Application and Environmental Conditions
The European Outdoor Prefabricated Substation is designed to function efficiently in diverse environments. It operates under the following conditions:
- Altitude: Suitable for installation at locations up to 2000 meters above sea level.
- Temperature Range: Operates effectively within a temperature range of -25°C to +40°C.
- Humidity Tolerance: At 25°C, the daily average relative humidity does not exceed 95%, and the monthly average does not exceed 90%.
- Installation Requirements: The substation should be installed in areas free from fire hazards, explosion risks, conductive dust, corrosive chemical gases, and severe vibrations. If the conditions exceed these limits, customization options can be discussed.

Key Features and Advantages
Comprehensive and Compact Design
The European Outdoor Prefabricated Substation integrates high-voltage switchgear, distribution transformers, low-voltage switchgear, power metering equipment, and reactive power compensation devices into a single unit. This all-in-one design ensures seamless power distribution and efficient space utilization.

Enhanced Safety and Protection
Equipped with advanced high and low-voltage protection mechanisms, the European Outdoor Prefabricated Substation offers reliable operation and easy maintenance. It ensures a high level of electrical safety, reducing risks associated with electrical failures.

Flexible Wiring Configurations
The European Outdoor Prefabricated Substation supports various wiring schemes, allowing customization according to specific power distribution requirements. This flexibility enhances its adaptability to different project needs.

Multiple Model Options
Available in various designs such as standard, villa-type, and compact configurations, the European Outdoor Prefabricated Substation caters to different aesthetic and functional needs. This variety makes it suitable for both residential and industrial applications.

Intelligent Power Distribution Capabilities
The high-voltage ring main unit can integrate an automation terminal (FTU) for reliable fault detection, including short-circuit and single-phase ground fault detection. It also supports remote monitoring and control, facilitating smart grid upgrades and automated power management.

Transformer Options
The European Outdoor Prefabricated Substation is compatible with energy-efficient transformers, including low-loss, oil-immersed, and fully sealed models from the S9, S10, and S11 series. Additionally, eco-friendly options such as resin-insulated or NOMEX paper-insulated dry-type transformers are available to meet various environmental and operational needs.

High-Voltage Protection
The high-voltage side of the European Outdoor Prefabricated Substation typically employs a combination of load switches and high-voltage fuses for comprehensive protection. The fuses are designed for high-breaking capacity and feature an impact mechanism for reliable operation. For substations exceeding 800kVA, vacuum circuit breakers such as ZN28 and VS1 can be used for enhanced protection.

Low-Voltage Distribution and Compensation
On the low-voltage side, the main circuit breaker is either a universal or intelligent circuit breaker, ensuring selective protection. The outgoing circuit breakers utilize modern molded-case circuit breakers that are compact and arc-resistant, with configurations supporting up to 30 circuits.

The European Outdoor Prefabricated Substation is a cutting-edge power distribution solution designed for reliability, safety, and efficiency. Its modular and compact design, combined with flexible configuration options, makes it an good performance choice for a wide range of applications.
