General Contractor QuangAnhcons: Professional in Industrial Electrical System Construction

General Contractor QuangAnhcons is deeply engaged in the construction of industrial electrical systems and infrastructure, integrating modern technology and equipment to ensure quality and operational efficiency.

Efficient Underground Electrical System Construction

General Contractor QuangAnhcons stands out with its efficient underground electrical system construction, using modern machinery technology such as robotic drilling for underground cable pulling and trench excavation. Thanks to this advanced technique, QuangAnhcons has minimized environmental impact, ensuring projects are completed swiftly while maintaining construction quality and customer satisfaction. This is a crucial factor in building trust and maintaining the reputation of General Contractor QuangAnhcons in the industry.

To ensure that the underground electrical system provides maximum safety and meets technical requirements, the application of advanced technology and processes is essential.

1. Underground Tunnel Boring Technology (TBM)
   The use of TBM technology, especially EPB and Slurry types, plays an important role in handling complex geology. TBM helps reduce landslide risks and enhances construction quality when constructing underground electrical systems. This is an optimal choice for projects with difficult geological conditions.

2. Underground Cable Laying Process
   During the construction of underground cable systems, appropriate depth trenches (usually ≥1.2m) must be dug to lay the conduit. The use of HDPE plastic pipes and standard bedding methods like sand or concrete helps protect the cables from damage. The pulling-pushing method must be executed precisely to avoid cable twisting or damage.

3. Modular Construction Technology in Underground Electrical Stations
   Using precast components combined with high-pressure grout improves construction efficiency. This process not only increases durability but also ensures precise component assembly, enhancing overall quality for the underground electrical construction.

4. Trenchless Technology Method
   This method is applied in restricted construction areas, such as workers using pipe jack techniques or horizontal directional drilling to execute underground electrical projects without significantly affecting the ground and surrounding infrastructure.

5. Technical Factors to Consider
   Choosing heat-resistant materials, controlling groundwater, and ensuring soil reinforcement processes are critical to ensuring effective, sustainable, and safe underground electrical systems. Regular electrical quality monitoring is also indispensable for early detection and timely handling of potential incidents.

35kV Transformer Station Solutions and Beyond

QuangAnhcons provides transformer station solutions up to 35kV, an indispensable part of industrial electrical systems. With solid experience and a team of experienced engineers, QuangAnhcons ensures that transformer stations are designed and installed accurately, optimizing operational efficiency. Customers can be assured of the quality and reliability of the system, which not only enhances economic efficiency but also ensures labor safety.

The 35kV transformer station plays an important role in the medium voltage electrical system, especially in converting voltage from 35kV down to lower levels like 22kV or 0.4kV, suitable for supplying electricity to factories and industrial zones. Two-voltage level transformers (35(22)/0.4kV) are a popular choice nowadays due to their flexibility in changing between 35kV and 22kV by simply adjusting the tap changer. This helps significantly reduce costs when upgrading or standardizing the electrical grid in the future.

The designs of 35kV transformer stations must comply with TCVN technical standards, specifically the electrical system must meet standards like TCVN 6306 (IEC 60076) along with quality certifications ISO 9001:2015 and ISO 14001:2015. These factors ensure high performance and safety during operation. A standard transformer station typically includes equipment such as transformers, circuit breakers, drop-out fuses, surge arresters, and compatible medium voltage cabinets or insulators for the 35kV voltage level.

The modern trend of transformer station solutions focuses on integrating electrical automation technology in switching and protection systems. This technology not only increases operational performance but also ensures high reliability and safety for medium voltage electrical systems. This is especially important when arranging surge arrester systems as well as earthing systems according to IEC 60076 standards to minimize risks from overvoltages and potential electrical incidents.

Maintaining the 35kV transformer station regularly is necessary to sustain performance and safety. The maintenance process includes periodic inspection of the tap changer and operational testing of the drop-out fuse every 6 months. This ensures that the systems always operate at their best state, while two-voltage transformers continue to be used to maintain flexibility, supporting the upgrade or voltage adjustment along the 22kV grid standardization roadmap.

Developing Sustainable Energy and Rapid Electric Vehicle Charging Stations

In the trend of developing sustainable energy, General Contractor QuangAnhcons focuses on investing in solar energy solutions and designing rapid charging stations for electric vehicles. These solutions not only help customers optimize energy sources but also contribute to environmental protection. QuangAnhcons has been committed to supporting customers in transitioning to clean energy solutions that meet all modern technical needs and ensure long-term benefits.

The development of sustainable energy is becoming a key strategy in Vietnam, where transitioning to renewable energy plays a pivotal role. Developing energy sources such as solar power, wind power, and biomass not only aims to meet high electricity consumption demands but also helps reduce emissions, strengthening national energy security. By 2035, Vietnam aims to increase renewable energy capacity to about 150,000 MW, especially prioritizing solar and wind power. This increase not only creates favorable conditions for economic development but also protects the sustainable environment.

An integral part of this sustainable energy model is the development of rapid charging stations for electric vehicles, although technical details and specific plans have not yet been widely published. However, the role of rapid charging stations is undeniable as they support the growing demand for electric vehicles – an environmentally friendly technology. This is an important step towards reducing reliance on oil and lowering greenhouse gas emissions in the transportation sector.

In Vietnam, supporting policies are being finalized to accelerate public investment in renewable energy and essential infrastructure like rapid charging stations. As in Ninh Thuan, the construction of research and application centers for renewable energy technology has affirmed the region’s potential for green energy development, serving not only production but also clean transportation.

The strategy for developing sustainable energy and a network of rapid charging stations is part of the energy transition process in Vietnam. This ensures a stable, clean energy supply while meeting the objectives of economic development and reducing greenhouse gas emissions according to the guidelines of the Government and international organizations like the World Bank.
