Angle Transmission Tower

The Angle Transmission Tower is a special tower used when a transmission line changes direction. Lines need to turn when crossing ridges, rivers, or avoiding obstacles. This tower must carry both vertical loads and the horizontal pull from the line angle. The forces on an Angle Tower are much more complex than those on a straight‑line tower. Qingdao Hongyuanfeng Power Equipment Co., Ltd. manufactures Angle Transmission Towers with thickened tower bodies and cross‑arms. We use asymmetric reinforced truss structures to strengthen the mechanical performance. All components receive hot‑dip galvanizing with a zinc coating of at least 86μm. This meets GB/T 2694‑2018 standards. Our Angle Towers support line turning angles from 0° to 90°. They can be built for single‑circuit, double‑circuit, or multi‑circuit configurations. They cover voltage levels from 10kV to ±1100kV. These towers are widely used in mountains, hills, road crossings, and river crossings.

The main material is Q235B or Q355B national standard angle steel. The maximum horizontal tension design value reaches 50kN to 150kN. The maximum wind speed capacity is 35 m/s, and earthquake resistance is grade 8. Our factory has 4 large laser cutting machines and 6 sets of 1250A automatic submerged arc welders. Our annual capacity for angle steel towers is 2,000 to 3,000 tons. Standard product delivery takes 15‑20 days. We have a strong production scheduling system to ensure on‑time delivery. Our certified inspectors conduct full quality control from material entry to final shipping. We accept third‑party inspections and provide a 2‑year warranty. We can produce according to customer drawings with a minimum order of 10 tons.

Our Angle Transmission Towers have been used in major projects such as the Jiuquan 500kV DC project, the Qinghai‑Shandong 500kV DC project, and the Jiangsu‑Sichuan 800kV DC project. Data from China Southern Power Grid shows that Angle Towers account for 10%‑20% of towers in mountain lines. In the Xinjiang Changji 220kV project, we supplied 116 towers, of which 19 were Angle Towers. Our products perform well in complex terrains. They solve the problem of line routing in areas with limited space. The asymmetric design ensures stable operation under uneven tension from both sides of the angle.

Before the sale, our technical team connects with customers. We study the project conditions, prepare plans, and handle drawing discussions. We provide reasonable quotes and answer technical questions for bidding. During production, we send real‑time updates and coordinate logistics. We also check site conditions in advance. After the sale, we offer a 2‑year warranty. We can send engineers to guide installation and solve any issues. We also conduct regular follow‑up visits to ensure customer satisfaction.
