JSAK Intelligent Transmission Engineering Technology Group is a leader in the field of underground intelligent transmission in China and a pioneer in the overhead line entry industry. Since its establishment in 2000, it has been deeply involved in the transmission of power systems, and initially committed to the localized application of high-voltage and UHV cable connectors, 2016 Accelerating the deployment of GIL transmission technology (gas insulated transmission lines) since the beginning of the year, and currently forming two core businesses of "GIL engineering + cable accessories", it is currently the only national high-tech company in China that has mastered two underground transmission technologies (cable transmission + GIL transmission) at the same time Technology enterprises.
The company’s main products cover high-voltage and ultra-high-voltage cable connectors, GIL power transmission products and projects, smart substations, etc., to provide customers with overall solutions for underground smart power transmission and transformation systems, urban power overhead lines relocation and ground access, power engineering survey and design, and Construction services, urban substation construction and transformation services. The company has obvious technical advantages, participates in the formulation of industry standards, undertakes a number of key technology and product research and development projects for power grids, and has created a number of domestic and world firsts in the manufacturing and engineering of high-voltage and ultra-high-voltage underground transmission equipment.
JSAK is a pioneer in the field of GIL technology in China. In 2015, the company took the lead in developing 220kV/500kV/1000kV metal gas insulated busbars (GIL) in China, which filled the domestic and international technical gaps. Since 2016, the company has undertaken a number of GIL projects in the power generation industry and EPC industry, and successfully supported the localized application of the first 220kV GIL in power grid projects. In 2019, the company obtained a large 220kV GIL order from Luxi, setting the industry's longest three-phase common box GIL record, which strengthened the company's leading position in the GIL field. As of the end of the second quarter of 2020, GIL business accounted for 51.9% of the company's operating income.
The company has accumulated rich experience in the key technology of high-voltage and ultra-high-voltage cable connector manufacturing. The 500kV cable connector products produced broke the long-term monopoly of imported products in the field of 500kV cable systems. In the past five years, 70% of China`s 500kV cable systems The project was contracted by JSAK.
Experience and technology
The company has participated in the world`s first 1100kV AC UHV project Sutong GIL pipe gallery project, three urban power grid GIL transmission projects, power plant GIL EPC projects, and Luxi GIL transmission projects. It has accumulated rich engineering case experience in the GIL field and built About two years of reliable operation experience barriers, superimposed on the company's technology, qualifications and brand advantages, the company's leading position in the GIL field is prominent.
The GIL business continued to grow rapidly in the third quarter of 2020, and it has grown into the company's core performance driver. On October 21, 2020, the company announced that it has deeply participated in the feasibility study work in the bidding and pre-bidding stage. The total length of the tracking project is nearly 220km, which is much larger than the length of the project undertaken by the company before (about 14km in total) .
Considering that the company has strong advantages in terms of engineering case experience and historical project operation records, the above-mentioned project company expects that a larger scale and proportion will be converted into company orders.
Client Status
The downstream customers of the company's cable connection business are mainly the State Grid Corporation, China Southern Power Grid Corporation and power generation companies represented by the five major power generation groups, as well as some large manufacturing companies that build their own distribution networks.
In March 2020, the State Grid Corporation of China announced a substantial increase in grid investment for 2020. The total investment in power grid projects for the whole year will be raised from 408 billion yuan planned at the beginning of the year to 450 billion yuan, an increase of 42 billion yuan, an increase of 10.3%. State Grid said that the investment in the power grid can effectively drive social investment to 900 billion yuan, and the total amount of power grid investment and social investment exceeds 1.3 trillion yuan.
