Substation operation & maintenance

You focus on production – we take care of your substation: safe operation, maintenance on schedule, early detection of defects and fast fault response.

Overview

The substation is the heart of a factory's power supply. A small issue such as an overheating joint or a dirty insulator can trip the whole plant and cause heavy production losses.

Du Long Power directly operates 11 substations with a total capacity of 13,400 kVA in Du Long Industrial Park. We apply the same procedures, team and specialized equipment to your substation.

Scope of service

  • Substation operation on your behalf under electrical safety procedures
  • Scheduled inspection and maintenance of transformers and switchgear
  • Periodic electrical equipment testing as required by regulations
  • Infrared thermography to detect hot spots
  • Insulator cleaning and re-tightening of connections
  • Fault repair and replacement of damaged equipment

Benefits for your business

  • Less unplanned downtime

    Early signs of abnormality are detected before they cause outages.

  • Longer equipment life

    Transformers and switchgear are maintained properly and run reliably for longer.

  • Safety compliance

    Complete operating logs and test reports, ready for inspections by authorities and insurers.

  • Lower staffing costs

    No need for an in-house operations team; fixed, predictable cost.

Frequently asked questions

How often should a substation be maintained and tested?
Routine inspections are carried out monthly or quarterly; equipment testing follows the cycle required for each type of equipment. A specific schedule is set in each substation's maintenance plan.
Does maintenance require shutting down the factory?
Some tasks, such as infrared scanning, are done with the substation on load. Tasks requiring a shutdown are scheduled on days off or at times you propose, to avoid disrupting production.
What is infrared thermography for?
Infrared cameras reveal abnormal hot spots at joints, terminals and switchgear – early signs of poor contact or overload – so they can be fixed before a failure occurs.
How quickly can your team arrive when a fault occurs?
Our technical team is on duty 24/7 in Du Long Industrial Park and reaches the site promptly after notification.
