Borouge and Borealis help the largest single-scale cable project in China

With the rapid growth of the domestic economy and the development of urbanization, the demand for underground cables for large-capacity power transmission lines in cities continues to increase, so the demand for safe and reliable ultra-high voltage cable solutions to support important power transmission projects has also increased accordingly
.

The largest single-scale cable project in China

With more than 50 years of successful development and application in cross-linked polyethylene (XLPE) solutions, and more than 20 years of experience in extra-high voltage cross-linked polyethylene (EHV XLPE) (especially low scorch insulation solutions in EHV power cables) application in length production), Borouge and Borealis provided land cable power transmission support for the relocation and landing project of the 330kV overhead transmission line in the northeast of Xi'an
.

According to reports, the relocation and landing project of the 330kV overhead transmission line in the northeast of Xi'an is the largest single-scale cable project in China
.

The project is committed to opening up the 330kV overhead line corridor in the northeast of Xi'an and providing safe and sufficient power protection, and supplying power to the surrounding important infrastructure facilities such as the Xi'an Olympic Sports Center for the 14th National Games in 2021; in addition, the project also The urban power grid will be strengthened to serve key areas such as the Convention and Exhibition Center, the Conference Center, the International Port Area, the Economic and Technological Development Zone, and the Chanba Ecological Zone
.

After the project is completed, it will beautify and improve the urban landscape, improve the reliability and safety of regional power supply, and drive the economic development of Xi'an
.
The project will become a benchmark for the design, construction, operation and maintenance of China's future long-distance ultra-high voltage cable projects
.

Large scale and high technical complexity

As a leading enterprise in the international cable industry, Qingdao Hanhe was designated to design, manufacture and install 62 kilometers of 330kV EHV cables in this relocation project
.

However, the project brought many challenges, for example: there is no direct reference standard for the design and development of 330kV cables in the country that can be used as a guide
.
The construction period is short and the construction is difficult (due to the cables passing through the existing subway, high-speed train and overpass network and the area under the river)
.
The construction of the country's first ultra-high voltage power grid system for reactive power compensation and overvoltage control is a large-scale project with high technical complexity
.

High requirements for insulation and electrical shielding materials

After cooperating with Borouge and Borealis on the State Grid Land Cable Strategic Project, Qingdao Hancang once again selected Borouge and Borealis' cable insulation material Borlink™ LS4201EHV and semi-conductive shielding material Borlink™ LE0500 to meet the challenges of this project
.

It is understood
.
The Borlink™ LS4201EHV is a good choice for insulation in complex applications such as EHV power cables and is tailored for high field strength high voltage applications with rated voltages above 230 kV
.

Produced under extremely stringent cleanliness requirements, Borlink™ LS4201EHV provides XLPE cable manufacturers with design flexibility, excellent scorch safety and excellent performance with low outgassing burden
.

The Borlink™ LS4201EHV has a low risk of insulation defects and short degassing times, allowing Qingdao Hanhe to optimize production cycle times and achieve just-in-time delivery of EHV power cables while maintaining high quality standards
