Policy-Driven Transformation: Eco-Friendly Solutions Take Center Stage

With the implementation of the EU’s new F-Gas Regulation (Regulation (EU) 2024/573), the power equipment industry is entering a countdown toward environmental transformation. The regulation explicitly prohibits, starting in 2026, the use of fluorinated greenhouse gases in medium-voltage switchgear rated at 24 kV and below. This restriction will be extended to equipment up to 52 kV from 2030 onward, accelerating the industry’s shift away from sulfur hexafluoride (SF₆)—a gas with a high global warming potential.

ROCKWILL has launched a highly competitive eco-friendly switchgear solution: the QGG Series Solid Insulated Switchgear. Integrating decades of product development expertise from both Air-Insulated Switchgear (AIS) and Gas-Insulated Switchgear (GIS), the QGG series represents a major breakthrough in medium-voltage technology, offering exceptional operational safety. As a core component of power distribution networks, it is widely deployed across various distribution systems.

The QGG series utilizes vacuum interrupters for arc quenching, and all high-voltage live parts are fully encapsulated using solid insulating materials—specifically epoxy resin—with superior dielectric performance. This design eliminates the need for a pressurized gas chamber (previously operating at 0.03 MPa), achieving true full insulation, complete sealing, and maintenance-free operation.

Equipped with an intelligent online monitoring system, the QGG series enables real-time monitoring of critical internal components, continuously collects operational parameters, and automatically assesses potential fault risks—providing robust protection for both the switchgear itself and the entire distribution line.

After years of dedicated R&D, ROCKWILL’s solid insulated switchgear has evolved into four distinct product series (IV Series), each tailored with unique features to meet diverse application requirements.
