Recently, Hengtong High Voltage successfully delivered the 220kV large cross-section smooth aluminum transmission system for the Huaneng Shantou Lemmen Offshore Wind Power Access System Project, which smoothly passed the withstand voltage test. This marks a new system solution provided by Hengtong for high-voltage power transmission in China.
Due to the project's requirement for a large transmission capacity and the influence of factors such as laying methods and environmental conditions, conventional transmission systems could not meet the project's needs. Therefore, Hengtong High Voltage organized professional technical forces to conduct in-depth research and improvement on product structure, materials, and manufacturing processes, successfully developing a 3000-section large specification 220kV smooth aluminum transmission system. This system has the advantages of compact structure, large transmission capacity, excellent water resistance, high safety, and strong stability. Combined with a new type of laying scheme using low thermal resistance filling materials, it significantly improves the transmission capacity and ensures the project's capacity requirements.
Through various tests and international application cases, this smooth aluminum transmission system can further enhance the safety and stability of the power grid lines, ensuring the electricity supply for urban production and daily life, and meeting society's ever-increasing demand for electric power energy. At the same time, the project's adoption of the large cross-section smooth aluminum transmission system combined with a new capacity-increasing scheme using low thermal resistance filling materials also provides a new technical solution for offshore wind power access systems.
Hengtong, with its modern manufacturing equipment and detailed process control, ensures the excellent quality and delivery progress of the products, fully demonstrating Hengtong's development philosophy of "technology innovation" as the primary driving force. In the future, Hengtong will continue to establish its brand with quality, win a reputation with services, promote industry development, assist marine energy, and leave more Hengtong marks in the blue ocean.
