The South Korea ACSR Cable market size was valued at USD 218.1 million in 2024 and is projected to reach USD 285.4 million by 2030, at a CAGR of 4.6% during the forecast period 2024‑2030.
ACSR cables, or Aluminum Conductor Steel Reinforced cables, are essential components in electrical power transmission and distribution systems. These cables consist of a core of steel strands surrounded by layers of aluminum conductors, providing both mechanical strength and high electrical conductivity. They are widely used in overhead lines due to their durability, cost‑effectiveness, and ability to withstand environmental stresses, making them ideal for long‑distance power delivery in urban and rural settings alike.
The market is driven by rising electricity demand in South Korea, coupled with ongoing grid modernization efforts to enhance reliability and efficiency. Furthermore, investments in renewable energy integration are boosting the need for robust transmission infrastructure. Key players such as LS Cable & System, Taihan Electric Wire Co. Ltd., and Nexans Korea are leading innovations in high‑performance ACSR variants. For instance, recent advancements focus on improved thermal resistance to support higher load capacities, further propelling market growth amid the country’s push for sustainable energy solutions.
