Real 640 kV cable! New HVDC XLPE technology for 8 Gigawatts power cable systems!

The proprietary Borlink? high voltage direct current (HVDC) technology has enabled the use of extruded cable technology to reach higher voltage and transmission levels than ever before. This increases the capacity, efficiency, and supply security of power networks. Beyond passing pre-qualification up to 640 kilovolts (kV), Borlink delivers superior electrical performance, and provides long-running lengths and a minimum number of joints. What is more, the cross-linked polyethylene (XLPE) material offers the additional sustainability benefit of being recyclable.

The Borlink HVDC technology has established an impressive track record. It has been selected for use in numerous projects, including a large-scale offshore wind farm in Jiangsu province of China, and several offshore projects have been energised in the North Sea recently.

More than 8,000 cable kilometres based on Borlink HVDC XLPE technology have been laid with more than 8,000 kilometres in the pipeline.

The largest ongoing Borlink HVDC endeavour at present is the German Corridors project.

This series of underground electricity transmission lines will carry power from renewable sources, such as offshore wind farms, over hundreds of kilometres with only minimal losses. Insulated XLPE underground cables made with a fully compounded HVDC cable material based on Borlink technology, at a voltage level of 525 kV, will be used in the majority of this large-scale project, specifically in the “SuedLink” and “SuedOstLink” portions.

The SuedLink has two power cable systems, each with 2 gigawatts (GW), and a cable length of over 2,500 km. The northern stretch of the SuedOstLink corridor has one 2 GW circuit and approximately 500 km of cable. Once completed, the German Corridors will have the capacity to transport 8 GW of green energy from the north to the south of Germany. This is comparable to the amount of power produced by 7-8 nuclear power reactors or as an example roughly twice the power need for Denmark.

Borouge’s High Voltage cable insulation grade secures Pre-Qualification Test Certifications

Another notable milestone, the Borouge-manufactured Borlink? LS4201S has successfully passed Pre-Qualification Tests from leading test establishments, KEMA Labs and China Electric Power Research Institute (CEPRI). Passing the rigorous standards of KEMA Labs and CEPRI at 220 kV validates Borouge as a reliable supplier for high voltage cables. Intended for power cable applications in high stress HV applications with rated voltage up to 230 kV, Borlink LS4201S will meet the increasing demand for advanced high-quality energy solutions in the global market.
