YB Series Prefabricated Transformer Substation

1. Definition

Full name: YB Series European-Style Prefabricated Transformer Substation.

Core Functions: Power receiving, voltage transformation, and distribution, providing 0.4 kV power for industrial, commercial, residential, and construction sites.

Compliance Standards: Complies with GB/T 17467-2010, IEC 60076, and IEC 62271.

Our European-style box transformer adopts a three-in-one (high-voltage cabinet + transformer + low-voltage cabinet) independent compartment design. It functions like a miniature distribution room, providing you with the highest level of safety protection and great maintenance flexibility. It is ideal for urban power grids, large factories, and new energy projects.

2. Structure & Standard Configuration

Three Independent Compartments: High-voltage room, Transformer room, and Low-voltage room.

Flexible Layouts: Corridor or non-corridor designs available to suit your space.

Customizable Materials: Choose from Aluminum-zinc coated steel, Stainless steel, or Color steel.

High-Performance Components:

•   HV: Load switch/ring main unit (with protection, metering, and communication).
•   Transformer: Oil-immersed or Dry-type (12/0.4kV, 50-1600kVA).
•   LV: Integrated incoming/outgoing circuits, compensation, metering, and protection.

3. Main Technical Parameters

We support full customization for enclosure materials, layout, and transformer capacity to meet your unique project requirements.

4. Why Choose Our YB Series?

🚀 Rapid Deployment: Factory-preinstalled. Just foundation & wiring required on-site, cutting your installation cycle by 70%+.

🛡️ All-Weather Reliability: Fully sealed, corrosion-resistant, and climate-adaptable (-30°C to +40°C).

⚙️ Intelligent O&M: Supports optional remote monitoring, fault auto-location, and "four-remote" functions.

💰 Cost-Effective: Lower total cost of ownership and less maintenance compared to traditional masonry substations.

5. Typical Application Scenarios

Urban: Residential districts, commercial centers, office buildings.

Industrial: Factories, mines, oilfields, and ports.

Special Projects: PV/Wind power grid connection, EV charging stations, and construction sites.

💡 Need a Tailored Design for Your Project?
