EnergyConnect - สถานีย่อย Whittens Buronga

ระบบ EnergyConnect project has emerged as a groundbreaking initiative that will revolutionize the sharing of electricity between New South Wales (NSW), Victoria, and South Australia. At the heart of this transformative project lies Dextra’s indispensable contribution—supplying almost 30,000 meters of glass fiber-reinforced polymer (GFRP) rebar in diameters of 13mm, 25mm, and 38mm. This not only marks a monumental step in the realm of construction but also advances the vision of a more sustainable and interconnected future.

ระบบ 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.

ผลงานของ Dextra

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

ระบบ 30,000 meters of เหล็กเส้น GFRP, ranging in diameters from 13mm to 38mm, were strategically incorporated to reinforce electrical transmission lines และ substation 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.

ข้อดีของเหล็กเส้น GFRP

เหล็กเส้น GFRP, also known as fiberglass-reinforced polymer (FRP) rebar, offers several advantages in construction. Unlike traditional steel reinforcement, เหล็กเส้น GFRP 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, เหล็กเส้น GFRP 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.

The 497 MW wind farm, located between 13 and 22 kilometers off the coast of Fécamp, France, includes 71 Gravity Based Structures (GBS), each of which will support a 180-meter-high windmill. The project will generate electricity equivalent to the power needs of more than 416,000 homes.

Dextra Fortec couplers and headed bars were supplied to provide the following benefits:

Fortec Couplers

Used for temporary openings to facilitate the movement of materials and personnel during various stages of construction.
ทำหน้าที่เป็นคานสตาร์ทผนังคอนกรีตเพื่อเชื่อมต่อกับคานต่อเนื่อง
Enhanced constructability by supporting climbing formwork, enabling faster GBS building cycles.
Improved rebar congestion by preventing overlapping splices.

Dextra couplers utilize Parallel Thread technology. The same couplers are used for both standard connections (when the continuation bar can be rotated) and position connections (when neither bar can be rotated). For the Fécamp project, the site was equipped with threading equipment sets.

เหล็กเสริมปลายหัวขยาย (Headed Bars)

Improved buildability and on-site productivity by reducing rebar congestion and the steel-to-concrete ratio.
Served as shear wall cross ties, offering an alternative to rebar with hooked anchorage.
Suitable for sequenced concrete pours and seismic design.
Quick to install, reducing labor and crane time.
The head can be removed for easier rebar positional adjustments.
Enhanced concrete compaction and surface quality, minimizing honeycombing.

เด็กซ์ตร้า headed bars were used as an efficient solution for the vertical การเสริมแรง of the foundation. They serve as an excellent alternative to standard เหล็กเสริมปลายงอ, which are challenging to install, especially when bent on both ends. They also replace the need for a bonded length of straight or bent rebar used for anchorage.
