of clevis and tongue fittings. Its unique design allows for multi-directional movement, effectively relieving mechanical stresses generated during line operation.
Products Description
Product Overview
The Socket Eye and the ball-and-socket system it forms are the **standard configuration** for modern high-voltage and extra-high-voltage transmission lines, with extremely wide applications.
1. High-Voltage & Extra-High-Voltage Transmission Lines (HV & EHV)
This is the core application area. Socket Eyes are primarily used in "suspension strings" and "dead-end (strain) strings":
Suspension Strings:" Used on tangent (straight-line) towers to suspend the conductor via a clamp and insulator string. The Socket Eye connects the bottom of the insulator string to the suspension clamp.
2. Substation Structures
Within substations, Socket Eyes are used in insulator strings that connect and support busbars, downleads, and other conductive bundles, providing flexible connections and stress relief.
3. Catenary Systems for Electrified Railways
The support and suspension systems for overhead catenary lines in high-speed rail networks also widely use ball-and-socket connections to accommodate the dynamic movement of the train's pantograph.
4. Other Heavy-Duty Suspension Systems Requiring Multi-Axial Movement
While primarily used in the power industry, the design principle is also applicable in other industrial sectors requiring similar flexible, load-bearing connections.
