Description
315kVA European Box Type Substation is designed for medium-capacity power distribution projects that require a compact layout, integrated protection, and reliable outdoor performance.
This prefabricated substation integrates transformer, medium-voltage switchgear, low-voltage distribution, and protection systems into a single enclosure. It is widely used in industrial parks, renewable energy projects, urban distribution networks, and utility applications.
As a manufacturer, we support customized configurations based on voltage level, installation environment, and project requirements.
315kVA European Box Type Substation Overview

This powerful primary image showcases the fully assembled 315KVA European Box Type Substation, immediately establishing its professional profile and robust build quality. The photograph captures the unit’s comprehensive exterior, emphasizing its compact, space-saving footprint that is ideal for both urban and industrial settings where real estate is at a premium.
The clean, modern lines of the galvanized steel or high-quality stainless-steel enclosure are highlighted, reflecting a design that is not only aesthetically pleasing but also engineered for long-term durability. Key external features such as the secure, lockable doors, robust ventilation louvres designed to be weatherproof, and integrated lifting points are visible, providing a first impression of a product that is ready for easy installation, reliable operation, and minimal maintenance in demanding environments.
Integrated Structure and System Configuration

This detailed collage offers a critical look inside the 315KVA European Box Type Substation, breaking down its sophisticated internal architecture. It vividly illustrates the three distinct, segregated chambers: the High Voltage Chamber, designed with safety in mind for secure cable connections and featuring advanced switchgear; the core Transformer Chamber, housing the high-efficiency, 315KVA-rated transformer that is the heart of the unit, optimized for minimal energy loss; and the Low Voltage Chamber, where power is distributed via customizable panels.
The final quadrant prominently displays the High-Quality Copper Bars, underscoring a commitment to superior conductivity and efficiency. These bars, with their excellent load-bearing capacity and corrosion resistance, ensure stable performance, reduce overheating risks, and contribute directly to the substation’s overall energy efficiency and long-term operational economy.

315kVA Substation Project Applications

This 315kVA European box type substation is commonly used in medium-capacity distribution projects where space efficiency, safety, and integrated design are required. We design and manufacture the substation in accordance with IEC standards for prefabricated substations, and adapt configurations to meet local utility or project specifications.
Typical applications include industrial parks, renewable energy plants, commercial developments, and urban distribution networks. The compact enclosure allows flexible installation in limited spaces while maintaining clear functional separation between transformer, MV, and LV compartments.
For EPC and utility projects, we support configuration adjustments based on site conditions, voltage levels, and protection schemes. This flexibility helps engineers align the substation design with local standards, project specifications, and operational requirements.
Our engineering team works closely with clients during the design and procurement stages to ensure smooth integration into overall power distribution systems.
