Proper maintenance of underground power lines is crucial for ensuring long-term reliability and preventing costly failures. Our clients use a proactive approach that includes:

• Preventive Maintenance: This involves routine inspections of above-ground equipment like pad-mounted transformers and switchgear for signs of wear. Infrared thermal imaging is a key technique used to detect "hot spots" at terminations and splices that may indicate a developing problem.

• Predictive Maintenance: Advanced testing, such as partial discharge (PD) testing, is performed on the cable system to detect early signs of insulation degradation before a failure occurs.

• Corrective Maintenance: When a fault is detected, specialized cable fault locators are used to pinpoint the exact location, allowing for targeted excavation and repair. The use of professional-grade tools for splicing and termination ensures that the repaired section is as reliable as the original.
