QuangAnhcons Electrical Contractor: Expert in Industrial Power Systems

QuangAnhcons Electrical Contractor excels in specialized construction of industrial and infrastructure electrical systems, integrating modern technology and equipment to ensure quality and operational efficiency.

Efficient underground power system construction

QuangAnhcons Electrical Contractor stands out with its efficient underground power system installations, utilizing modern technology such as robotic drilling for cable trenching. This advanced technique minimizes environmental impact and ensures project completion swiftly, maintaining construction quality and customer satisfaction. This is a key factor in building trust and sustaining QuangAnhcons’ reputation in the industry.

For maximum safety and compliance with technical standards, the use of advanced technology and processes is essential in underground power systems.

1. Underground tunnel construction technology (TBM – Tunnel Boring Machine)
   The use of TBM technology, particularly machines like EPB and Slurry, plays a crucial role in addressing complex geological conditions. TBM reduces the risk of landslides and enhances project quality during underground electrical system construction, making it an optimal choice for challenging geological projects.

2. Underground cable construction process
   In underground cable installation, a trench of appropriate depth (usually ≥1.2m) is essential for laying conduit pipes. Using HDPE pipes and standard backfill methods such as sand or concrete protects cables from damage. Accurate pull-push techniques are critical to prevent cable twisting or damage.

3. Pre-fabricated installation technology in underground substations
   Incorporating pre-cast components with high-pressure mortar spraying boosts construction efficiency. This process not only enhances durability but also ensures precise linkage of major components, improving overall quality in underground electrical projects.

4. Trenchless technology
   This method is applied in constrained construction areas, using techniques like pipe jacking or horizontal directional drilling for underground electrical projects without significantly impacting the surface and surrounding infrastructure.

5. Key technical considerations
   Choosing heat-resistant materials, managing groundwater, and ensuring soil stabilization are crucial factors for safe, effective underground power systems. Continuous quality monitoring is indispensable for early detection and timely resolution of potential issues.

35kV transformer station solutions and beyond

QuangAnhcons offers transformer station solutions up to 35kV, essential in industrial electrical systems. With solid experience and skilled engineers, QuangAnhcons ensures precise design and installation of transformer stations, optimizing performance. Clients can rely on the quality and reliability of these systems, enhancing economic efficiency and labor safety.

The 35kV transformer station is critical in medium-voltage systems, especially in voltage conversion from 35kV to lower levels like 22kV or 0.4kV, meeting the electrical supply needs of factories and industrial zones. Dual-voltage transformers (35(22)/0.4kV) are popular for their flexibility to switch between 35kV and 22kV by adjusting the voltage tap. This significantly reduces costs for future grid upgrades or standardization.

35kV transformer station designs must comply with TCVN technical standards, ensuring adherence to standards like TCVN 6306 (IEC 60076) along with ISO 9001:2015 and ISO 14001:2015 quality benchmarks. These factors guarantee high performance and safety during operation. A standard transformer station usually includes equipment like transformers, circuit breakers, drop-out fuses, lightning arresters, and compatible medium-voltage switchgear or insulators for 35kV systems.

The modern trend of transformer station solutions focuses on integrating electrical automation technology in switching and protection systems. This not only boosts performance but also ensures high reliability and safety in medium-voltage systems. This is especially important in arranging lightning protection and grounding systems to IEC 60076 standards to mitigate overvoltage risks and potential electrical incidents.

Regular maintenance of 35kV transformer stations is crucial for ensuring performance and safety. The maintenance process includes regular tap position checks and operating drop-out fuse tests every 6 months. This ensures systems remain in peak condition, with dual-voltage transformers continuing to be used for flexible voltage upgrades or adjustments in a 22kV grid standardization plan.

Advancing sustainable energy and EV fast charging stations

Aligning with sustainable energy trends, QuangAnhcons invests in solar energy solutions and designs fast-charging stations for electric vehicles. These initiatives not only help clients optimize energy resources but also contribute to environmental protection. QuangAnhcons is dedicated to supporting clients in transitioning to clean energy solutions, meeting modern technical needs and ensuring long-term benefits.

Sustainable energy development is a critical strategy in Vietnam, where transitioning to renewable energy is crucial. Developing energy sources like solar, wind, and biomass addresses high electricity demands while reducing emissions and enhancing national energy security. By 2035, Vietnam aims to increase renewable energy capacity to about 150,000 MW, with a keen focus on solar and wind power. This growth not only fosters economic development but also ensures environmental sustainability.

An integral part of this sustainable energy model is the development of fast-charging stations for electric vehicles, though specific technical details and plans are yet to be widely disclosed. The importance of fast-charging stations is undeniable as they foster the adoption of electric vehicles—a technology with environmental benefits. This is a crucial step towards decreasing oil dependence and reducing greenhouse gas emissions in transportation.

In Vietnam, policies are being refined to hasten public investment in renewable energy and necessary infrastructure like fast-charging stations. Such development in regions like Ninh Thuan has highlighted the area’s potential in renewable energy, not just for production but also for clean transport.

The strategy for sustainable energy development and fast-charging networks is part of Vietnam’s energy transition journey. This ensures a stable, clean energy supply while achieving economic development goals and reducing greenhouse gas emissions in line with Government and international organization objectives like the World Bank.
