Construction of Medium and Low Voltage Electrical Systems and Substations
Level 1 MEP contractor QuangAnhcons excels in medium and low voltage electrical systems and substations construction with a skilled engineering team. QuangAnhcons commits to high technical and safety standards along with modern construction technology.
The process of constructing medium and low voltage electrical systems and substations requires high expertise in designing, installing, and operating the distribution system from the power source to the end customer. Key points include:
Medium voltage electrical systems play a crucial role in transmitting and distributing power at voltage levels from 1 kV to 35 kV. These systems use insulated or bare conductors installed on concrete poles from 9 m to 12 m to ensure safe distance and effective insulation. Maintaining stability and safety through medium voltage cabinets, protection cabinets, and control devices is essential.
Low voltage systems operate with voltages from 220 V to 380 V, primarily for residential and small business use. These systems use twisted pair cables or separate cables mounted on low poles from 5 m to 8 m to ensure insulation protection.
The substation is a critical center in the electrical system, facilitating voltage conversion from medium to low level for end-use needs. It includes transformers, control cabinets, cutting and protection devices.
The construction process starts with detailed installation schematic design, followed by pole line construction, substation installation, and final operational testing. Ensuring safety and stability is mandatory throughout the process, with periodic inspections and maintenance to maintain long-term reliability.
Specifically in medium voltage and substation construction, electrical safety is paramount. Optimal distance and insulation prevent discharge, with necessary protective equipment for workers.
Installing medium and low voltage systems and substations requires deep understanding of voltages and equipment, ensuring stable and safe power supply to end customers.
Professional Transformer Repair and Maintenance Services
Level 1 MEP contractor QuangAnhcons offers transformer repair and maintenance services in localities such as Dak Lak, Lam Dong. The company assures high quality with technical standards and CO, CQ certifications.
Professional transformer repair and maintenance services are vital for ensuring electrical safety and optimal performance in industrial electrical systems. The transformer maintenance process includes detailed technical activities to inspect conditions and promptly address issues.
The initial step is checking and maintaining detailed transformer contact points, including checking contact temperature, resistance, and insulating condition for safety and effective operation. Accessories like bolts and nuts are also thoroughly inspected.
Additionally, the transformer oil filtration process is crucial. Transformer oil acts as an insulator and heat dissipator, so filtering and drying the oil removes impurities, water, and tests the oil’s insulation resistance to ensure quality.
Supplementing or replacing transformer oil is performed when necessary to prevent fire and maintain device efficiency. Transformers are also fully cleaned, inspecting protective components and measurements like gas relays, oil flow relays, and porcelain sleeve transformers for electrical safety.
An important part is checking technical parameters like insulation resistance between parts and oil temperature measurement to detect and address abnormalities like noise or overheating. Transformer repairs include resolving issues like cracked porcelain and replacing faulty accessories.
After repair and maintenance measures, testing confirms operation stability and extends transformer lifespan. Consulting and fortifying transformer substation bases ensure stable operating environments, avoiding power supply disruptions.
For dry transformers, similar services include checking the magnetic core, high and low voltage cables for suitable maintenance plans. This process requires disconnecting the transformer from the grid for absolute safety during technical interventions.
Transformer services are designed to provide continuous and safe power supply, minimizing downtime, and optimizing repair costs.

Substation budget estimate
Select the capacity, route lengths and package to view your indicative budget and electrical parameters.
Request a project quotation
Send your project details, BOQ or drawings to request a formal quotation. Fields marked * are required.
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.
