YB Series European-Type Prefabricated Substation – 12kV Outdoor Compact Transformer Box Substation for Residential and Industrial Power Distribution

YB Series European-Type Prefabricated Substation (12kV Compact Box Transformer)

Product Overview

The YB series is a high-performance European-type prefabricated substation designed for 12kV (10kV) three-phase AC power systems. This compact, outdoor solution integrates high-voltage switchgear, a power transformer, and low-voltage distribution devices into a single, factory-assembled, weather-resistant enclosure. It is engineered to provide a safe, reliable, and space-saving power conversion solution for modern urban and industrial infrastructure.

Core Features & Technical Advantages

• Integrated 3-Compartment Design: Features independent, factory-separated compartments for the High-Voltage Room, Transformer Room (变压器室), and Low-Voltage Room to ensure operational safety.

• All-Weather Outdoor Protection: Built with a durable, anti-corrosive industrial green shell and a sloped roof design to effectively prevent rain accumulation and environmental wear.

• Efficient Thermal Management: Equipped with multiple built-in ventilation louvers on the access doors to facilitate natural air convection, maintaining optimal temperatures for the internal transformer.

• Enhanced Public Safety: Each functional compartment is fitted with prominent yellow triangular “High Voltage Danger” (高压危险) warning signs to prevent unauthorized access.

• Space-Saving Aesthetic: The compact “box-type” structure requires significantly less land than traditional substations and is designed to blend seamlessly into residential green belts and urban landscapes.

• Standardized 12kV Reliability: Optimized for stable power conversion from 10kV or 12kV utility grids to standard user-level voltages (380V/220V).
