1. Connection Function
Primarily used to link insulators with fittings such as right-angle suspension plates, it serves as a critical connection point in insulator strings for overhead transmission lines, enabling the suspension or fixation of conductors on utility poles or towers. This modular connection ensures the mechanical integrity of the entire overhead system, facilitating the assembly of insulator strings and supporting components.
2. Load Transmission
It bears the responsibility of transferring the gravitational force, tension, and wind loads of conductors to the poles or towers, maintaining the mechanical balance of the line and ensuring stable operation under various working conditions. The clamp’s high-strength structure efficiently distributes dynamic and static loads, preventing stress concentrations that could lead to structural failures and ensuring the line’s stability during extreme weather events.
3. Adaptation to Line Movements
The ball-head design allows the insulator string to rotate freely within a specified range, accommodating conductor displacements caused by thermal expansion/contraction, wind galloping, or other factors. This flexibility relieves additional mechanical stress on the line, preventing damage from excessive strain and enhancing the safety and stability of the transmission system—particularly in long-span lines or regions with significant temperature fluctuations or high wind speeds.
