1. High-Quality Materials

Typically made of hot-dip galvanized steel or other conductive metal materials. The hot-dip galvanizing process forms a dense zinc layer on the surface, effectively preventing rust and corrosion of the steel, adapting to various harsh outdoor environments, and prolonging service life. This anti-corrosion treatment ensures the clamp remains structurally sound in extreme weather conditions, such as high humidity, salt mist, or industrial pollution.

2. Rational Structure

One end is designed in a ball-head shape, which has excellent adaptability for connecting with insulator strings, ensuring a tight and secure connection that is not easy to detach. The other end is a ring-shaped joint, which can be fixed to utility poles or towers through right-angle suspension plates or similar fittings. This modular design facilitates quick assembly and ensures mechanical stability in both tension and compression scenarios.

3. High Strength

The selected steel undergoes a reasonable heat treatment process, giving it good strength and toughness. It can withstand substantial tensile forces, meeting the mechanical requirements of transmission lines during operation and ensuring reliable connections. For example, standard models can typically bear tensile loads ranging from 70 kN to 210 kN, making them suitable for various voltage classes from medium to ultra-high voltage systems.

1. Secure Connection

Both the ball-head-to-insulator connection and the suspension loop-to-other-fittings/tower connections are highly secure, resisting loosening over long-term use and reducing the risk of line faults caused by connection issues. The precision-engineered ball-and-socket interface ensures a snug fit, while anti-loosening fasteners further enhance stability in high-vibration environments.

2. Strong Versatility

Available in multiple models (e.g., QH-7, QH-10, QH-16), it can be paired with insulators and other fittings of different specifications, suitable for transmission lines with voltage classes ranging from 10kV to 330kV. This adaptability makes it a universal choice for diverse grid projects, from urban distribution networks to long-distance high-voltage lines, and complies with international standards for interchangeability.

3. Easy Installation

The structural design facilitates quick installation and disassembly, improving construction efficiency and reducing labor costs. The plug-and-play ball-head design eliminates the need for specialized tools, while standardized interfaces allow for rapid integration into insulator strings or tower structures. This feature is particularly beneficial for large-scale projects or emergency maintenance, where time savings are critical.

1. Connection Function

Primarily used to connect insulators with other fittings such as right-angle suspension plates and bowl-head suspension clamps, forming insulator strings to suspend conductors from utility poles/towers or fix them on tension towers. This modular connection creates a flexible yet secure mechanical system for overhead line installation.

2. Load Transmission

In transmission lines, it plays a critical role in transferring the gravitational force, tension, and wind load of conductors to the poles/towers, ensuring the mechanical balance of the line. The clamp’s robust structure efficiently distributes dynamic loads to prevent stress concentrations that could compromise structural integrity.

3. Adaptation to Line Movements

The ball-head design allows the insulator string to rotate freely within a certain range, adapting to conductor displacements caused by thermal expansion/contraction, wind galloping, or other factors. This articulation relieves additional stress on the line, preventing damage from mechanical strain—particularly important for long-span lines or regions with extreme temperature variations.
