In response to the region's need for corrosion-resistant wires, the Association demonstrated the advantages of products developed by Ludinovokabel JSC in collaboration with the Institute of Lightweight Materials and Technologies (ILMiT).
An analysis of the Middle East market has shown that corrosion of uninsulated wires is a significant problem and causes additional costs for the maintenance of electrical networks.
Corrosion significantly reduces the reliability of wires and the service life of products, as well as increases their maintenance costs. The solution may be a new generation of corrosion-resistant, non-insulated AAcrCSRZ wires (high-strength steel + aluminum alloy (special type) (Z-shaped profile), created on the basis of a unique aluminum alloy X with a heavy-duty steel core coated with Al-Zn-mishmetall.
The advantage of the solution lies in a systematic approach: a special aluminum alloy with increased resistance, corrosion—resistant grease, a protected steel core and a Z-shaped wire profile that minimizes moisture penetration. The results of accelerated tests simulating the conditions of the Red Sea show that the resource of the new wire is at least 2 times higher than its traditional counterparts, which reduces maintenance costs and increases the reliability of power grids. The stable anode protection of the core provides additional reliability to the cable, reducing the risk of galvanic corrosion.
To confirm the durability of the AAcrCSRZ wire, Ludinovokabel JSC and ILMIT conducted comprehensive tests lasting 10-90 days. In the course of the research, tests were carried out with complete cable immersion in a 4.1% chloride solution (maximum salinity of the Red Sea), in climatic chambers with cycles of high temperature and humidity (tropical climate conditions), as well as in a corrosion chamber for the stability of AAcrCSRZ cable in conditions of salt fog simulating coastal marine conditions. Such thorough and intensive tests have demonstrated full compliance with the requirements and climatic conditions of Saudi Arabia.
Wires of this design have already been successfully operated in various regions, including the northern and southern sea coasts. Long-term experience shows their high reliability and durability even in aggressive conditions such as high humidity, salt exposure and strong winds. This fact confirms that the technology has been tested.
