220kV Transmission Line Angle Steel Tower

The 220kV Transmission Line Angle Steel Towers of Qingdao Anbang New Energy are manufactured with the support of Qingdao Jiaozhou Modern Chemical Plant. They use high-strength angle steels such as Q355B and Q420, with a lattice bolt connection structure.

Designed and produced strictly in accordance with national and international standards, they combine high strength, high corrosion resistance, easy installation, and strong adaptability, providing stable support for 220 kV high-voltage transmission lines.

They are widely used in plains, mountainous areas, coastal regions, and various other terrains, contributing to the construction of new power systems in different countries.

Core Advantages

Maximum structural strength, outstanding disaster resistance: 220kV Transmission Line Angle Steel Tower designed with triangular/quadrilateral lattice structures, main material thickness ≥8mm, seismic resistance up to level VIII, capable of withstanding 12-level gale, 50mm ice coating, and heavy rainfall. It operates stably in coastal typhoon areas and mountainous wind-prone regions, with uniform load distribution and industry-leading anti-overturning performance.

Factory smart manufacturing with precision, quality controlled throughout the process: Qingdao Jiaozhou owns its production base, with CNC cutting, intelligent punching, and fully automated hot-dip galvanizing process, equipped with patented reinforcement, welding, and forming devices, component accuracy ±1mm, and 100% of the products pass mechanical and corrosion resistance tests before leaving the factory.

Corrosion-resistant and durable, worry-free throughout the lifespan: The tower uses a hot-dip galvanized double-layer anti-corrosion process, with a zinc layer thickness of ≥85μm, resistant to salt spray and acids and alkalis, with a service life of over 30 years in coastal humid environments, requiring no frequent maintenance, reducing total lifecycle costs.

Easy and efficient installation, suitable for complex scenarios: modular bolt connections, no need for large equipment, quick on-site assembly; tower customized design, adaptable to different terrains and weather conditions, reducing construction period by more than 30%.

Intelligent supporting upgrades, efficient and precise operation and maintenance: Optional tilt angle, wind speed, icing monitoring, and video terminals, with data accessed in real time by power grid dispatch, achieving round-the-clock status awareness and fault early warning, improving operation and maintenance efficiency by over 30%.
