At Jihui Electric Group Co., Ltd., we focus on providing safe, stable, and efficient power distribution solutions for customers around the world. As a professional manufacturer of medium and low voltage electrical equipment up to 35kV, we design and produce a wide range of products, including outdoor prefabricated substations, ring main units, Cable distribution boxes, combination transformers, SF6 load switches, and Vacuum circuit breakers.

Our Outdoor prefabricated substation (European style) is developed for modern power distribution systems that require compact structure, reliable operation, easy installation, and long service life. By integrating transformers, medium voltage switchgear, and low voltage distribution equipment into one complete unit, this solution helps customers reduce installation time and improve project efficiency.

From urban power networks to renewable energy projects, industrial plants, commercial buildings, and infrastructure construction, our European Style Prefabricated Substations provide flexible power solutions for different application environments.

What Is an Outdoor Prefabricated Substation (European Style)?

An outdoor prefabricated substation (European style) is a complete electrical power distribution unit that combines a transformer, medium voltage switchgear, low voltage switchgear, and related protection devices inside a prefabricated enclosure.

Unlike traditional substations that require customers to build separate rooms and install equipment step by step, our prefabricated substation is manufactured, assembled, and tested in our factory before delivery. After arriving at the project site, customers only need to complete basic installation and cable connection.

This design saves construction time, reduces engineering costs, and improves the overall reliability of the power distribution system.

The European style design focuses on safety, appearance, environmental adaptability, and convenient maintenance. The compact enclosure structure allows the equipment to be installed in areas where space is limited while maintaining excellent electrical performance.

How Does Our European Style Prefabricated Substation Work?

The working process of our outdoor prefabricated substation is simple. The medium voltage power source first enters the substation through the medium voltage switchgear. The switchgear controls and protects the incoming power supply.

The transformer inside the substation then reduces the voltage to a suitable level required by end users. After voltage conversion, the low voltage switchgear distributes electricity to different loads, such as factories, buildings, charging stations, and other electrical equipment.
