Guangdong Xinyuan Hengye Power Transmission Device Co.,Ltd.
From 7-strand to 61-strand carbon fiber cores, every strand is twisted with our love and responsibility for customers.
Founded in 2009, Guangdong Xinyuan Hengye Power Transmission Device Co., Ltd. is situated in Shijiao Town, the county seat of Fogang County, Qingyuan City, Guangdong Province, boasting convenient transportation access—it is merely 1 kilometer away from National Highway 106 and 3 kilometers from the Beijing-Zhuhai Expressway. Seizing the opportunities brought by the "11th Five-Year Plan" power grid planning and the construction and renovation of large-capacity transmission lines, the company has continuously increased investment in scientific research and is dedicated to the R&D and production of carbon fiber composite technology, energy-saving and environment-friendly overhead transmission conductors, as well as special wires and cables.
As the only high-tech enterprise in China specializing in the design and manufacture of stranded carbon fiber composite core conductors and hardware fittings, our company is capable of producing 7-strand, 19-strand, 37-strand, and 61-strand carbon fiber cores, along with various specifications of stranded carbon fiber composite core conductors ranging from 95/20 to 2000/400 mm². These conductors can significantly enhance current-carrying capacity and are characterized by high strength, high temperature resistance, stable tensile strength, and slow elongation. Additionally, they possess advantages such as small sag, light weight, corrosion resistance, low line loss, and high conductivity. Covering an area of 182 mu (approximately 121,333 square meters), the company has an annual production capacity of 10,000 kilometers of stranded carbon fiber composite core conductors. The supporting strain clamps and splicing sleeves adopt an original crimping method, making them particularly suitable for critical lines including new construction, capacity expansion and renovation, extra-large crossings, ultra-high voltage (UHV), and extra-large cross-section projects.
In 2024, Guangdong Xinyuan Hengye increased its capital in Guangzhou Xinyuan Hengye Power Transmission Equipment Co., Ltd. by RMB 86.2299 million through subscription. After the capital increase, it holds a 60% stake in Guangzhou Xinyuan, achieving asset restructuring and thereby inheriting Guangzhou Xinyuan's hardware fitting qualifications and project performance. As one of the first domestic manufacturers supplying transmission line hardware fittings for UHV projects, Xinyuan Hengye has long served major clients such as the State Grid Corporation of China, China Southern Power Grid, and Inner Mongolia Power Group. In recent years, it has provided products for over 1,000 power transmission and transformation projects at home and abroad, including those in Poland, Spain, Vietnam, Laos, and other countries. Since 2009, the company has supplied transmission line hardware fittings for 15 domestic UHV line projects, covering both DC and AC systems.
We provide comprehensive solutions for power transmission and communications projects worldwide. Backed by cutting-edge technologies and proven product performance, we are committed to meeting our clients’ diverse needs and driving innovation across the industry.

From 7-strand to 61-strand carbon fiber cores, every strand is twisted with our love and responsibility for customers.
As the only high-tech enterprise in China specializing in the design and manufacture of stranded carbon fiber composite core conductors and hardware fittings, Xinyuan Hengye has built an integrated modern production line featuring "precision R&D, intelligent production, and strict testing." Within the 182-mu production base, the production lines are scientifically laid out and smoothly connected. Relying on standardized processes and intelligent equipment, the annual output of stranded carbon fiber composite core conductors reaches 10,000 kilometers, accurately meeting the needs of high-end power transmission projects worldwide.
The production line takes quality as the core starting point and establishes a full-process traceability and testing mechanism. For core raw materials such as carbon fiber filaments and aluminum alloy rods, advanced equipment is used to conduct comprehensive screening of key indicators such as strength, corrosion resistance, and electrical conductivity. Then, refined pretreatment such as precise cutting and surface treatment is carried out to lay a solid foundation for the quality of subsequent production.
The core workshop is equipped with customized intelligent stranding equipment, which can accurately produce multi-specification carbon fiber composite cores such as 7-strand, 19-strand, 37-strand, and 61-strand. During production, parameters such as stranding tension and spacing are monitored in real time to ensure stable core performance; subsequently, an independently developed precise temperature-controlled curing process is adopted to endow the product with excellent high-temperature resistance and anti-aging characteristics.
The cured composite core is accurately stranded with pretreated aluminum alloy strands. The intelligent equipment can adapt to the needs of different cross-sectional specifications from 95/20 to 2000/400mm², realizing automatic wire arrangement and stranding. The whole process is visually monitored, and parameters are recorded in real time for traceability, balancing production efficiency and quality consistency.
A dedicated production line for hardware fittings and splicing sleeves is set up, with the core application of original crimping technology. Customized equipment works in coordination to complete the full-process standardized production from hardware blank processing, surface anti-corrosion treatment to precise crimping. It can automatically match adaptation parameters of different specifications to ensure uniform crimping strength and reliable connection, meeting the needs of important lines such as new construction and UHV projects. Each hardware fitting undergoes multiple precision and strength tests to ensure no quality defects.
The finished product testing workshop is equipped with advanced domestic and foreign equipment, building a comprehensive performance testing system. For finished conductors, core indicators such as current-carrying capacity and high-temperature resistance are tested; for hardware fittings, key tests such as crimping strength and corrosion resistance are carried out. All finished products must pass multiple tests before leaving the factory. Test data is real-time recorded into the system to form a full-process traceability file, demonstrating the factory-building policy of "surviving by quality" and consolidating the foundation of customer trust.
From raw materials to finished product delivery, Xinyuan Hengye's production line is not only an intelligent manufacturing platform but also a practice carrier of the concept of "developing through science and technology and taking service as the foundation," contributing to global power grid construction with ultimate quality.
