As Europe continues to expand renewable energy capacity, energy storage systems, and electrification initiatives, project developers are under increasing pressure to accelerate grid connections for new generation assets and high-demand electrical loads. At the same time, they must comply with more stringent expectations around environmental sustainability, system reliability, and project execution.

One of the key highlights presented by Daqo was its DQS Air Series SF6-free Ring Main Unit (RMU). Utilizing dry-air insulation combined with vacuum interruption technology, the DQS Air series offers an environmentally responsible alternative to traditional SF6-based medium-voltage equipment. Its compact, sealed construction is designed to minimize maintenance requirements while delivering dependable performance across urban power distribution networks, renewable energy interconnections, industrial installations, and grid modernization projects.

Daqo also unveiled its latest generation of SF6-free air-insulated RMUs developed specifically for secondary distribution applications. Featuring flexible configuration options, intelligent monitoring capabilities, and remote operation readiness, these solutions address the growing demand for sustainable, efficient, and easily manageable power distribution systems.

For renewable energy generation and battery storage applications, Daqo showcased its integrated containerized PV and BESS substation solutions. By factory-integrating step-up transformers, medium-voltage and low-voltage switchgear, monitoring systems, and auxiliary equipment into a single modular unit, the company enables developers and EPC contractors to reduce on-site complexity, streamline project coordination, and accelerate grid connection timelines.

To address the needs of energy-intensive industries such as data centers, Daqo introduced DQMpower 2.0, a modular power infrastructure platform combining low-voltage distribution, UPS functionality, power quality management, and advanced monitoring systems. This integrated approach enhances deployment speed, optimizes the use of electrical room space, and provides greater operational transparency. The company's solid-state transformer technology also attracted considerable attention as a future-ready solution supporting dynamic interaction among power grids, loads, energy storage systems, and DC networks.

"Our conversations with customers at The smarter E Europe reinforced a clear market trend: infrastructure projects increasingly require environmentally sustainable technologies, faster grid integration, and greater confidence in project delivery," said Kevin Lin, General Manager for Daqo's Europe Region. "To meet these expectations, Daqo is expanding its European coordination capabilities and strengthening its partner ecosystem to provide customers with integrated technical solutions, simplified interfaces, and enhanced delivery support."

Daqo's strategy in Europe focuses on combining large-scale manufacturing capabilities with strong local coordination and partner engagement. The company's manufacturing network comprises 32 production facilities with expertise spanning medium- and low-voltage equipment, transformers, automation technologies, and system integration.

This approach enables European customers to benefit from consolidated technical solutions, reduced supplier complexity, and improved project execution control. Moving forward, Daqo intends to deepen its collaboration with utilities, project developers, EPC firms, and industrial customers to support the development of cleaner, more reliable, and rapidly deployable energy infrastructure throughout Europe.

High Voltage Current Sensor Market Overview

Key Market Insights
High-voltage current sensors are specialized devices used to measure and monitor electrical current in high-voltage environments while maintaining electrical isolation and operational safety. These sensors are commonly deployed in electric vehicles (EVs), battery management systems, traction inverters, EV charging stations, renewable energy installations, and industrial power systems. Technologies such as Hall-effect sensing, shunt-based sensing, fluxgate, and magnetoresistive methods are widely used to enable accurate current detection, often without direct electrical contact.

These sensors support essential functions including real-time current monitoring, fault identification, power management, and equipment protection. As industries increasingly adopt high-voltage electrical architectures, the demand for reliable and efficient current-sensing solutions continues to rise.

Market Drivers
The high-voltage current sensor market is expanding globally due to the accelerating transition toward electrification in transportation, renewable energy, and industrial applications.
