In a world of 24/7 uptime expectations, high-density data centers, and electrified commercial buildings, the real question for wire and cable manufacturers isn’t “Should we promote thermal imaging?” – it’s “Can we afford not to?”

1. What Thermal Imaging Actually Reveals in Wire & Cable Systems

Thermal imaging (infrared thermography) gives facility owners and electrical professionals a non-contact, visual way to see I²R losses and abnormal heating in conductors, terminations, and bus systems. For wire and cable manufacturers such as Prysmian and Encore Wire, that view is invaluable because it focuses attention exactly where performance, safety, and brand reputation intersect.

Every energized conductor generates some heat. The danger appears when you see localized temperature rise caused by:

• Loose or improperly torqued terminations – lugs, set-screws, bolted joints, and breaker stabs.
• Overloaded conductors – circuits and feeders pushed beyond practical ampacity, especially in hot or congested areas.
• Unbalanced phases – one phase runs significantly hotter due to load imbalance, accelerating insulation aging on that leg.
• Undersized or misapplied cable types – conductors not properly derated for ambient temperature, bundling, or installation conditions.
• High-resistance splices and taps – poor crimps, compromised connectors, or transition points between cable types.
• Mechanical or thermal damage along a cable run – crushed, kinked, or stressed spots that show up as abnormal heating.

These problems often have nothing to do with the quality of Prysmian or Encore Wire cable itself. Yet when a hot termination fails, the brand stamped on the insulation is usually the first name mentioned. By encouraging customers to adopt thermal imaging, manufacturers help ensure that installation quality and loading conditions are properly evaluated – before their products are unfairly blamed for failures.

2. Why Data Centers & Large Commercial Facilities Depend on Thermography

Data centers, hospitals, high-rise towers, and mission-critical commercial buildings share a few key characteristics:

• Continuous, 24/7 loads with limited downtime windows.
• High power density in riser spaces, cable trays, UPS rooms, and power distribution units (PDUs).
• Massive quantities of conductors and terminations – miles of cable, thousands of connection points, and complex redundancy.

2.1 Detecting problems long before failure

In these environments, thermal imaging becomes a cornerstone of a condition-based maintenance strategy. Using a properly configured thermal camera, technicians can:

• Verify that critical feeders and bus connections are operating within acceptable temperature rise across all three phases.
• Identify overheated PDUs, panels, and breakers before nuisance tripping, insulation breakdown, or arc-flash hazards occur.
• Catch neutral and grounding issues caused by harmonics and non-linear loads common in IT and office environments.
• Reveal overfilled conduits or cable trays where ventilation and heat dissipation are compromised.

2.2 Downtime and brand risk

When a single overheated connection knocks out a row of servers or a critical mechanical system, the true cost isn’t just a damaged lug or a burned conductor. It’s:

• Unplanned downtime and revenue loss.
• Emergency repair costs at premium labor rates.
• Potential fire and arc-flash hazards in crowded electrical rooms.
• Damage to the cable manufacturer’s reputation, even if the root cause is installation-related.

By championing thermal imaging as a best practice for every data center and large commercial project using their products, wire and cable manufacturers protect both the facility and their own name. It signals that Prysmian, Encore Wire, and similar companies are committed to verifiable long-term performance, not just initial installation.

3. The Role of Certified Thermal Electricians™

A thermal camera by itself is not a guarantee of good data. The difference between a meaningless picture and a diagnostic thermogram is the skill of the person behind the lens. That’s where Certified Thermal Electricians™ come in.

A Certified Thermal Electrician brings three essential elements together:

3.1 Electrical expertise

• Understanding of ampacity, derating, and installation methods for different cable constructions and raceways.
• Hands-on knowledge of torqueing practices, terminations, cable tray design, and overcurrent protection.
• Familiarity with code requirements and manufacturer installation instructions for wire and cable systems.

3.2 Thermography skills

• Correct camera setup: focus, temperature range, emissivity, and reflections.
• Ensuring circuits are at meaningful load levels so that I²R heating can be properly assessed.
• Interpreting patterns: distinguishing between phase imbalance, loose terminations, undersized conductors, and environmental influences.

3.3 Condition-based maintenance mindset

• Planning routine surveys for high-risk, high-value equipment.
• Categorizing anomalies by risk level so that the most critical hot spots are corrected first.
• Generating clear reports with images, temperature data, and corrective recommendations.

When wire and cable manufacturers publicly recommend Certified Thermal Electricians™ as preferred partners, they help ensure that thermal imaging is applied correctly and consistently. That means fewer misdiagnosed “cable failures” and more documented evidence that their products are performing exactly as designed.

4. Strategic Benefits to Wire & Cable Manufacturers

4.1 Fewer warranty disputes and misattributed failures

Many supposed “cable failures” are ultimately traced back to installation defects, overloads, or poor terminations. When end-users adopt thermal imaging as a routine maintenance practice, these issues are:

• Detected early, before catastrophic failure.
• Documented with time-stamped thermal images.
• Corrected in a controlled, scheduled manner.

This gives manufacturers like Prysmian and Encore Wire a more accurate picture of how their cables behave in the field and reduces the likelihood that product quality is blamed for problems caused by installation, loading, or maintenance.

4.2 Differentiated technical support and communication

By publishing clear, educational content around thermal imaging and wire/cable performance, manufacturers can:

• Position their brand as a technical authority on thermal performance, not just a commodity copper supplier.
• Give engineers and facility managers practical thermography checklists and guidelines tied directly to their cable products.
• Provide sales and support teams with concrete examples that explain why a cable issue is truly thermal, mechanical, or installation-related.

4.3 Alignment with modern safety and reliability programs

Electrical safety programs, risk managers, and insurers increasingly expect to see documented thermographic surveys as part of preventive maintenance. When wire and cable manufacturers actively promote and support thermal imaging:

• They demonstrate alignment with best-practice maintenance strategies and reliability programs.
• They help customers reduce the risk of arc-flash events, fires, and unexpected outages.
• They reinforce the message that their conductors are meant to be part of a monitored, managed system – not “install it and forget it” components.

4.4 Stronger positioning in the energy and digital transition

As buildings and campuses become more electrified and digitized, cable systems face:

• Higher power densities and tighter spaces.
• Hotter ambient conditions in risers and equipment rooms.
• Non-linear loads, harmonics, and constantly shifting demand.

Manufacturers who talk openly about temperature rise, thermal limits, and ongoing thermography are telling the market: “We understand how our products live in the real world – and we are invested in their performance for decades, not just at install.”
