  • YBT-10/0.4 Indoor Integrated Substation Features
  • #
    Efficient and Easy Installation
    The modular design allows for quick transport and assembly within a day. Factory-preinstalled components, including electrical testing and RTU configuration, minimize on-site work and downtime.
  • #
    Durability and Protection
    Built with a Siemens 8PT design, the substation uses high-quality galvanized steel for a compact and durable structure, offering an IP40 or higher protection rating. The base is hot-dip galvanized and powder-coated for added strength.
  • #
    Safety and Expandability
    The substation ensures safety with separate channels for high, medium, and low voltage circuits. It includes fire safety features like smoke sensors and optional fire suppression systems. The transformer section supports up to 100KVA for future expansion.
  • #
    Advanced Monitoring and Control
    The RTU system features a touchscreen interface that displays real-time system status, electrical parameters, and remote control capabilities for efficient monitoring and maintenance.
  • #
    Reliable Grounding and System Integrity
    Easy-to-connect grounding facilities with copper busbars ensure electrical continuity and safe operation for reliable system performance.
