Oil-filled transformer / Molded transformer: High-efficiency, energy-saving transformers that support the safe operation of railways.
In the railway industry, a safe and stable power supply is the foundation of safe operations. In particular, transformers play an essential role in stabilizing power, and their reliability and efficiency are directly linked to the safety of operations. Reducing power loss and promoting energy efficiency contribute not only to lowering operational costs but also to reducing environmental impact. The 2026 Top Runner transformer supports the improvement of reliability and sustainability of railway infrastructure through its high efficiency and energy-saving performance that comply with Top Runner standards. We will handle everything from proposals to installation work (equipment updates). 【Usage Scenarios】 - Substation equipment within stations - Power supply to signaling equipment - Power supply for maintenance and servicing - Power supply to tunnel equipment 【Effects of Implementation】 - Energy savings through reduced power loss - Maintenance of safe operations through stable power supply - Reduction of operational costs - Reduction of environmental impact Sanmei Co., Ltd. is an authorized distributor (trading company/system integrator) of Daihen Co., Ltd.
