1. Jumper Fixation
Primarily used to secure jumpers (drain wires) in overhead power lines to insulator strings, ensuring jumpers maintain specified positions and shapes. This meets the installation and operational requirements of electrical equipment by preventing unintended movement and ensuring proper clearances for safe power transmission.
2. Load Bearing
It bears the gravitational force of jumpers, wind load, and other environmental loads, transmitting these forces to utility poles or towers. Engineered to withstand various meteorological conditions (e.g., strong winds, temperature fluctuations), it ensures the safe suspension of jumpers and maintains the mechanical stability of the entire line configuration.
3. Electrical Performance Assurance
Through rational structural design and optimal contact surfaces, it reduces stress concentration at fixation points, protecting jumpers from mechanical damage. Meanwhile, it ensures excellent electrical connectivity between jumpers and insulator strings, minimizing contact resistance and preventing arc discharges. This design guarantees smooth power transmission, complies with high-voltage insulation standards, and enhances the reliability of the electrical system.
