Ball-head Hooks For Power Line Connections
Ball-head hooks, also commonly known as question mark hooks, are indispensable forged connection fittings for overhead power transmission and distribution lines. They primarily function as connection and suspension links between insulator strings and various other fittings, and are widely used in power engineering projects such as power distribution line construction and line upgrades.

01
The product is integrally forged using a single die-forging process, eliminating any welded seams. Its dense internal structure provides excellent impact and fatigue resistance, allowing it to stably bear static and alternating loads during line operation. This eliminates the risk of welded joint fracture, ensuring long-term safe operation of the line.
02
Hot-dip galvanizing provides corrosion protection with a uniform and strong coating, resisting outdoor rain, humidity, and salt spray corrosion. It adapts to complex and harsh outdoor environments, extending the product's service life.
03
The ball head end can be directly matched with the insulator ball socket interface. The hook portion is used to connect accessories such as hanging rings and suspension wires. It is widely applicable to high-voltage power transmission and distribution lines, used in overhead power lines, connecting insulators, suspension clamps, and tension components, enabling rapid assembly and connection between fittings.
04
It also offers a variety of standard specifications to choose from, and supports non-standard customization according to customer drawings and technical parameters. The products undergo load testing before leaving the factory, and their mechanical properties are stable and reliable. They are very commonly used connection accessories in overhead power engineering projects both domestically and internationally.

About Cast Connector Rings / ADSS Extension Connector Brackets
ast connector rings and ADSS extension connector brackets are indispensable auxiliary accessories in the construction of power communication lines, widely used in the installation and maintenance of optical cables. As high-strength, high-reliability connection components, these two products play a crucial role in ensuring the safe and stable operation of optical cable lines and improving the overall durability of the system.
I. Cast Connector Rings
Manufactured using high-quality alloy materials and precision casting processes, these rings are characterized by their robust structure and high load-bearing capacity. Their main function is to connect and fix various metal accessories and supports during the installation of overhead optical cables, ensuring the mechanical stability and wind and earthquake resistance of the optical cable system. Their surface is treated with anti-corrosion coating, effectively resisting corrosion and wear in harsh environments and extending the service life of the equipment. They are also designed to meet industry standards, are easy to install, and ensure a tight and reliable connection when used with other accessories.


II. ADSS Extension Connector Brackets
ADSS extension connector brackets are specifically designed for the extension and connection needs of self-supporting insulated overhead optical cables. They are mainly used to extend the suspension distance of the optical cable or adjust the installation angle of the optical cable. The bracket is made of high-strength alloy material, possessing excellent mechanical properties and UV resistance, adapting to various complex climatic conditions. Its scientifically designed structure allows for simple and quick installation, significantly saving construction time and labor costs. Using the ADSS extension connector bracket effectively improves the tensile strength and stability of the optical cable line, reducing the risk of damage caused by environmental factors.
