The Zinc - 5% Aluminium - Mischmetal alloy coating, commonly referred to as Galfan, represents a specialized protective layer applied to steel wires utilized within the core of overhead conductors. Notably, Mischmetal, an uncommon rare earth element, contributes to the distinctive properties of this coating. Galfan coating synergistically harnesses the anti-corrosion attributes of both zinc and aluminium, yielding a unique combination that bestows exceptional resistance to rusting.
One of Galfan's defining advantages is its augmented resistance to rusting and enhanced thermal resilience, which stands at least twice that of conventional galvanizing coatings. This elevated resistance translates into a remarkable doubling of the lifespan of Galfan-Coated steel wires in comparison to their galvanized counterparts. As a result, the application of Galfan-Coated steel wires is particularly recommended, especially in environments characterized by pollution and corrosion.
In the contemporary landscape, the utilization of Galfan-Coated steel wires has gained prominence, notably in Iran, where these wires are commonly integrated into the core of Aluminium Conductor Steel Supported (ACSS) conductors. This strategic integration underscores the enduring popularity and practicality of Galfan-Coated steel wires, further reinforced by their ability to withstand challenging environmental conditions while significantly extending the operational lifespan of overhead conductors.
Galfan-Coated steel wires, due to their superior performance and longer lifespan, can play a significant role in reducing maintenance costs of power transmission systems. Given the increasing demand for improved efficiency and reliability of equipment in the power industry, further research is being conducted to optimize and expand the use of alloy coatings like Galfan. This ongoing research is expected to lead to more innovations in this field.
