Dead End Transmission Tower

The Dead End Transmission Tower is a key load‑bearing tower in high‑voltage transmission lines. Its main job is to withstand the horizontal tension of conductors and ground wires. When a line break happens, this tower limits the fault to the section between two Dead End Towers. This stops the fault from spreading further. Dead End Towers are often used at line turning points, section breaks, and line terminals. Qingdao Hongyuanfeng Power Equipment Co., Ltd. manufactures Dead End Transmission Towers using modular angle steel truss structures. The tower body is thickened and reinforced. We equip each tower with strain insulator strings and jumper systems. Every component gets hot‑dip galvanizing with a zinc coating of at least 86μm. This meets IEC international standards and GB/T 2694‑2018 requirements. The Dead End Tower carries much higher forces than a Tangent Tower. It must handle both vertical loads and horizontal tension. The cross‑arms use asymmetric reinforcement to handle single‑side or double‑side conductor pulling forces. We design each tower with line turning angles, wind loads, and ground conditions in mind. This ensures stability under complex working conditions.

Our Dead End Transmission Towers cover voltage levels from 110kV to ±1100kV. The main material is Q235B or Q355B national standard angle steel. The maximum horizontal tension design value ranges from 50kN to 150kN. The nominal height ranges from 18 meters to 51 meters. The horizontal span is typically 250 meters to 550 meters. Tower shapes include dry‑type, cup‑type, and portal‑type. We can customize the design based on project needs. Our production line includes 8 fully automatic angle steel production lines and 2 high‑speed automatic angle steel drilling production lines. Our annual production capacity for angle steel towers is 2,000 to 3,000 tons. This capacity allows us to handle large orders and deliver on time.

Qingdao Hongyuanfeng Power Equipment Co., Ltd. started in 2019. Our factory is located in Beiguan Industrial Park, Jiaozhou, Qingdao. The facility covers 151 mu and employs about 120 workers. We hold 14 patents, 2 registered trademarks, and 3 administrative licenses. We have passed quality management, environmental management, and occupational health and safety certifications. We are recognized as a "High‑tech Enterprise" and a "Qingdao Specialized and Sophisticated SME." Our certified inspectors check every production step from raw steel to finished galvanized tower. We perform 100% inspection before packing and accept third‑party inspection. Our Dead End Transmission Towers have been applied in major projects such as the Jiuquan 500kV DC project and the Qinghai‑Shandong 500kV DC project.

Dead End Transmission Towers are essential for grid reliability. They prevent cascading failures by isolating broken line sections. Our products have served the West‑to‑East power transmission project and many 500kV substation connections. In mountainous areas, these towers handle large angle turning and high tension. Our customers include State Grid and China Southern Power Grid. We provide full technical documentation for export projects. Our design follows GB50545‑2010 and IEC 60652. We can produce according to client drawings with a minimum order of 10 tons. Sample development for large custom items takes 7‑10 days.

We offer a complete service package. Before the sale, our engineers discuss project conditions and provide budget quotes. They also support tender technical queries. During production, we send progress photos and videos. We arrange shipping and notify customers of logistics status. After delivery, we offer a 2‑year warranty. We can send technicians to site for installation guidance. We also conduct regular follow‑up visits. We accept third‑party inspections and ensure all products are 100% checked before shipping.
