Description
Le 35KV European Box Substation is a prefabricated compact substation designed for medium voltage power distribution systems. It integrates transformers, medium voltage switchgear, protection devices, and auxiliary equipment into a single enclosure, reducing on-site construction work and installation time.
This solution is widely used by utilities, industrial facilities, and EPC contractors who need a safe, stable, and easy-to-deploy substation. With its European-style box structure, the system supports outdoor installation, flexible configuration, and long-term operation in various grid and environmental conditions.
Product Overview: 35kV European Box Type Substation

This 35KV European Box Type Substation is designed as a complete box-type power distribution system for medium and high voltage applications.
It integrates MV & HV transformers, switchgear, protection devices, and auxiliary systems into one compact enclosure.
The box-type design allows users to build, expand, and upgrade power distribution systems quickly, especially in projects with limited construction time or restricted site conditions. By integrating medium-voltage switchgear, transformers, and low-voltage distribution equipment into one prefabricated enclosure, the 35KV European Box Type Substation reduces on-site installation work and shortens commissioning schedules.
When load demand increases, users expand the system in a predictable and controlled manner by upgrading transformer capacity or adding feeder units. This flexible configuration supports long-term development plans and helps project owners avoid early system replacement.
The system delivers safe and reliable operation with stable electrical performance during continuous service. Engineers design the enclosure, insulation coordination, and internal layout to support long service life, reduce operational risk, and protect operating personnel.
Customers commonly choose this prefabricated box type substation when they need:
Medium-voltage power supply for factories, industrial parks, and manufacturing facilities, where stable power and minimal downtime directly affect productivity
Grid connection solutions for renewable energy projects, including solar power plants and wind farms that require reliable step-up or step-down substations
Compact substations for urban or space-limited sites, such as commercial developments, infrastructure projects, and public utilities
The system offers simple operation and low maintenance requirements, which helps utility companies and EPC contractors control lifecycle costs and improve operational safety. Project owners also benefit from the prefabricated design, which improves delivery certainty, reduces construction risk, and simplifies project coordination.
Internal Configuration of the 35kV Compact Substation System

This image shows the internal layout of the 35KV compact substation system, where engineers arrange all major electrical components in separated, clearly defined compartments. This layout improves operational safety, simplifies inspection, and helps maintenance teams identify equipment quickly during routine checks or fault handling.
The design physically separates medium-voltage, transformer, and low-voltage sections. This separation reduces the risk of electrical interference, enhances insulation coordination, and supports stable long-term operation under continuous load conditions.
The system supports multiple configuration options, including:
Medium-voltage switchgear for incoming and outgoing feeders, allowing flexible grid connection and feeder management
Oil immersed transformers for high-capacity applications and outdoor installations, where strong thermal performance and overload capability are required
Dry type transformers for projects that prioritize low fire risk, reduced oil use, and indoor-friendly operation, such as commercial or densely populated sites
Customers often search for a substation solution that allows flexible transformer selection without redesigning the entire system. This internal layout supports that requirement by accommodating different transformer types and ratings within a standardized enclosure.
Engineers commonly apply this design in industrial production lines, renewable energy power plants, and medium-voltage distribution substations, where safety, reliability, and ease of maintenance directly affect operating costs and system uptime. By combining modular configuration with clear internal zoning, the substation helps project owners balance performance, safety, and long-term operational efficiency.
Typical Internal Configuration Options
| Component Type | Common Selection Reason | Application Scenario |
|---|---|---|
| MV Switchgear | Reliable protection and switching | Utility grids, industrial feeders |
| Transformateur immergé d'huile | High efficiency and strong overload capacity | Outdoor substations, heavy industry |
| Dry Type Transformer | Low fire risk, low noise | Commercial zones, renewable projects |
This modular internal arrangement improves maintenance access and reduces downtime during inspections.
Structural Design of the 35KV European Box Substation

The structural design of the 35KV European Box Type Substation prioritizes durability and outdoor adaptability for long-term field operation. Engineers reinforce the housetop, integrate ventilation blinds, install certified lifting rings, and design a rigid under-frame beam channel to withstand transportation stress, outdoor exposure, and repeated lifting during installation.
The system uses a concrete foundation combined with ventilated brick walls to improve airflow and maintain thermal stability around key electrical components. This structural approach reduces internal heat accumulation and helps the substation operate reliably under continuous load and varying ambient temperatures.
External measuring pockets and full-access doors allow technicians to perform inspection, monitoring, and routine operation without dismantling major structural elements. This feature shortens maintenance time, improves operator safety, and minimizes service interruptions during the substation’s lifecycle.
This structural configuration particularly suits customers who:
Install substations in outdoor or semi-outdoor environments, such as industrial zones and utility networks
Require fast civil works through prefabricated solutions, especially in EPC or fast-track projects
Operate equipment in harsh climates, including high temperatures, humidity, dust, or remote locations
The prefabricated structure reduces on-site construction time, lowers installation risk, and improves overall project delivery efficiency, making it a practical choice for utilities, industrial users, and infrastructure developers seeking reliable medium-voltage substation solutions.
