‌Jiaozhou Enterprise Achieves Breakthrough: Tube Steel Positioning Patent Empowers Efficient Transmission Tower Production

Qingdao, August 6, 2025‌ – Against the backdrop of China's ongoing "Dual Carbon" strategy, Qingdao Maotong Power Equipment Co., Ltd. has successfully increased transmission tower production efficiency by 20% through its self-developed patent for a "Positioning Device for Tubular Steel Structure Processing". This innovation injects new momentum into power infrastructure construction.

‌Technical Highlight: A Leap from "Manufacturing" to "Intelligent Manufacturing"‌

The patent addresses industry pain points like slow feeding positioning and difficult finished product unloading in traditional tube steel processing through an innovatively designed L-shaped groove, hydraulic drive system, and modular clamping structure. Test data shows the new device reduces single-piece processing time to 15 minutes while lowering manual intervention risks by over 50%. The company's Technical Director revealed the technology has been applied in supplying towers for the Shandong-Jiangsu Ultra-High Voltage (UHV) project, with projected annual production cost savings exceeding 3 million yuan.

‌Corporate Strength: The Growth Code of a "Specialized, Refined, Unique and Innovative" Benchmark‌

As one of Jiaozhou City's first "Specialized, Refined, Unique and Innovative" certified enterprises in 2024, Maotong Power has established a closed-loop "R&D-Patent-Commercialization" system:

1. Accumulates 25 patents covering core areas like tower structural design and CNC production line control

2. Annual production capacity exceeds 60,000 tons of transmission towers, serving leading clients including State Grid and China Southern Power Grid

3. Co-established the "Intelligent Power Equipment Joint Laboratory" with Qingdao University to accelerate technological iteration

‌Industry Impact: Driving Green Energy Infrastructure Upgrades‌

Experts from the China Electricity Council stated such technological innovations will directly support achieving the grid construction goals of the 14th Five-Year Plan. Maotong Power plans to commission an intelligent welding production line in the fourth quarter of 2025, further responding to national demands for low-carbon and high-efficiency power equipment.

‌Looking Ahead:‌ Chairman Wang Zongfu stated the company will maintain its focus on positioning as a "smart transmission solution provider", with R&D expenditure projected to increase to 8% of revenue by 2026, contributing Jiaozhou's strength to the construction of the new power system.
