Electrical cables are also assets: the importance of managing their lifecycle

When an organization thinks about critical assets within its electrical system, it usually focuses on transformers, motors, inverters, or substations. However, there is one component that frequently goes unnoticed until a failure occurs: electrical cables.

Although they remain out of sight for much of their useful life, cables are responsible for transmitting the energy that keeps industrial processes, generation systems, critical infrastructure, and commercial operations running. Their performance directly impacts the reliability, safety, and operational continuity of any facility.

For this reason, cables should not be considered merely as an infrastructure component, but as an asset that requires management throughout its entire lifecycle.

The mistake of waiting for a failure to occur

In many organizations, there is still a perception that a cable is in good condition as long as it continues to operate. However, experience shows that failures rarely occur suddenly.

Factors such as insulation aging, thermal stress, moisture, partial discharges, overloads, installation defects, and environmental conditions can progressively deteriorate the cable's condition without producing obvious symptoms.

When the failure finally happens, the consequences are usually much more costly than a preventive diagnostic strategy:

• Production interruptions.

• Financial losses due to unavailability.

• Emergency repair costs.

• Safety risks for personnel.

• Negative impact on reliability indicators.

The question should no longer be if a cable will fail, but when it will do so and what information we have to anticipate it.

Asset management: moving from reacting to anticipating

Modern asset management aims for decisions to be based not on the age of the asset or subjective perceptions, but on reliable technical information about its actual condition.

In the case of electrical cables, this involves implementing assessment strategies that allow answering fundamental questions:

• What is the current state of the insulation?

• Are there early signs of deterioration?

• What level of risk does the asset present?

• Does it need to be replaced, or can it continue operating safely?

• What is the best investment to maximize its useful life?

Answering these questions allows for optimizing resources, reducing risks, and making data-driven decisions.

The value of knowing a cable's condition

Today, there are advanced technologies that allow the condition of wiring systems to be assessed without waiting for a failure to occur.

Diagnostic testing provides valuable information about insulation condition, the presence of defects, and the aging level of the asset.

This information enables:

• Prioritizing investments.

• Planning maintenance.

• Reducing unexpected failures.

• Extending the useful life of assets.

• Improving the reliability of the electrical system.

In other words, they allow transforming corrective maintenance into a risk-based management strategy.

A strategic asset for operational continuity

Every installed cable represents a significant investment for the organization. However, the true value lies not only in its acquisition but in its ability to operate reliably for years.

Companies that properly manage their electrical assets understand that reliability does not depend on luck, but on knowing the actual condition of their systems.

Therefore, periodic cable assessment must be part of any serious asset management strategy, especially in sectors where operational continuity is critical, such as manufacturing, power generation, transmission, distribution, and renewable energy.

Conclusion

Electrical cables have a lifecycle. The difference lies in how they are managed.

Waiting for a failure to reveal a problem is usually the most expensive alternative. Instead, knowing the actual condition of the assets enables timely decision-making, resource optimization, and the maximization of electrical system reliability.

Asset management begins when we stop viewing cables as simple conductors and start understanding them as strategic elements for the continuity and performance of our operations.
