EnergyConnect project is a testament to Australia’s commitment to enhancing energy infrastructure and promoting cooperation between states. This project aims to create a robust electricity transmission network, enabling the efficient sharing of power resources across three states. As Australia transitions towards cleaner and more sustainable energy solutions, the EnergyConnect project plays a pivotal role in fostering a resilient and interconnected power grid.

Dextra 的贡献

Dextra supplied a substantial quantity of GFRP rebar, showcasing its commitment to providing cutting-edge and sustainable construction materials. The use of GFRP rebar is a game-changer in the construction industry, offering a corrosion-resistant alternative to traditional steel reinforcement.

30,000 metersGFRP rebar, ranging in diameters from 13mm to 38mm, were strategically incorporated to reinforce electrical transmission linessubstation structures. This not only enhances the structural integrity of the infrastructure but also aligns with the broader goal of reducing the environmental impact of construction activities.

GFRP钢筋的优点

GFRP rebar, also known as fiberglass-reinforced polymer (FRP) rebar, offers several advantages in construction. Unlike traditional steel reinforcement, GFRP rebar is corrosion-resistant, making it an ideal choice for projects in regions with challenging environmental conditions. The EnergyConnect project, spanning multiple states with diverse climates, benefits immensely from this corrosion-resistant characteristic, ensuring the longevity and durability of the infrastructure.

Furthermore, GFRP rebar is significantly lighter than steel, simplifying transportation and handling during construction. This enhances efficiency and reduces labor costs, making it an attractive choice for large-scale projects like EnergyConnect.

弗拉芒维尔 EPR

弗拉芒维尔 EPR

弗拉芒维尔是继中国设计的100%之后,第一座采用新一代EPR设计(欧洲加压反应堆)建造的反应堆。 2019年投入使用时容量将为1.3GWe。

自 2008 年施工开始直至 2015 年,Dextra 一直在现场。

For this challenging project, Dextra has been supplying its Griptec rebar 连接方案 through its local fabricator partners. The rebar preparation was supported by an additional machine placed on site.

Griptec is the preferred rebar 连接方案 of the nuclear industry thanks to its unique performance level and an automatic testing process which systematically tests all the connections produced as part of its standard cycle: a guarantee that 100% of the connections perform above project requirement.

More than 800,000 Griptec connections have been used on the project, including 400,000 position assemblies, allowing the connection of large diameter rebar without rotating them. The Griptec connections have been installed on the reactor building and APC壳 (防飞机撞击安全壳), as well as 附属建筑.

In particular, Griptec has been used for the connections of large prefabricated panels.

阿库尤核电站

阿库尤核电站

阿库尤核电站是土耳其梅尔辛省布于克切利阿库尤的一座正在建设中的核电站。这将是该国第一座核电站。

The four 1,200 MW VVER +3 units, with a total capacity of 4,800 MW, are the world’s first nuclear power plant project implemented on BOO (建造-拥有-经营) (build-own-operate) principles by a subsidiary of Rosatom – Akkuyu NGS Elektrik Uretim AS (Akkuyu Project Company).

第一套机组的主体建设于 2018 年 3 月开始,预计于 2023 年投入运营。

第二号机组于两年后开始建设,预计将于 2024 年完工,第三号机组和第四号机组将分别于 2025 年和 2026 年竣工。

迄今为止,Dextra 提供了超过 700,000 个 Fortec+ 耦合器和锁紧螺母,以及杆端准备设备,供所有 4 个反应器和辅助区域使用。

Fortec+ 是一款平行螺纹机械拼接系统,专为核项目设计,用于连接 Ø12 至 50 mm(ASTM #4 至 #18)的混凝土钢筋,符合欧洲规范 2、ASME Sec III Div 2。

With the addition of a lock nut, it was fully engaged onto the extended thread of the connecting bar and helps eliminate the 残余变形 of the splice.

10 sets of bar end preparation system machines were also delivered at the site. The bar end preparation can be achieved in 3 steps: cutting the end of the rebar, 冷镦 to enlarge the sawn end of the rebar, and threading.

The Fortec+ system adds a fourth step, consisting of quality testing at the end of the rebar preparation process. The threaded bar end is tensile tested at 90% of the rebar yield strength to guarantee its performance.

欣克利角C核电站

欣克利角C核电站

欣克利角 C (HPC) 核电站是欧洲最大、技术最复杂的项目之一。

HPC 是英国一代人以来建造的第一座核电站,其建设需要高技能的劳动力以及最好的建筑和工程解决方案。

HPC 项目位于英格兰西南部的萨默塞特郡,将由两座核反应堆组成,可产生 3.2GW 的低碳电力。

The new power station is being constructed in the same area as the existing Hinkley Point A and B stations. The former ceased operations some time ago, while the latter is decommissioned in 2022.

Dextra 受托为 HPC 部件(特别是反应堆的飞机冲击保护壳)提供混凝土钢筋的机械接头。

More than 2.5 million Griptec couplers have been supplied for the construction of HPC.

Griptec is designed to comply with the most stringent project specifications, and has proven to be a popular system of choice for EPR nuclear power stations, having been used for the construction of the Flamanville 3, Taishan 1, and Taishan 2 power stations.

The Griptec mechanical splice consists of two steel sleeves which are swaged onto the end of the reinforcing bars by a specific machine that was designed and patented by Dextra.

This swaging machine incorporates a systematic, non-destructive pull test. Griptec is the only coupler system that provides an automatic quality control of each processed bar.

Besides Griptec couplers, Dextra is also supplying 3 million headed bars to the project. These are reinforcing bars that are bent on one side and fitted with an anchorage head on the other side and are used for the transverse reinforcement of concrete slabs, rafts, and walls. They allow a much faster and safer site installation than conventional double-bend bars.

When complete, HPC will provide low-carbon electricity for around six million homes.

福清5号和6号反应堆

福清5号和6号反应堆

Fuqing Reactor 5 and 6 are the first reactors of Hualong One, based on a 100% Chinese design. Each reactor has a capacity of 1,000 MW, with operations scheduled to begin in 2019 and 2022.

Dextra has been present on-site since the construction of Reactor 5 began in 2015 and is now involved in Reactor 6.

For this challenging project, Dextra has been supplying its Griptec rebar 连接方案, which is used for 钢筋连接 in the APC壳 (防飞机撞击安全壳).

Griptec is the preferred rebar 连接方案 in the nuclear industry due to its unique performance level and automatic testing process, which systematically tests all connections as part of its standard cycle—guaranteeing that 100% of the connections exceed project requirements.

More than a million Griptec connections will be used over the years for these two projects, supported by two Griptec machines installed on-site.

Dextra is also supporting the contractor teams on-site with two Dextra engineers rotating to provide operator training, setup, and preventive maintenance services. This ensures optimal production day and night, especially during peak times.

库丹库拉姆核电站 (KKNPP) 3 和 4

库丹库拉姆核电站(或KKNPP)是印度最大的核电站,位于印度南部泰米尔纳德邦蒂鲁内尔维利地区的库丹库拉姆。

Two reactors (KKNPP-1 and 2) have been operating since 2013 and 2016, respectively, while two more (KKNPP-3 and 4) are currently under construction following the groundbreaking ceremony held in February 2016.

KKNPP-3和4是俄罗斯设计的压水堆(型号VVER-1000/V-412)。这些反应堆是KKNPP-1和2的重复设计,并根据调试和运行经验反馈进行了进一步改进。

For the construction of these two units, Dextra supplied 350,000 Bartec couplers to connect rebars in the reactor building, auxiliary building, and spent fuel storage structures.

Bartec is a trusted splicing system, well-known for its high performance in tension, compression, and fatigue. It is widely used in the construction of buildings, bridges, metro systems, nuclear reactors, and more.

Unit 3 is scheduled for completion in March 2023, with Unit 4 following in the subsequent year.

Upon completion, these two reactors will add 2,000 MW of electricity to the existing units, bringing the total site capacity to 4,000 MW.
