Global power infrastructure is undergoing a critical green transformation, driven by stricter carbon neutrality policies and environmental protection standards across Europe and developed regions. For decades, sf6 gas insulated switchgear has dominated high-reliability substation projects for its superior insulation and arc-extinguishing performance. However, SF6 is widely recognized as one of the most potent greenhouse gases, bringing long-term carbon emission pressure and environmental compliance risks for power operators. To address this industry pain point, we have upgraded our core medium-voltage switchgear solution by fully replacing traditional SF6-based structures with high-performance vacuum circuit breakers. This eco-friendly innovation has helped us obtain official recognition, with European customers listing our equipment as apreferred supplier to meet regional environmental regulations and sustainable grid requirements.
In medium-voltage power distribution scenarios covering industrial plants, commercial complexes and municipal grid networks, 10 kv switchgear and 11 kv switchboard are the most widely applied core equipment. Most conventional sf6 gas insulated switchgear in this voltage range relies on continuous SF6 gas sealing and regular leakage detection, which not only increases operational costs but also fails to comply with Europe's latest F-Gas regulations and carbon emission limits. As European authorities tighten restrictions on fluorinated greenhouse gas usage, power investors and EPC contractors are actively phasing out SF6-dependent equipment and seeking zero-emission, low-maintenance alternative solutions.
SF6 Gas Insulated Switchgear vs Vacuum-Based Air Insulated Switchgear
Traditional sf6 gas insulated switchgear gains advantages in compact footprint and strong environmental adaptability, which explains its long-term popularity in space-constrained substation designs. Nevertheless, its inherent environmental defects have become an irreversible disadvantage in the European market. SF6 gas leakage during installation, operation and maintenance will generate persistent greenhouse effects, making it difficult for projects to pass environmental audits and obtain green energy certification.
In contrast, our upgraded switchgear completely abandons SF6 insulation technology. Equipped with high-precision vacuum circuit breakers, the equipment uses atmospheric air for insulation and vacuum for arc extinction, achieving a true zero-greenhouse-gas operation. Whether applied in standard 10 kv switchgear power distribution systems or customized 11 kv switchboard industrial power supply projects, this vacuum-based design delivers identical or even better breaking performance and operational stability than traditional SF6 equipment.
Core Advantages of Vacuum Circuit Breaker Switchgear for European Projects
The full replacement of SF6 with vacuum circuit breakers brings dual value of environmental compliance and operational optimization, perfectly matching European market demands:
Strict Environmental Regulation Compliance: European power industries are accelerating the elimination of SF6 equipment to achieve regional carbon reduction targets. Our vacuum solution eliminates SF6 leakage risks entirely, helping grid operators and industrial clients avoid policy penalties and meet sustainable development assessment standards.
Lower Lifecycle Operational Cost: Traditional sf6 gas insulated switchgear requires regular gas pressure monitoring, leakage inspection and gas refilling throughout its service life. Our vacuum switchgear is maintenance-free in terms of gas management, greatly reducing daily operation workload and long-term after-sales costs for 10 kv switchgear and 11 kv switchboard applications.
Higher Operational Safety & Stability: Vacuum arc extinction features fast breaking speed, low partial discharge and strong anti-interference capability. Without gas aging and leakage failures, the equipment maintains stable performance in long-term grid operation, adapting to diverse working conditions of European municipal grids and industrial power distribution systems.
Simplified Installation & Upgrade: The modular vacuum switchgear retains flexible assembly characteristics, supporting convenient installation, expansion and later transformation. It can perfectly replace traditional SF6 equipment in existing substation renovation projects, with no need for large-scale civil engineering modifications.
