QuangAnhcons: Professional and Comprehensive MEP Contractor


QuangAnhcons is a specialist in constructing and building medium to low voltage electrical systems and related services in Vietnam, with a variety of job categories and full-package services, highly regarded for its reputation and quality.

Construction of transformer station and electrical system

QuangAnhcons specializes in constructing various types of medium to low voltage transformer stations such as suspended, pad-mounted, compact kiosks, and indoor stations. These services ensure high technical and aesthetic standards, meeting all customer power demands. QuangAnhcons engineers always apply advanced technologies and equipment to optimize operational efficiency and transformer station lifespan.

The construction of transformer stations and electrical systems is a crucial process in the construction and energy field. The process starts with a site survey to determine the most effective location for installing transformer stations and medium voltage cables. Engineers must ensure that the survey and marking are technically accurate, coordinating with relevant parties to optimize the design.

Next is site preparation, involving clearing the area, providing electricity, water supply, and necessary necessities. Electrical materials such as transformers, switchboards, circuit breakers, and cables are also fully gathered to ensure construction progress.

The foundation construction is thoroughly executed, from digging to pouring concrete. Technical standards for size, flatness, and load-bearing capacity are crucial factors for the stable operation of the transformer station.

The grounding system is an important next step. Optimizing the grounding system ensures electrical safety, minimizes leakage, and protects both equipment and operators.

During the support system installation, switches, seating mounts, cross arms, and auxiliary devices are installed to facilitate operations and maintenance. The installation of transformer stations and electrical equipment follows, presenting a challenging task requiring high precision, using equipment like cranes and forklifts to place devices accurately.

Pulling and connecting medium voltage cables demands accuracy and adherence to circuit diagrams, ensuring safety and precision during connections. The next step involves installing nameplates and danger warning signs to protect workers and operational staff.

Afterward comes the testing and calibration phase, where engineers check resistance, insulation, and perform initial operation tests to ensure the transformer station’s functionality. Finally, the acceptance and trial operation phase ensures all equipment operates safely and efficiently before handing it over to the customer.

During construction, using equipment from renowned brands like ABB, Schneider, or Cadivi, combined with electrical surveys, enhances the quality and reliability of the project, meeting customer power needs effectively.

Building and undergrounding the electrical grid

In constructing and undergrounding electrical grids, QuangAnhcons performs jobs such as deploying medium to low voltage underground cables, using advanced techniques like road-crossing robotics drilling, trench excavation, and putting in protective pipes. These solutions ensure stable power supply to businesses and factories while minimizing environmental impact.

Undergrounding electrical grids plays a vital role in enhancing electrical infrastructure and preserving urban landscapes. In Ho Chi Minh City, undergrounding medium to low voltage grids is part of a long-term strategy that EVNHCMC has been implementing. The goal is to complete the basic undergrounding of electrical grids in urban areas by 2030, achieving a high level of undergrounding.

During 2021-2025, EVNHCMC focuses on undergrounding 1,850 km of medium and low voltage power lines and telecommunications cables. In central districts like District 1 and District 3, the plan targets 80-90% low voltage and 100% medium voltage grids undergrounding. For suburban districts like Cu Chi, Can Gio, Binh Chanh, and Hoc Mon, undergrounding plans are deployed from main roads to expand and standardize electrical infrastructure.

The benefits of undergrounding electrical grids are clear. Undergrounding not only enhances urban beauty by removing overhead poles and cables but also improves power stability by minimizing cable breaks or pole falls. Moreover, the underground grid system better protects against natural disasters like storms and floods, ensuring energy security.

The success of this process in HCMC has been proven over 20 years with a significant increase in the medium voltage grid undergrounding rate from 35% to 60%, depending on the area during 2011-2020. This foundation continues to expand undergrounding to suburban and new urban areas like Thu Duc.

Advanced technical solutions are applied in undergrounding, including modern standards ensuring easy maintenance and upgrade in the future. Undergrounding is synchronized with urban planning, contributing to a sustainable, modern, and environmentally friendly electrical infrastructure.
