JSAK Intelligent Power Transmission Technology Group was founded in 2006 and is currently the only national high-tech enterprise in China that has mastered two underground power transmission technologies (cable transmission and Gas insulated metal enclosed transmission line (GIL) transmission) at the same time.
JSAK has created a number of domestic and world firsts in the manufacturing and engineering construction of high-voltage and ultra-high-voltage underground transmission equipment. The main products are: Gas insulated metal enclosed transmission line (GIL), cable connector, Cable support fixing system
Provide customers with a full ecological service of underground power transmission including consulting, design, construction, operation and maintenance and supporting financial services. JSAK undertook the first domestic general contracting project of 330kV and 500kV cable lines in the cable industry, and realized the domestic application of the first set of 330kV and 500kV cable connectors; undertook the construction of the world's largest vertical shaft cable with a drop of 462 meters and contracted domestic 500kV cables The cable engineering construction with the maximum angle of the inclined shaft (45°).
JSAK successfully developed 1000 kVGIL and 220kVGIL (three-phase common tank), obtained the world's first type test report, and took the lead in realizing the first localized application of 220kVGIL in power grid projects.
