Quanganhcons reliable and effective transformer repair in Lam Dong

Quang Anh Electrical Installation Co., Ltd (Quanganhcons) specializes in providing comprehensive construction of substations up to 35kV in Lam Dong, ensuring quality and safety.

Comprehensive construction of substation types

Quanganhcons undertakes comprehensive construction of various types of substations up to 35kV, including projects in Lam Dong. Using quality-certified materials, Quanganhcons commits to efficiency and safety.

Surveying and positioning construction

Substation construction begins with practical surveying to accurately position the construction site. This requires an experienced technical team, working together with investors and design consultants to determine the optimal location, especially for medium voltage underground cable construction.

Foundation construction and underground cable system

The next process involves constructing a solid foundation for the substation, along with trench digging and installing protective conduit for cables. An earthing system is also carefully constructed to ensure electrical safety throughout operation.

Electrical device installation for substations

Installing electrical devices is a crucial step, including switches, operating chairs, crossbars, and transformers. Careful protection of insulating parts and precise fixing of devices is vital to ensure quality.

Connection, inspection, and operation

The connection task must be carried out accurately, combined with tests and quality assurances on the installation. Inspection and trial operation are indispensable stages to ensure the substation can operate stably.

Warning signs and project handover

Finally, danger warning signs are installed to assure safety. Inspection records are compiled before handing over to put the substation into official use.

Important points to consider include preparing quality materials, using standard-compliant insulating materials, and designing a safe earthing system. Supervision by skilled technicians is necessary to ensure that all processes run smoothly.

Transformer repair service in Lam Dong

The transformer repair service in Lam Dong of Quanganhcons ensures stable operation. Utilizing oil-filled transformers and dry transformers from brands like Thibidi, Siemens, serving the local needs well.

The transformer repair service in Lam Dong is an essential factor to ensure the electrical system is safe and efficient. Maintenance and repair activities of transformers include regular maintenance, comprehensive repairs, and overhauls. In the transformer maintenance process, minor maintenance is performed quarterly or every six months depending on operating conditions. This process does not require draining oil or opening the transformer’s core. Overhaul, on the other hand, is comprehensive maintenance including drying the transformer, replacing insulating oil if necessary, and inspecting the transformer according to strict technical standards.

When conducting repairs, it is necessary to disconnect the transformer from the power source to ensure safety. The repair process includes:

• Cleaning and sanitizing transformer parts.
• Drying, filtering, or replacing insulating oil.
• Inspecting and repairing devices connected to the transformer.
• Repainting the casing if necessary.
• Inspecting and testing the system.

To ensure the transformer operates stably, addressing unexpected issues such as component failures, insulating oil leaks is crucial. These incidents often stem from factors like lifespan, work environment, or overload. Essential services include inverter repair, warranty, and 24/7 technical support.

Setting up an oil transformer maintenance process and contemporary electrical repair services ensures the electrical system in Lam Dong always operates at optimal efficiency and highest safety.

Strict technical standards and processes

Quanganhcons adheres to strict processes and high technical standards in designing, constructing, and renovating substations, ensuring urban safety and aesthetics.

To ensure safety, quality, and reliability throughout the life cycle of equipment and construction, adherence to strict processes and technical standards is indispensable. This process involves many detailed steps where each stage plays an important role in ensuring safety and quality.

An indispensable part of the process is the inspection of equipment with strict requirements under Decree 44/2016/ND-CP and related circulars. This process begins with checking the equipment’s profile, including documents on material composition, technical drawings, conformity certificates, and many documents such as metrology equipment calibration records or ground/lightning protection test reports. Next is performing external and internal technical inspections on the equipment, conducting necessary tests such as pressure or load tests. After that, the equipment is tested in real-world conditions, and the results are processed and evaluated in detail, with the final report signed by a technical specialist along with the legal entity’s seal.

In the construction field, strict technical processes start from geotechnical surveys, climate conditions, then designing and calculating the technical structure. This process also includes cost estimation, construction schedule, and completing legal procedures such as construction permits and fire prevention and control. For construction work inspection, the main steps include preliminary surveys, detailed measurements, material and structure testing, and then drafting legal conclusions reports.

Equipment and constructions must comply with TCVN standards such as TCVN 8366 for pressure vessels, TCVN 6395 for elevators, and TCVN 4244 for lifting devices. For operational safety, standard operating procedures (SOP) and certified operator training are required. Only organizations with competency certificates issued by the Ministry of Construction or the Ministry of Labor – Invalids and Social Affairs are authorized to inspect equipment, ensuring the reliability and legality of the results.

Strict technical processes include preparing documents, material inspections, technical testing, trial operations, regular cycle inspections, operator training, to producing legally valid reports according to national standards and legal regulations.
