Repair and Maintenance Services: Solutions for Ensuring Sustainable Operation

In today's industrial and electrical infrastructure environment, ensuring that electrical equipment operates stably, safely, and continuously is one of the vital factors. Repair and maintenance services are not just "patching errors" when incidents occur, but a strategy to protect the lifespan, performance, and minimize risks in the operation of electrical equipment.

Trường Giang Electric Company (TGE) proudly provides comprehensive repair and maintenance services, with a presence across all three regions and a commitment to fast, professional service.

 

1. Why is periodic repair and maintenance necessary?

1.1 Minimize unexpected failures An electrical device operating continuously under load or in harsh environmental conditions (temperature, humidity, dust, corrosion) is prone to sudden breakdowns—causing production interruptions, safety hazards, or significant property damage.

1.2 Extend equipment lifespan Early detection of signs of degradation—such as loose contacts, corrosion, high temperatures—and timely remediation help prolong the lifespan of machinery, switchgear, circuit breakers, and switching devices.

1.3 Ensure operational efficiency Equipment undergoing periodic maintenance will operate close to its designed technical specifications, reducing energy losses and ensuring stable current flow.

1.4 Safety for people and property Damaged circuits, electrical leaks, loose contacts, or poor insulation can cause short circuits, fires, explosions, or accidents—inspecting and repairing faults as soon as they are detected helps prevent these risks.

1.5 Optimize long-term costs The cost of major repairs due to severe damage is often much higher than the cost of periodic maintenance. Investing in maintenance is a preventive investment, helping to save overall costs over the equipment's lifecycle.

 

 

2. TGE's commitments and strengths in repair and maintenance services

2.1 Rapid response: On-site within 12 hours TGE commits to a widespread service team, meeting customer requirements and arriving at the site within 24 hours from receiving the request.

2.2 Extended warranty up to 3 years Equipment after repair is guaranteed with a warranty to give customers peace of mind during operation.

2.3 Readily available replacement components To avoid prolonged interruptions, TGE always maintains ready stock of components and modules for immediate on-site replacement when necessary—ensuring continuous operation for customers.

2.4 Long-term maintenance contracts with major projects A testament to trust is TGE's signing of framework contracts for the maintenance of all medium voltage switchgear for power companies. This demonstrates capability, reputation, and reliability in actual operations.

 

3. Scope of repair and maintenance services

A genuine repair and maintenance service includes various technical items, from inspection and prevention to incident handling. Below are common items:

Item	Description of Work
Inspection and Diagnosis	Measure insulation resistance, measure leakage current, check contacts, check voltage drop, check temperature (using infrared camera)
Cleaning & Sanitization	Remove dust, soot, conductive deposits; clean surfaces, remove oxides, insulate
Tighten Contacts	Joints, cables, terminals, contact rods—ensure no looseness, good contact
Lubrication / Insulating Oil	Replenish insulating oil, anti-oxidants, metal protection
Replacement of Equipment - Materials	Replace contactors, switching devices, fuses, contacts.
Alignment & Calibration	Repair and adjust, calibrate parameters of control and protection devices.
Post-Repair Testing	Operational testing, insulation measurement, current measurement, temperature monitoring after repair
Reporting & Consultation	Detailed recording of performed items, equipment status, recommendations for the next maintenance cycle

 

For example, in a medium voltage switchgear station, when inspection using an infrared camera detects an abnormally high hot spot, technicians will identify loose contacts or uneven contact pressure, proceed to tighten, clean, or replace contacts, then retest to ensure stability.

 

4. Service process – from receipt to completion

To ensure transparency, efficiency, and quality control, TGE applies the following standard process:

1. Receive customer request

Customers contact via hotline, email, or website form to submit repair/maintenance requests.

2. Analysis & on-site survey

Technical team provides preliminary consultation, then dispatches personnel for on-site survey and equipment condition assessment.

3. Planning & detailed quotation

Based on the survey, prepare a detailed table of required items, replacement materials, labor, time; submit to customer for approval.

4. Approval & implementation

After customer approval, the technical team implements according to the schedule and safety procedures.

5. Inspection & acceptance

Upon completion, conduct testing and verification, perform acceptance with the customer, prepare handover minutes.

6. Warranty & post-repair support

During the warranty period (up to 3 years), if the equipment has issues, TGE provides remediation according to the signed terms.

7. Periodic maintenance cycle

For customers with long-term contracts, TGE will perform periodic maintenance (quarterly, semi-annually, or annually) according to the agreed schedule.

5. Factors customers should consider when selecting a repair and maintenance provider

• Experience & reputation: check completed projects, customer references.
• Legal status & certifications: electrical engineers with certificates, electrical safety licenses
• Response time & warranty: a good provider will commit to fast on-site arrival and long-term warranty
• Technology & supporting equipment: use infrared cameras, high-end measuring devices, genuine replacement components
• Transparent cost policy: clear quotations, detailed maintenance contracts, avoid uncontrolled extras
• Multi-regional capability: if the customer has multiple locations, select a provider with widespread network coverage

6. Advice to optimize repair and maintenance services

• Establish periodic maintenance contracts: plan periodic maintenance from the outset in the contract to avoid interruptions and unexpected costs.
• Record and archive reports: every repair and maintenance must have detailed minutes and be archived to track equipment progress over time.
• Remote monitoring & IoT usage (if possible): apply sensors, monitoring systems to detect early abnormalities such as high temperatures, over-threshold currents.
• Train operating personnel: on-site staff need training on safe operation, early detection of abnormal signs to report to technicians.
• Budget for spare materials: always have critical components in stock for quick replacement, avoiding long waits from suppliers.
