Tension towers are the core load-bearing components of overhead transmission lines. They are mainly used to anchor conductors in sections, control line tension, divide tension sections, limit the spread of wire break accidents, and ensure the safe and stable operation of transmission lines.
Qingdao Anbang New Energy, as a national high-tech enterprise, a reliable manufacturer and supplier in China, focuses on the research, development, manufacturing, and full-process service of tension towers. Our products cover all voltage levels from 35kV to 220kV and include various types such as angle steel tension towers and steel pipe tension towers.
Strictly following the general design specifications of the State Grid, the towers are suitable for main grid lines, crossings of roads and rivers, and complex terrains such as mountains and hills. They are widely used in domestic grid upgrades, rural network transformations, and supporting new energy transmission projects. With fine quality and efficient service, the company has become a preferred supplier for power engineering projects.

The tower body uses a thickened angle steel truss structure, with larger component specifications and denser bolted joints. The overall stiffness, tensile resistance, and anti-overturning performance far exceed conventional straight towers.
It can evenly bear the bidirectional tension of conductors and ground wires, effectively segment tension areas, lock line tension under wire breakage or tightening conditions, prevent accident propagation, and ensure overall line safety.
Strictly follows the "Steel Structure Design Standard" and "General Design of Transmission Line Towers." High-quality national standard carbon structural steel is selected for raw materials.
CNC cutting, precision punching, and automated welding ensure accurate dimensional tolerances and high fit of tower assembly.
Factory load verification and stress testing are fully covered, meeting grid connection acceptance standards.
All tower components adopt overall hot-dip galvanization, with a uniform and dense zinc layer offering strong resistance to acid rain, coastal salt spray, and corrosion in humid mountainous areas.
No frequent rust removal or repainting is needed, and outdoor service life can reach 50 years, reducing full-cycle operation and maintenance costs.
Suitable for flat land, hills, mountains, marshes, complex high-speed or river-crossing conditions. Tower height, cross-arm dimensions, leg spacing, and load levels can be customized as needed.
Adaptable to different weather conditions (high wind, icing, extreme cold) to meet diverse grid construction requirements.
The entire tower uses bolted assembly connections with no on-site welding. Standardized component segmentation allows easy transportation and fast on-site hoisting and assembly, significantly shortening project duration.
Accompanied by a full set of high-strength tension fittings and jumper structures, installation is standardized and worry-free.
Anbang is a Qingdao-based local power steel structure factory, covers 150,000㎡, producing over 50,000 tons of tower components annually.
Offers one-stop turnkey services including design, customized production, logistics, on-site installation, and after-sales maintenance, with ample stock and stable delivery cycles.
Structurally adopts a short and sturdy reinforced design, with a steep tower slope and wide base section providing excellent torsion and uplift resistance. Reinforced tension cross-arms adapt to diagonal insulator string anchorage, with stable tension transfer, bearing vertical loads, horizontal wind loads, and longitudinal line tension, achieving integrated multi-load bearing.
Typical applicable scenarios include:
Overhead transmission line sectional anchoring nodes
Long-distance line tension demarcation points
Both sides of significant crossings such as railways, highways, rivers, and canyons
Small-angle line transition sections
Grid terminal access points;
National and local grid renovation
Rural grid transformation
Photovoltaic/wind power supporting transmission projects.
