Introducing the innovative high-tech Composite Core, a state-of-the-art, lightweight, and exceptionally strong core crafted from a blend of carbon and glass fibers and engineered through the advanced pultrusion process, this core is specifically designed for application in overhead conductors. Boasting a unique hybrid structure, its density is impressively 70% lower than that of a traditional steel core. Even more remarkable, when compared at equal diameters, its strength surpasses that of a steel core by an impressive 150% to 200%.
The Composite Core finds its niche in High Temperature-Low Sag (HTLS) ACCC conductors, showcasing its exceptional capabilities. Its heightened strength and reduced weight lead to a 27% increase in the cross-sectional area of the aluminium segment within ACCC conductors, outperforming both ACSR and ACSS conductors.
The Composite Core's minimal linear thermal expansion plays a pivotal role in ensuring ACCC conductors maintain negligible sag even under high-temperature conditions, setting them apart from conventional alternatives. This distinctive property makes our Composite Core-equipped ACCC conductors ideal for transmission lines characterized by extended span lengths. Furthermore, these conductors enable the use of towers with reduced height and weight, offering a compelling solution for cutting-edge transmission projects.
Another important aspect of using ACCC conductors with composite cores is the improvement in the economic efficiency of power transmission projects. Due to the increased current-carrying capacity and reduced energy loss, operational and maintenance costs over the lifespan of the lines are significantly reduced. Furthermore, the ability to use longer spans between towers and reduce the need for heavier towers leads to lower construction and installation costs. These advantages, combined with the extended lifespan of the lines, accelerate the return on investment and increase the economic attractiveness of this technology for investors and grid operators. Consequently, the use of ACCC conductors not only helps improve the technical performance of networks but also offers a strong economic justification.
Moreover, the composite core, due to its anti-corrosion properties and high resistance to harsh environmental conditions, is very suitable for use in areas with unfavorable weather conditions such as coastal and industrial areas where corrosion becomes a serious problem. These characteristics, along with low weight and high strength, increase the service life of power transmission lines and significantly reduce maintenance and repair costs. On the other hand, using this core in ACCC conductors leads to a reduction in energy loss along transmission lines, which plays a significant role in improving the efficiency of power systems.
