A few days ago, the new high-strength invar newly developed by HBGT Steel Technology Corporation was successfully commercialized, and received orders from many high-end cable/double-capacity conductor manufacturers. This marks the product's official entry into the high-end power transmission wire market, breaking the monopoly of a very few foreign companies on the domestic market.
New high-strength invar products are the most advanced core and key materials for manufacturing double-capacity power transmission wires.
In 2021, HBGT is the first to develop this product using nano-scale composite second-phase particle precipitation technology. After testing by the State Grid, key performance indicators such as tensile strength, thermal expansion coefficient, and torsional turns have reached the international leading level.
In the process of research and development, HBGT has carried out refined management and control of the entire industrial chain, and has successively completed independent design of the composition system, cracked key technologies of a series of processes, mastered the integrated manufacturing technology of double-capacity conductors, etc., and has the mass production capacity of new high-strength Invar products.
