Our switchgear is not only suitable for our GSM series AIS RMU, but it can also seamlessly fit into all kinds of similar switchgears, ensuring compatibility and flexibility for your specific requirements.
Experience the convenience and efficiency of our product. Choose GRENO (XIAMEN) SWITCHGEAR CO., LTD. for professional service and a win-win business partnership.
Introducing the latest innovation from GRENO (XIAMEN) SWITCHGEAR CO., LTD., our high-performance switchgear with enhanced insulation abilities for arc-extinguishing, our switchgear ensures optimum safety when in open status, thanks to the filling of SF6 gas at a pressure of 0.03Mpa~0.04Mpa.
Not only does our switchgear provide superior safety, but it also offers a compact design for added convenience. We have successfully reduced the overall size without compromising on performance, making it easier to install and use.
The copper contactor used in our switchgear is made from the finest material available. With more than 99.95% Cu content, our contactor guarantees exceptional abrasion rigidity. Our special production process ensures the highest quality and durability. We proudly call this material T2 copper.
In addition, our switchgear features an increased phased distance of 210mm. Our unique design extends the air and creepage distance, further enhancing safety and reliability.
Experience the excellence of GRENO (XIAMEN) SWITCHGEAR CO., LTD. with our cutting-edge switchgear that combines advanced insulation abilities, compact size, and top-quality materials. Upgrade your electrical system today for enhanced performance and peace of mind.
5) We strictly control the quality of our products by choosing the best quality epoxy resin, even though it may be expensive. Before every production, we conduct a belt transect test using epoxy resin to ensure its quality. According to the test data, the major material quality, such as bending strength, tensile strength, and impact strength, is well controlled.
6) Our internal contact terminals are made of permanent magnetism material. When the LBS switches to the open position, the arc naturally becomes thinner and thinner, leading to its self-extinguishment in SF6 gas.
Feel free to send us any enquiries anytime. We warmly welcome your inquiries.
