Description

Overview

As a professional manufacturer of fully sealed oil immersed power transformer, our S13M series products deliver exceptional versatility and reliability for diverse power distribution scenarios. These transformers are widely deployed in high-traffic and high-demand environments, including high-rise buildings, bustling commercial centers, subway systems, busy airports, and key transportation hubs, where stable power supply is critical for daily operations. They also serve as a robust power solution for industrial facilities, rugged mining enterprises, offshore drilling platforms, and oil extraction platforms—settings that demand equipment capable of withstanding harsh working conditions.
What sets the S13M series apart is its outstanding suitability for fire-sensitive locations with stringent safety requirements, such as flammable and explosive areas, where its fully sealed structure eliminates oil leakage risks and minimizes fire hazards. Beyond industrial and commercial applications, these transformers are equally well-suited for residential communities, commercial streets, and rural areas, effectively supporting both power supply for industrial machinery and daily lighting needs, ensuring consistent performance across urban and rural power grids.
Key Features
  • Zero-Leakage Sealed Structure：Full-seal tank design eliminates oil leakage and evaporation, adapts to harsh outdoor/indoor environments, and reduces maintenance frequency.
