Product Details of YBW Outdoor Prefabricated Substation

1. Product Introduction

YBW series outdoor prefabricated substation (European-style) is designed and manufactured in compliance with GB/T 17467-2018 and IEC 62271-200. It is a compact, integrated power distribution package, positioned to replace traditional civil substations with fast deployment, high efficiency, safety, reliability and cost savings.

It integrates high-voltage switchgear, distribution transformer, low-voltage switchgear, metering, reactive power compensation, intelligent monitoring, lightning protection and moisture-proof systems. All assembly, wiring, testing and commissioning are completed in the factory. On site, only foundation fixing, cable connection and grounding are needed, greatly shortening construction period and cost.

The fully sealed and anti-corrosion enclosure enables stable operation in harsh outdoor environments: high temperature, cold, humidity, dust and coastal salt fog. The substation supports flexible customization for voltage, capacity, protection grade and power supply mode (terminal, ring main, dual-power).

An intelligent monitoring system is optional for real-time status monitoring, fault alarm and remote operation, realizing unattended operation and intelligent management.

3. Main Features

1. High integration & factory prefabrication

   All components are assembled and tested in the factory. On-site installation only takes 7–15 days, reducing construction period by over 70%.

2. Compact structure & small footprint

   Covers only 1/5 to 1/10 the area of traditional substations. Flexible installation near load centers, saving cables and cost.

3. Outdoor all-weather protection

   Rainproof, dustproof, anti-corrosion, UV-resistant. Suitable for humid, dusty, coastal and harsh environments.

4. Safe, reliable & easy maintenance

   Complete protection: overcurrent, short-circuit, overload, temperature, lightning. Long maintenance-free period. Intelligent monitoring supports unattended operation.

5. Highly customizable

   Customizable transformer, voltage, capacity, protection grade, enclosure material, power supply scheme and appearance.

6. Energy-saving & eco-friendly

   Equipped with high-efficiency energy-saving transformers. Low loss, low noise, environmentally friendly, in line with national energy-saving policies.
