This is a specific factor that can propel the growth of the Asia Pacific Conventional Overhead Conductor Market in the coming years. For example, in Hanoi, Vietnam, the Hanoi Power Company uses XLPE cables in the city center but switches to ACSR for radial feeders extending into outlying communes, reducing project costs by 40% as reported by the Vietnam Electricity Group. Similarly, in Jakarta, PLN’s suburban expansion program relies on AAAC conductors for 30 kV feeders serving new housing developments.

Adoption in Temporary and Emergency Power Infrastructure

The rapid adoption of the temporary and emergency power networks due to their rapid deploy ability, ease of repair, and compatibility with modular support structures is additionally to enhance the growth of the Asia Pacific Conventional Overhead Conductor Market. As per the International Federation of Red Cross and Red Crescent Societies, over 75% of post-disaster electrification efforts in the Asia Pacific between 2018 and 2023 utilized ACSR conductors for restoring power after cyclones, floods, and earthquakes.

MARKET CHALLENGES

Increasing Regulatory Pressure to Reduce Line Losses and Improve Efficiency

The regulatory mandates aimed at minimizing technical losses in power transmission and distribution networks are challenging the growth of the Asia Pacific Conventional Overhead Conductor Market. As per the International Energy Agency, the average technical loss in transmission and distribution networks across the Asia Pacific stands at 9.3%, significantly above the global benchmark of 6.5%. Countries like India and Thailand have set national targets to reduce losses to below 6% by 2027, prompting utilities to reassess conductor selection. The Central Electricity Authority of India reports that ACSR conductors contribute to 18–22% of total resistive losses in 33 kV and 66 kV circuits due to their lower conductivity-to-weight ratio. Moreover, Thailand’s Energy Regulatory Commission has linked utility performance incentives to loss reduction, which is accelerating the shift away from standard conductors.

Right-of-Way Constraints and Land Acquisition Delays

The shrinking availability of right-of-way (ROW) and prolonged land acquisition processes in densely populated areas is also to hamper the growth of the Asia Pacific Conventional Overhead Conductor Market in the coming years. According to the United Nations Human Settlements Programme, urban sprawl has reduced available open land, forcing utilities to reroute lines or adopt alternative technologies. In response, Thailand’s Electricity Generating Authority has shifted to HTLS conductors in 60% of new inter-provincial lines to minimize land use. The World Bank notes that conventional conductor projects face 2.5 times more litigation than underground or compact HTLS alternatives.
