product list
The SRM series Gas insulated switchgear was passed the type test from National High-low Voltage Electrical Apparatus Quality Supervision and Inspection Center (NEIC). The product widely use for 10kV, 24kV Power Systems. The SRM switchgear was designed for modular usage, it can make difference group, that can suitable for lots of requirements of compact area. SRM series switch is complete sealed system, all the electric parts and switch were sealed inside the stainless cabinet. The switch equipment will not affect by surround environment, which can make sure work safety and free maintains. And the end-user can choose the extension busbar to make it complete modular design. Meanwhile, we supply the automation and intelligentialize program, that can low down the work for workers.
