With our extensive experience and expertise, we are committed to delivering top quality and absolute safety for our clients’ projects.

Services for New Factory Construction

Survey and Design: We conduct site surveys and assess the electrical needs of the factory, followed by designing electrical systems from 22kV to 35kV, including electrical schematics, switchboard design, and control systems.
Supply and Installation of Equipment: We provide and install high-quality equipment such as transformers, Main Switchboards (MSB), and Main Distribution Boards (MDB) from reputable brands. Our switchgear ensures compliance with stringent technical standards and operational safety.
Construction of Cable Trays and Low Voltage Power Cables: We supply and install cable trays and low voltage power cables manufactured and processed in Vietnam by leading brands, ensuring quality, durability, and adherence to environmental protection standards.
Electrical System Installation: Our professional installation process includes setting up electrical cabinets at transformer stations to MSB cabinets, from MSB cabinets to MDB cabinets, and from MDB cabinets to machinery in the factory, ensuring timely completion and high quality.

Services for Maintaining Factory Operations

Periodic Maintenance of Transmission Lines and Transformer Stations: We perform regular inspections and maintenance of medium voltage transmission lines and transformer stations to ensure stable and safe operations, and carry out repairs and upgrades when necessary.
Maintenance and Upgrading of MSB and MDB Systems: We inspect, maintain, and replace equipment in MSB and MDB to ensure efficient operation, and upgrade systems to meet expanding production needs or improve performance.
Inspection and Maintenance of Cable Trays and Low Voltage Cables: We conduct regular inspections of cable trays and low voltage cables to ensure safety and durability, and repair or replace them as needed to meet technical standards.
Inspection and Maintenance of Electrical Connections: We inspect electrical connections from switchboards to equipment within the factory to ensure stable operation, and maintain and repair faulty or inefficient connections.

Services for Factory Relocation

Planning and Surveying: We develop detailed plans for relocating electrical systems and survey the current setup to create a relocation plan for moving electrical systems from the old site to the new location.
Dismantling and Packing of Equipment: We dismantle transformers, MSB and MDB switchboards, power cables, and related equipment, pack and transport them to the new site.
Reinstallation and Connection of Electrical Systems: At the new location, we reinstall transformers, MSB and MDB switchboards, power cables, and connect the electrical system to the local power grid.
Testing and Commissioning: After reinstallation, we inspect the entire system to ensure safety and stable operation, conduct test runs, and calibrate the system to ensure optimal performance.
Technical Support and Supervision: We provide technical support during the relocation and reinstallation process and supervise the relocation to ensure project progress and quality.

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.
