Product Introduction

  • The YB Series Multi-Functional Intelligent Prefabricated Substation is an integrated smart distribution device developed by our company according to market demand and relevant industry standards. This product integrates 10 kV high-voltage switchgear (with electric remote transmission and remote control capabilities), power transformers or special transformers, low-voltage intelligent switchgear, intelligent reactive power compensation systems, anti-theft metering systems, and emergency power supply systems into a complete distribution system according to user requirements.
  • The substation supports both local operation and remote control, enabling intelligent management such as remote control, measurement, signaling, and regulation, while also providing uninterrupted power supply. It is primarily used for receiving, distributing, and metering electrical energy in power distribution systems.
  • This product incorporates our company’s proprietary key technologies, optimizing the integration of three-phase emergency power systems, anti-theft metering boxes, multifunction intelligent meters, intelligent circuit breakers, static reactive power compensators, and energy-saving transformers. In the event of a substation fault, it provides emergency power for critical loads such as fire protection systems, hospitals, and elevators.
  • Through the intelligent control system, the substation achieves “Four Remote” management (remote measurement, signaling, control, and regulation), as well as remote monitoring, early warning, data collection, and energy usage analysis, further enhancing automation and intelligence levels.
  • The Multi-Functional Intelligent Prefabricated Substation not only meets the trends of land-saving, energy-saving, compact, small-sized, and unmanned operation, but also adapts to modern power systems’ requirements for informationization, networking, and intelligence, making it highly suitable for various applications.
