Recently in Hudai Town, Wuxi, the low-headroom electric construction drilling rigs in the "Five Brothers of Electric Construction" series jointly developed by TYSIM and the "Mechanized Construction Research Team" of State Grid Hunan Electric Power are promoting the efficient construction of the national project - Wuxi Huiquan-Nianhua 220 kV line project with excellent performance. This project is a key node in the upgrade of Wuxi power grid, marking a deep breakthrough of TYSIM in the field of mechanized construction of local power grids.
Technological breakthroughs in national-level projects
The Wuxi Huiquan-Nianhua 220 kV line project is a core project of the Jiangsu Province's "14th Five-Year Plan" power grid planning. The line is 16.25 kilometers long, involving 91 new towers, with a total investment of 363 million yuan. The project crosses the Meiliang Lake Scenic Area of Taihu Lake National Scenic Area and the construction control zone of Helu City Ruins, and the construction environment is complex. It places extremely high demands on the adaptability and safety of mechanized equipment. The low-headroom construction drilling rig customized by TYSIM, with its low construction height and high-torque power system, successfully overcomes the difficulties of operating under high-voltage lines and in complex strata in narrow spaces.
The innovative power of the "Five Brothers of Power Construction"
Since 2019, TYSIM has entered the field of mechanized construction equipment for power construction and created the "Five Brothers of Power Construction" series of drilling rigs, covering all-scenario models such as light, medium, heavy and low headroom. In the Changsha Huike 220 kV line project, this series of equipment set an industry record of "completing 30 days of work in 3 days", increasing construction efficiency to 40 times that of manual labor. More importantly, its design concept of "no people in deep foundation pits" successfully reduced the construction risk level of high-risk operations from level three to level four, greatly ensuring the safety of construction personnel. The low-headroom model selected for this Wuxi project continues the series' technical genes. Its multi-stage power head configuration greatly improves the efficiency of rock layer drilling and efficiently promotes the project progress.
Five years of innovation, local enterprises have a breakthrough in technology.
As an equipment manufacturing company rooted in Wuxi, the growth of TYSIM is closely linked to the needs of local power grid construction. At the beginning of 2025, the company was successfully selected as a provincial enterprise technology center in Jiangsu Province, marking that its innovation capabilities have been officially recognized by the authority. The proportion of the company's R&D investment in annual sales revenue has always remained above 5%, and it has obtained more than 60 utility models and core patents. The industry-university-research cooperation system established with universities such as Tianjin University and Tongji University provides strong academic support for technological breakthroughs. In July 2024, TYSIM's series of products were successfully selected into the first batch of promotion catalogs of the China Electric Power Construction Enterprises Association, becoming the electric power construction special equipment with the most single product types in the catalog, demonstrating its technological leadership in the industry.
As a national-level specialized and innovative "little giant" enterprise that grew up in Wuxi, TYSIM's "Five Power Construction Brothers" have been promoted and applied in power grid projects in more than 20 provinces/municipalities. In the Wuxi project, TYSIM and its wholly owned subsidiary TYSIM Rental established the "Power Grid Mechanization Construction Research Team". Through full-chain services such as equipment leasing, sales, and construction method support. And with the "Five Power Construction Brothers" as the core, a full life cycle solution covering R&D, manufacturing, and services is built. From Wuxi to the whole country, TYSIM is using technological innovation to promote the leap of power grid construction from "sweat type" to "smart type", providing solid equipment support for Chinese-style modernization.
