Zhejiang Zhoushan ± 200kV Five-terminal Flexible DC Demonstration Project

It was officially put into operation on July 4, 2014. The project has completely independent intellectual property rights. It is a multi-terminal flexible DC project with the largest number of terminals and the highest voltage level that has been put into operation. It marks that my country is at the forefront of the world's flexible DC transmission technology. The successful operation of the Zhoushan multi-terminal flexible and straight project has realized the flexible conversion and mutual allocation of electric energy between islands in the northern part of Zhoushan, providing a strong electric energy guarantee for the development of the Zhoushan Islands New District.

Guangdong Shantou Nan'ao ± 160kV Multi-terminal Flexible HVDC Transmission Demonstration Project

The project was officially put into operation on December 25, 2013, and is the world's first multi-terminal flexible DC transmission project. Another major innovation in the field of international DC transmission provides safe and efficient solutions for long-distance large-capacity transmission, multi-DC infeed, and construction of DC transmission networks, and promotes new breakthroughs in international DC transmission technology.

Zhangbei Flexible DC Project

Zhangbei Project will take the lead in studying DC power grid technology in the world. For the first time, it will build a four-terminal flexible DC ring power grid, raise the flexible DC transmission voltage to 500 kV, raise the rated capacity of single converter to 1.5 million kW, and develop and apply key DC power grid equipment such as DC circuit breakers, converter valves, control and protection for the first time.

High Performance SMC Molded Parts

The high-performance glass fiber reinforced plastic (SMC-300) molded parts developed by our company are used in military short pulse width electromagnetic drive devices. Characteristics: high temperature resistance 180 ℃ (ordinary SMC155 ℃), impact resistance through the examination of 200 high-voltage short-circuit discharge tests [actual tests reached 270 times (ordinary SMC100 times)]]. The shock wave pressure is as high as 200GPa, and the tolerance is very excellent.
