Daqo Debuts SF6-Free Switchgear and Modular Power Units in Munich

The centerpiece of the company's showcase is the DQS Air Series, a ring main unit (RMU) utilizing vacuum interruption and dry-air insulation. This configuration eliminates the use of sulfur hexafluoride, a potent greenhouse gas, while maintaining a compact footprint suitable for urban distribution and renewable energy sites. Complementing this is a new air-insulated RMU for secondary networks, which features remote monitoring capabilities to simplify infrastructure management.

To address the complexities of large-scale renewable projects, Daqo highlighted its containerized PV and BESS substation solutions. These units arrive pre-integrated with transformers and switchgear, a design choice intended to minimize onsite assembly and shorten the timeline between delivery and grid connection. For high-demand environments like data centers, the firm introduced DQMpower 2.0, a modular system that consolidates power quality management and distribution into a single, space-optimized package.

Kevin Lin, General Manager for Daqo’s Europe Region, noted that the current market environment demands cleaner hardware alongside greater delivery certainty. To support this, the company is leveraging its network of 32 manufacturing facilities to provide European partners with integrated technical packages, reducing the number of supplier interfaces required for complex electrical projects. Daqo is currently focusing on expanding its local coordination teams to solidify its role in the region's ongoing energy transition.
