Reliable and Efficient Transformer Repair Services in Lam Dong by Quanganhcons

Quang Anh Construction Co., Ltd (Quanganhcons) specializes in complete substation construction up to 35kV in Lam Dong, ensuring quality and safety.

Comprehensive Substation Construction

Quanganhcons executes comprehensive substation projects up to 35kV, covering works in Lam Dong. Using certified quality materials, Quanganhcons guarantees efficiency and safety.

Site Survey and Construction Positioning

Substation construction begins with an on-site survey to accurately position the build site. This requires experienced technicians working alongside investors and design consultants to determine the optimal site, particularly for medium voltage underground cable works.

Foundation and Underground Cable System Construction

The next step is constructing a robust foundation for the substation, along with trenching and installing protective conduit for cables. An earthing system is carefully installed to ensure electrical safety during operation.

Electrical Equipment Installation for Substations

Installing electrical equipment is a crucial step, involving disconnectors, operating platforms, crossarms, and transformers. Meticulous protection of insulation parts and precise equipment placement are vital to maintaining quality.

Connection, Acceptance, and Operation

Connecting operations must be performed with precision, accompanied by testing and quality checks. Final acceptance and trial operation are essential to ensuring the substation can operate steadily.

Warning Signs and Project Handover

Finally, warning signs are erected to ensure safety. Comprehensive acceptance documentation is compiled before the official handover to bring the substation into use.

Key considerations include preparing high-quality materials, using standard-compliant insulating materials, and designing a secure grounding system. Supervision by skilled technicians is necessary to ensure all processes run smoothly.

Transformer Repair Services in Lam Dong

Quanganhcons’ transformer repair services in Lam Dong ensure stable operation. Utilizing oil and dry transformers from brands like Thibidi and Siemens, they meet regional needs effectively.

Transformer repair services in Lam Dong are a crucial component in maintaining a safe and efficient power system. Repair and maintenance activities include scheduled servicing, comprehensive repairs, and detailed equipment overhauls. During transformer maintenance, minor servicing is conducted quarterly or semi-annually depending on operational conditions. This process does not require oil removal or opening the transformer core. Overhauls, on the other hand, are thorough maintenances encompassing drying out the transformer, replacing insulating oil as necessary, and inspecting the transformer following stringent technical standards.

When performing repairs, disconnecting the transformer from the power source is essential to ensure safety. The repair process includes:

• Cleaning and maintenance of transformer components.
• Drying, filtering, or replacing insulating oil.
• Inspecting and repairing devices connected to the transformer.
• Repainting the housing if necessary.
• System check and testing.

Ensuring stable transformer operation involves addressing sudden failures like component damage or insulating oil leaks. Such incidents often stem from factors like lifespan, working environment, or overload. Additional critical services include inverter repairs, warranty, and 24/7 technical support.

Setting up a maintenance routine for oil transformers and modern electrical repair services ensures that Lam Dong’s power system operates at peak efficiency and safety.

Stringent Process and Technical Standards

Quanganhcons follows stringent processes and high technical standards in the design, construction, and renovation of substations, ensuring safety and urban aesthetics.

Following rigorous processes and high technical standards is crucial for ensuring safety, quality, and reliability throughout the lifecycle of equipment and projects. This process comprises detailed steps, each playing a vital role in ensuring safety and quality.

An integral part of the process is device inspection, which adheres to strict requirements per Decree 44/2016/ND-CP and related circulars. This process begins with reviewing device documentation, including material composition documents, technical drawings, certificates of conformity, and other documents like calibration equipment logs or grounding/lightning protection inspection reports. Next, technical examinations of both the exterior and interior equipment are performed, accompanied by necessary tests like pressure or load tests. Following this, equipment is trial-operated in real conditions, and inspection results are processed and evaluated in detail; the final report must be signed by an expert technician along with a legal seal.

In the construction realm, strict technical procedures commence with geotechnical surveys, climatic condition assessments, followed by preparing design plans and structural calculations. This process also includes cost estimation, construction scheduling, and completing legal procedures like construction and fire safety permits. For construction project assessment, key phases include preliminary surveys, detailed measurements, material and structural testing, followed by presenting a legal conclusion report.

Equipment and projects must adhere to TCVN standards such as TCVN 8366 for pressure vessels, TCVN 6395 for elevators, and TCVN 4244 for lifting equipment. For operational safety, a standard operating procedure (SOP) and certified operator training are necessary. Only organizations certified 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 results.

The stringent technical process encompasses preparing documentation, material inspection, technical testing, trial operations, regular cyclical inspections, operator training, up to legally valid result reports according to national standards and legal regulations.
