Whether newly installed or in-service, our testing helps verify performance, uncover hidden defects, and extend the life of your cable systems. Independent Testing Company is a medium voltage cable testing company.

The Importance of Cable Testing

Medium voltage cables are a critical component of your facility’s electrical distribution system. While they are designed for long service life and high reliability, they are not immune to:

• Deterioration due to age or environmental conditions
• Installation defects
• Mechanical damage
• Moisture ingress or insulation breakdown

Left unchecked, these issues can lead to unexpected outages and complete system failure.

Our Testing Capabilities

We offer both withstand testing and diagnostic testing to evaluate the condition of your cables and ensure safe, continued operation.

Withstand Testing

Withstand tests apply higher-than-normal voltages to the cable system to intentionally stress the insulation. This type of testing helps reveal:

• Severe insulation defects
• Degraded splices or terminations
• Fault-prone areas are likely to fail under load

This test is typically used during acceptance testing or after major repairs to confirm system integrity.

Diagnostic Testing

Diagnostic tests gather quantitative data about the cable’s condition without stressing the insulation to the point of failure. These non-destructive methods provide:

• Trending data over time
• Early warning of degradation
• Informed decision-making for maintenance planning

Common diagnostic methods include:

• Tan Delta Testing
• Partial Discharge Testing
• Time Domain Reflectometry (TDR)

Additional Services:

• Medium Voltage Cable Splicing & Termination
• Visual & Infrared Inspection
• Location & Identification of Underground Faults
• Cable Jacket Testing & Moisture Detection
