Amid the drive for green and smart power grid construction, Juhonkia delivers remarkable achievements backed by solid technological expertise and persistent innovation. Recently, two core products, GSR-40.5-1250-31.5kA and GSR-40.5-2500-31.5kA eco-friendly gas-insulated metal-enclosed switchgear, have successfully passed all type tests and obtained official certification issued by TUV Rheinland Germany. This fully validates the company’s technological strength, product quality and manufacturing capacity in the field of medium-voltage eco-friendly switchgear on the international authoritative stage.
Leading Technology, Empowering Green Power Grid
The certified products adopt dry and clean air as insulating medium, completely eliminating traditional sulfur hexafluoride (SF6) gas with zero global warming potential (GWP). They achieve low-carbon or even zero carbon emissions throughout the whole service life, conforming to national dual-carbon strategy and green power grid development orientation.
Authoritative Testing, Reliable Quality & Safety
The product is designed and tested in strict accordance with the latest standards of the International Electrotechnical Commission (IEC). Certification criteria include IEC 62271-200:2021+A1, IEC 62271-100:2021+A1 and IEC 62271-102:2018+A1. Test reports show that the product achieves outstanding performance in core indicators such as dielectric properties, temperature rise characteristics, short-circuit breaking and making capacity. Key performance parameters are as follows:
| Item | Value | Item | Value |
|---|---|---|---|
| Rated Voltage | 40.5 kV | Frequency | 50 Hz |
| Rated Current of Circuit Breaker | 1250A / 2500A | Power Frequency Withstand Voltage | 95 / 118 kV |
| Rated Short-time Withstand Current | 31.5 kA (4s) | Lightning Impulse Withstand Voltage | 185 / 215 kV |
| Rated Peak Withstand Current | 80 kA | Temperature Rise Test Condition | 1.1 × Rated Current |
These solid figures fully verify the safety and reliability of the product under high voltage and heavy current operating conditions.
Professional Recognition, Unlocking the Global Market
As a globally recognized testing and certification body, TUV Rheinland Germany’s certifications enjoy high credibility worldwide, especially in European, Middle Eastern, African and Asia-Pacific markets. The successful certification marks that Juhonkia’s eco-friendly gas-insulated switchgear not only meets Chinese standards, but also gains recognition from top-tier international standards, further enhancing the core competitiveness of the product in both domestic and overseas markets.
As the global energy structure speeds up the shift towards clean and low-carbon development, the power sector sees growing demand for eco-friendly, efficient and intelligent switchgear.
Juhonkia Electric consistently pursues green intelligent manufacturing and technological innovation simultaneously. Multiple products of the company have obtained carbon footprint certification and TUV Rheinland international certification. Going forward, we will further delve into eco-friendly intelligent electrical equipment, launch safer, greener and more reliable products, and contribute to global energy transition and the construction of new power systems.
