YB Series Outdoor Prefabricated Substation (Compact Transformer Station)

Product Overview

The YB Series is a high-performance, compact outdoor power distribution solution that integrates high-voltage switchgear, transformers, and low-voltage distribution devices into a single, factory-preassembled enclosure. This “all-in-one” station is designed for 12kV power systems, offering a modular and mobile alternative to traditional civil engineering substations. It is the ideal choice for urban power grid modernization, residential complexes, industrial parks, and construction sites where space is limited and rapid deployment is required.

Core Features & Technical Advantages

• Integrated RMU Control: The high-voltage compartment features multiple XGN15-12 Ring Main Unit (RMU) modules for reliable load control and circuit protection.

• Smart Grid Automation: Equipped with a DTU-100 station terminal for real-time data acquisition, remote monitoring, and rapid fault location.

• Robust All-Weather Protection: The cabinet is constructed from high-quality steel with a specialized industrial coating, providing anti-corrosion, anti-rust, fireproof, and heat-insulating properties for outdoor use.

• Ultra-Compact Footprint: Occupies only about 1/10th the space of a traditional substation, significantly reducing land acquisition costs and installation time.

• Advanced Monitoring Interface: Includes clear circuit mimic diagrams, status indicators, and digital meters to allow technicians to track system health at a glance.

• Enhanced Safety Design: Features integrated pressure relief vents and a secure double-door locking system to ensure personnel safety and prevent unauthorized access.
