Professional MEP Contractor QuangAnhcons: Leading Electromechanical Solutions

QuangAnhcons is a leading MEP (mechanical, electrical, and plumbing) contractor in Vietnam, specializing in the design and construction of industrial electrical systems and electromechanical solutions for large factories.

Industrial Electrical System Construction

QuangAnhcons excels in underground electrical system construction, low voltage, and medium voltage grids. We ensure safe, cost-effective, and sustainable operations by professionally designing and constructing substations up to 35kV.

Industrial electrical system construction is a precise task requiring strict adherence to technical standards and industrial electrical safety. This process involves several crucial steps carried out sequentially and involves technical and safety considerations.

1. Equipment Preparation:

• Ensure sufficient equipment for the project, including underground systems, low voltage grids, and 35kV substation components.
• Deploy a comprehensive construction schedule plan, optimizing costs and minimizing energy waste.

1. Project Survey and Information Gathering:

• Conduct field surveys, collect necessary data about actual conditions and technical requirements to ensure precise medium voltage electrical construction.
• Receive and analyze customer requirements to ensure the design matches long-term use goals and expectations.

1. Design Electrical System Drawings:

• From the collected data, system engineers will design detailed underground electrical system drawings and propose optimizations for low voltage grids.
• Drawings are submitted to customers for approval to ensure reasonability and efficiency before actual implementation.

1. Electrical System Installation:

• Installation must comply with approved standards, ensuring safety for both workers and equipment used in 35kV substations.
• Commitment to guarantee the effectiveness and stability of the industrial electrical system after installation.

1. Acceptance and Inspection:

• After installation is completed, the system must be thoroughly tested to confirm stable and safe operation.
• The acceptance process must be carefully performed before handing over the system to customers.
• Begin the warranty and maintenance phase, optimizing operation and providing long-term support services.

Important factors include safety at work, commitment to stable system operation, and adherence to established standards. Optimizing operation and reducing energy consumption are also top priorities in industrial electrical system construction.

Substation and EV Charging Station Design and Construction

QuangAnhcons pioneers the provision of substation and electric vehicle (EV) charging station construction services, applying modern technology to promote green industrial transition. We use equipment from reputable brands like ABB, Schneider, ensuring durability and efficient operation.

In the context of modernization and green transition, substation and EV charging station design and construction have become increasingly important for electrical systems in Vietnam.

Technical Standards and Substation Design Process

Substations are essential components for efficient and safe power transmission. Necessary technical standards must be strictly adhered to, including:

• TCVN 3715-82: Regulations on complete substations to 1000 kVA, voltage up to 20 kV for 3-phase AC systems, frequency 50Hz. Applicable for both indoor and outdoor substations.

• TCVN 8096-202:2017 and TCVN 9142:2012: Provide technical requirements for pre-assembled substations and substation design, installation standards.

Basic Design Process:

1. Site Survey:

• Ensure the location is near the load center to reduce the power distribution radius.
• Convenient for connection to supply sources and easy construction.

1. Choose Transformer Type:

• Choose the appropriate transformer type: outdoor, indoor, pole-mounted…

1. Design Electrical Schematics and Equipment Layout:

• Develop post-connection device schematics to ensure safety.
• Choose modern equipment that meets Vietnamese standards.

Substation Construction

The construction process must be rigorously followed:

• Prepare connection documents and necessary technical paperwork.
• Construct foundations, structures, install transformer and electrical cabinet equipment.
• Perform thorough inspections and acceptance tests before commissioning.

EV Charging Station Design and Construction

Although there are no specific standards for EV charging stations, applying substation design principles ensures safe and stable power supply.

Design considerations include:

• Provide stable and safe power supply for the charging station.
• Convenient installation location, fire and explosion prevention.
• Integrate electronics for safe charging management.

EV charging station construction requires:

• Install equipment according to technical procedures.
• Inspect electrical and protective systems before usage.

Thanks to the development of green technology, projects like substations and EV charging stations not only serve usage needs but also significantly contribute to sustainable development and environmental protection.

Renewable Energy and Solar Power Solutions

As a leading EPC contractor, QuangAnhcons provides renewable energy solutions, especially solar power under the ESCO model. We help customers install systems without initial investments, optimizing economic efficiency and environmental protection.

Renewable energy and solar power solutions are being strongly developed in Vietnam thanks to policies and strategic directions aimed at increasing the share of green energy. With favorable natural conditions, Vietnam stands out with strong solar energy potential, especially due to the average radiation intensity of 4-5 kWh/m²/day in the North and higher in the Central and South with 5 kWh/m²/day. This creates an ideal opportunity to develop large-scale and distributed solar power systems.

The Vietnamese government has issued Decree 58/2025/ND-CP, effective from March 2025, clearly stipulating incentives and legal frameworks for renewable energy development. The goal is to increase the share of green energy sources to 30% by 2030 and 44% by 2045, along with a commitment to reach Net Zero by 2050. Power Planning VIII is established to adjust to increasing electricity demand, ensuring national energy security and reducing greenhouse gas emissions.

As of April 2025, 63 renewable energy projects have been approved with a total capacity of over 3.429 MW, of which 30 plants are operational, producing over 6 billion kWh of renewable electricity. High-tech trends like high-efficiency photovoltaic cells are being widely applied, significantly improving solar energy exploitation efficiency.

Despite many incentives, renewable energy development in Vietnam still faces significant challenges, particularly during the 2026-2028 period. Increasing investment and improving planning are necessary to meet demand while resolving investment procedure obstacles to promote sustainable economic development in industrial and commercial fields.

The shift to renewable energy not only contributes to energy security but also supports sustainable development and environmental protection, thus opening up numerous new business opportunities for enterprises.

QuangAnhcons provides advanced industrial electromechanical systems with cost-saving solutions. We ensure long-term stability and operation, thanks to a skilled engineering team and modern equipment.
