Double Circuit Lattice Tower

The Double Circuit Lattice Tower is a more compact tower type that carries two transmission circuits on one tower. It uses multi‑layer cross‑arms arranged vertically. Compared to single‑circuit towers, it greatly reduces the land footprint. This is a clear advantage in suburban areas and land‑scarce regions. Qingdao Hongyuanfeng Power Equipment Co., Ltd. manufactures Double Circuit Lattice Towers with symmetrical truss structures and clearly layered cross‑arms. All components are hot‑dip galvanized with a zinc coating of at least 86μm. This meets GB/T 2694‑2018 standards. In the Suzhou Yuexi 500kV substation project, many Double Circuit Lattice Towers were used. Data shows the corridor width is only about 40‑50 meters, almost doubling land utilization compared to single‑circuit towers. Double‑circuit towers reduce the number of tower foundations and overall project cost.

Our Double Circuit Towers cover voltage levels from 110kV to ±1100kV. The main material is Q235B or Q355B national standard angle steel. All components are bolted. The maximum horizontal tension design value is 50kN to 150kN. Maximum wind speed capacity is 35 m/s, and earthquake resistance is grade 8. The nominal height ranges from 24 meters to 57 meters. The horizontal span is typically 250‑550 meters. Our production lines include 8 fully automatic angle steel lines and 2 high‑speed drilling lines. Annual capacity is 2,000‑3,000 tons. We hold 14 patents, 2 trademarks, and 3 administrative licenses. We are certified in quality, environment, and occupational health. We are a "High‑tech Enterprise".

Our Double Circuit Lattice Towers have been used in the Jiuquan 500kV DC project and the Jiangsu‑Sichuan 800kV DC project. They are ideal for urban periphery and industrial parks where land is limited. They solve the problem of transmitting large amounts of power without taking up too much land. The double‑circuit design also reduces the visual impact of multiple tower lines.

Before the sale, our technical team provides planning and drawing support. We offer competitive quotes and help with bidding. During production, we share progress updates and coordinate logistics. We check site conditions in advance. After the sale, we offer a 2‑year warranty and on‑site installation guidance. We also conduct regular follow‑up visits.
