Spare Launches New GFRP Power Crossarms, Pioneering Innovation in Transmission Line Materials

Recently, Spare Company officially launched a new GFRP power crossarm, bringing a material innovation to the power transmission line industry. The product is made of glass-fibre reinforced plastic (GFRP) as its core material, redefining the standards for power transmission line support structures with its outstanding performance.

This GFRP power crossarm demonstrates remarkable material properties, combining the corrosion resistance of a polymer matrix with the high strength of glass fibre reinforcement to form a lightweight, high-strength, insulating composite system. Its density is only one-fifth that of steel, significantly reducing installation and transportation costs, while its tensile strength can exceed 500 MPa, capable of reliably supporting conductors and lightning arresters. Additionally, its excellent electrical insulation properties provide a robust safety guarantee for the power lines.

In terms of product advantages, its corrosion resistance is unmatched, exhibiting high inertness to acids, alkalis, salt fog, and humid environments. In harsh environments such as coastal areas and industrial pollution zones, its service life can exceed 30 years, far surpassing the 15–20 years of galvanised steel crossarms. This reduces lifecycle maintenance costs by 40–60%, yielding significant economic benefits. What is even more noteworthy is that its production process reduces carbon emissions by 50% compared to metal crossarms and does not require polluting processes such as galvanisation, perfectly aligning with the low-carbon transformation needs of the power grid.

In terms of structural form, the product is manufactured using the pultrusion process and features various structures such as square bar, triangular, T-shaped, L-shaped, and square tube types, catering to the installation requirements of different power lines. It has a wide range of applications, suitable for high-voltage and ultra-high-voltage transmission lines, as well as special environments such as mountainous areas, marshes, and coastal regions. It effectively reduces the frequency of faults such as lightning breakdown and pollution-induced flashover, enhancing the safety and stability of transmission lines.

Spare's newly launched GFRP power crossarms undoubtedly inject new vitality into the power industry, with the potential to drive transmission line construction toward a new phase of higher efficiency, environmental friendliness, and safety.

Additionally, Spare offers customisation services, enabling personalised production based on customer requirements in terms of colour, shape, length, and width, comprehensively addressing the diverse needs of various power engineering projects.
