Zhejiang Jiangshan Hengli Electrical Co., Ltd. is one of the leading manufacturers and suppliers of 500 kva mini substation in China. If you're going to wholesale durable 500 kva mini substation made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
The compact substation integrates the main electrical equipment into a factory-assembled enclosure, typically including medium-voltage switchgear, a 500kVA transformer, low-voltage distribution equipment and necessary protection or monitoring components. Depending on the project, the transformer can be oil-immersed or dry type, while the enclosure and internal configuration can be customized to suit different installation environments.
For overseas EPC contractors, electrical distributors and industrial users, this integrated design can simplify transportation, site installation and commissioning.

Compact Construction for Faster Project Installation
A 500kVA Mini Substation generally combines three functional sections: medium-voltage incoming equipment, the power transformer and low-voltage distribution equipment. The MV section receives power from the utility or local distribution network, while the transformer steps the voltage down to the required LV level.
The LV section distributes power to downstream loads through circuit breakers, busbars and outgoing feeders. Protective devices, metering, temperature monitoring and other accessories can be incorporated according to the project specification.
The enclosure separates the electrical sections and provides protection against weather, dust and unauthorized access.
Key Features & Advantages
Compact footprint
The integrated structure reduces the space required for a separate transformer room and switchgear installation, making it suitable for sites where available land is limited.
01
Factory-assembled design
Major components can be assembled and tested before shipment. This helps reduce the amount of electrical installation work required at the project site.
02
Flexible configuration
Zhejiang Hengli Electrical can customize HV/LV voltage, transformer type, cooling method, switchgear configuration, protection devices, cable entry and LV outgoing circuits according to project requirements.
03
Designed for outdoor applications
The enclosure can be configured for outdoor installation with suitable ventilation, corrosion protection and ingress protection according to the local environment.
04
Simplified power distribution
By combining transformation and distribution equipment in one compact unit, the mini substation provides a practical solution between the MV network and multiple LV loads.
05
Why Choose a Chinese Transformer Manufacturer as Your Partner?
500kVA Mini Substations are commonly considered for:
● Industrial plants and workshops
● Commercial buildings and business parks
● Solar PV and renewable energy projects
● Construction sites and infrastructure
● Mining and remote power distribution
● Agricultural and rural electrification
● Warehouses and logistics facilities
● Residential or mixed-use developments
Project Reference
For example, a 500kVA mini substation can be configured for an industrial workshop where an 11kV incoming supply needs to be stepped down to 400V/415V for production equipment, lighting and auxiliary systems. The MV switchgear, transformer and LV distribution section are integrated into one compact assembly, reducing the need for separate equipment rooms.
