Domestic Enclosed Busway Manufacturers Accelerate IP66+ Anti-Salt Spray Production Lines to Meet New Environmental Requirements for Offshore PV Booster Stations in Middle East and Southeast Asia

Introduction

As of April 1, 2026, multiple enclosed busway manufacturers in Qinghai and Jiangsu provinces are upgrading production lines to achieve IP66 protection standards and integrate anti-salt spray coatings. This initiative responds to the stringent environmental adaptability requirements for offshore photovoltaic (PV) booster station projects in high-humidity, high-salt, and strong-UV regions such as the UAE, Saudi Arabia, and Vietnam. The upgrades have already secured small-batch trial orders from Middle Eastern clients for three manufacturers. This development is critical for the power equipment and renewable energy sectors, as it highlights the growing demand for durable infrastructure in harsh marine environments.

Event Overview

According to disclosed information, domestic enclosed busway manufacturers are actively enhancing their production capabilities to meet IP66+ and anti-salt spray specifications. These upgrades are driven by the operational demands of offshore PV projects in the Middle East and Southeast Asia, where equipment must withstand extreme conditions. The initial phase has seen three manufacturers secure trial orders, signaling market validation for these technical improvements.

Impact on Sub-Sectors

Direct Export Enterprises

Manufacturers specializing in enclosed busways for international markets are directly affected. The need for IP66+ and anti-salt spray features necessitates production line upgrades, which may increase short-term costs but enhance long-term competitiveness in high-value markets.

Raw Material Suppliers

Suppliers of corrosion-resistant coatings and high-durability materials will experience heightened demand. Companies providing these inputs should prepare for increased orders and potential shifts in material specifications.

Engineering and Construction Firms

Firms involved in offshore PV projects must now account for the enhanced specifications of enclosed busways in their designs and procurement processes. This could lead to adjustments in project timelines and budgets.

Key Focus Areas and Recommended Actions

Monitor Regional Project Pipelines

Companies should track upcoming offshore PV projects in the Middle East and Southeast Asia to anticipate demand spikes for IP66+ compliant equipment.

Assess Supply Chain Readiness

Manufacturers must evaluate their supply chains to ensure timely access to specialized materials like anti-salt spray coatings and UV-resistant components.

Engage in Early Client Consultations

Proactive engagement with project developers and EPC contractors can help manufacturers align their upgrades with specific project requirements, reducing time-to-market for new product variants.

Editorial Perspective

From an industry standpoint, this development signals a broader shift toward higher environmental resilience in power infrastructure for renewable energy projects. While the initial orders are small, they represent a tangible market response to technical upgrades. The trend is likely to accelerate as more regions adopt similar standards for offshore installations.

Conclusion

The move by domestic manufacturers to upgrade enclosed busway production lines underscores the increasing importance of environmental adaptability in global renewable energy projects. For now, this should be viewed as an emerging trend with significant growth potential, particularly in markets with demanding operational conditions.
