In June 2017, Hengtong Electricity Power Industry Group - Jiangsu Hengtong High Voltage Submarine Cable Co., Ltd released the world’s longest single no joint 220kV submarine cable, and delivered the first batch of 220kV submarine cable for the Longyuan Dafeng offshore wind power project in Hengtong (Changshu) High Voltage Sea Cable Industry Park. Li Ziwei, CEO of Hengtong Electricity Power Industry Group and Wang Jian, General Manager of Jiangsu Longyuan branch witnessed the creation of new world record.
The submarine cable started production in January 2017, with a total length of production over 200km for 35kV and 220kV. It is noteworthy that the 220kV - 1*1600mm² single joint length up to 30.2km, setting the world record for the longest of the same type. Vertical cross - linking production line has a continuous boot history of 25 days, keeping the longest continuous boot record in the industry. High-voltage cable cross-linked insulation extruded volume of nearly 165 tons, which set the world record with no unusual situation. The submarine cable also passed the pressure test of 1000kW capacity and completed the pressure test for 220kV cable with 30.2 km one time, hit the high voltage test record of the marine cable industry.
It is introduced by Li Ziwei that Hentong successfully won the bid for the project with the bid amount of 280 million yuan(about $41 million) at the beginning of 2017. The delivery of the project reflects Hengtong’s technical level in the area of large cross section and large length submarine cable manufacturing, shows the equipment strength of Hengtong in high voltage submarine cable manufacturing, and demonstrates the ability of Hengtong to provide customers with system solutions.
Wang Jian says, it is very lucky to choose Hengtong as the partner. He owes to Hengtong’s great efforts for the successful delivery of the project, and hopes Jiangsu Longyuan branch can form a more extensive cooperation with Hengtong and make greater contribution to the cause of offshore wind power of China.

The offshore wind power is an important component of China's marine strategy. In the next three to five years, the country's offshore wind power projects are moving towards the coast. Hengtong High Voltage has been devoted to system solutions in the field of marine electricity power and communications transmission, and plans to continue to increase equipment investment, such as the introduction of the world's highest 32 meters vertical cable equipment. With the Longyuan Dafeng offshore wind power project as a node, Hengtong is going to challenge the longer length and larger sections with existing technology reserves to provide better guarantee for customers, and further enhance and expand Hengtong’s brand awareness and market share on global market.
