Transformer Station Construction Services

Introduction
Transformer stations are the backbone of any industrial electrical infrastructure. They play a critical role in stepping down or stepping up voltage to ensure the smooth operation of machinery and the stability of energy supply for industrial parks and factories. At QuangAnhcons, we specialize in designing, constructing, and maintaining transformer stations tailored to meet the diverse needs of both local and foreign-invested enterprises (FDI) in Vietnam.

What We Offer
Our comprehensive services for transformer station construction include:

Design and Consultation: Customized transformer station designs based on project specifications, regulatory compliance, and energy optimization.
Installation and Testing: Expert installation of equipment, thorough testing, and grid integration.
Maintenance and Upgrades: Regular maintenance to ensure optimal performance and extend the lifespan of the station.

Economic, Social, and Environmental Impact

Economic Growth: Our projects support the growth of Vietnam’s industrial sector by providing reliable energy solutions that attract FDI and enhance production capacity.
Social Benefits: Reliable electricity infrastructure ensures operational continuity, creating stable jobs and improving local living standards.
Environmental Responsibility: We prioritize sustainable construction practices, integrating renewable energy solutions where possible and minimizing ecological impacts.

Technical Highlights

Capacity Range: From 3x15kVA to 7500kVA, meeting diverse industrial requirements.
Compliance: Adherence to international standards such as IEC, ensuring safety and reliability.

Quotation scope

Applies to one EVN-supplied substation with oil-immersed transformers at 22/0.4 kV (single-phase: 12.7/0.23 kV), with MV metering VTs/CTs supplied by EVN. The estimate includes the selected equipment, installation, earthing, transformer-to-main-breaker connections, design and connection documentation, and coordination of testing and utility acceptance.

Kiosk, integrated steel-pole and indoor substations include MV switchgear and the entered underground cable route. Other outdoor arrangements use the relevant protection configuration. The final diagram must meet the project connection requirements.

Excludes VAT, cables from the substation switchboard to the MSB/loads, live-line work, harmonic reactors, weak-ground treatment or special piling, land and special fire-protection provisions. Underground routes assume normal construction conditions and exclude road drilling and special reinstatement.

Prices are indicative investment budgets. A formal quotation follows site assessment and agreement on the configuration. Electrical selections are preliminary and require design verification before installation.

Capacity range and application conditions

The catalogue defines the enquiry range of this tool, not universal TCVN capacity limits. Single pole-mounted transformers: 15–100 kVA; three-unit banks: 3×15–3×100 kVA. Platform substations: 100–630 kVA. Steel-pole substations: 100–630 kVA; 750/800 kVA require design verification and local approval. Ground-mounted, kiosk and indoor configurations: 50–10,000 kVA. Not every configuration has a package price or the same structural design.

Reference: EVN Decision 1299/QD-EVN dated 3 November 2017, Volume 1, sections 3.3–3.4. Check the current requirements of the responsible utility before implementation. Kiosks must meet manufacturer ratings and testing requirements (IEC 62271-202); indoor and ground-mounted arrangements must meet project layout, ventilation, structural and fire-protection requirements. For multiple transformers, specify the quantity and capacity of each unit.
