Low voltage, medium voltage and high voltage cables form the core of power systems infrastructure. Therefore, maintaining their reliability and safety is crucial in order to avoid service interruptions resulting from cable faults such as open circuit, short circuit, intermittent faults and earth faults.

Benefits of MV and LV Cable Operation and Maintenance

Reliability Enhancement
Regular maintenance minimizes cable failures, reducing downtime and ensuring a continuous and reliable power supply to your facility.

Safety Assurance
Well-maintained cables reduce the risk of electrical faults, which can lead to fire hazards, unplanned power outages, and safety hazards for personnel.

Cost Savings
Proactive maintenance helps identify and address potential issues before they escalate, avoiding costly emergency repairs and replacements.

Optimal Performance
Maintenance measures, such as cleaning, insulation testing, and repairs, ensure cables operate at their maximum efficiency, contributing to energy savings.

Compliance and Longevity
Adhering to maintenance standards and schedules extends the lifespan of cables and ensures compliance with industry regulations.

Initial Assessment
Conduct a thorough assessment of the MV and LV cable infrastructure, including visual inspections, cable condition assessment, and documentation review.

Maintenance Strategy Development
Based on the assessment, develop a tailored maintenance strategy that outlines the frequency and types of maintenance tasks required for different cable sections.

Routine Inspections
Perform regular visual inspections to identify any visible signs of cable damage, wear, or deterioration. Inspect cable supports, terminations, and joint boxes.

Cable Testing
Conduct periodic insulation resistance tests, partial discharge tests, and other diagnostic tests to assess cable health and identify potential weaknesses.

Cleaning and Protection
Clean cable surfaces to prevent the buildup of contaminants that can lead to electrical leakage. Apply protective coatings or insulation materials where needed.

Joint and Termination Checks
Inspect cable joints and terminations for signs of heat, corrosion, or mechanical stress. Tighten connections and address any issues promptly.

Repairs and Replacements
In case of cable damage or deterioration, conduct necessary repairs or replacements following industry best practices and standards.
