Ensuring Reliability in Power Networks: 66kV Outdoor Termination Partial Discharge Testing at COMPAQ International 

In today’s rapidly evolving power sector, reliability is more than a goal — it is a necessity. High-voltage (HV) cable systems form the backbone of transmission and distribution networks, and their accessories play a crucial role in ensuring long-term stability. Among these, 66kV outdoor terminations are critical components, designed to withstand harsh environments while maintaining consistent performance. 

At COMPAQ International, we understand that designing world-class products is only the beginning. True reliability is proven in the laboratory — where every termination, joint, and accessory is put through rigorous testing under the most demanding conditions.

 What Is Partial Discharge (PD) Testing and Why It Matters?

Partial Discharge (PD) testing is one of the most important diagnostic tools for assessing the quality and reliability of high-voltage accessories. PDs are localized dielectric breakdowns that occur in voids, gaps, or imperfections within insulation systems. While small, they are early indicators of potential insulation failure.

A termination that passes PD testing ensures:

• Longer service life by eliminating hidden weak points.
• Operational safety for utilities, contractors, and end users.
• Network reliability even under continuous electrical and environmental stress. 

By investing in in-house PD testing facilities, COMPAQ provides utilities with the confidence that every product has been validated for long-term performance before it reaches the field. 

Inside COMPAQ’s High-Voltage Laboratory

Our state-of-the-art HV Laboratory is equipped to simulate real-world operating conditions for voltages up to 66kV and beyond. The featured image shows one of our 66kV outdoor terminations undergoing PD testing — a critical step in our quality validation process. 

Key capabilities of the COMPAQ HV Lab include:

• Partial Discharge measurement with high sensitivity.
• AC/DC withstand testing for medium- and high-voltage cable systems.
• Environmental stress simulations including humidity and contamination conditions.
• HV Impulse testing 

This facility is not just a laboratory — it is the foundation of our commitment to reliability, safety, and trust.

 Why COMPAQ’s Approach Stands Out

Many manufacturers rely on external testing to validate performance. At COMPAQ, we believe in going further:

• End-to-End Control: From design to material selection to in-house testing.
• Global Standards Compliance: Every product is tested to international benchmarks.
• Customer Assurance: Utilities, EPC contractors, and installers can rely on proven performance rather than assumptions.
• Continuous Improvement: Data from PD and type testing directly feeds into R&D, making our next generation of products even more robust.

 This holistic approach ensures that our products are not only fit for today’s networks but also for the evolving challenges of tomorrow. 

Reliability in Every Connection

With utilities worldwide moving toward underground cabling, renewable integration, and grid modernization, the importance of tested and proven accessories cannot be overstated. A single failure in a termination can result in costly outages, reputational risks, and operational delays. 

That is why at COMPAQ International, we uphold a simple principle: “Reliability isn’t designed on paper. It is tested, proven, and delivered”. 

The 66kV outdoor termination PD testing at COMPAQ’s HV Laboratory represents more than a technical milestone — it reflects our unwavering focus on quality, safety, and trust. By combining advanced testing capabilities with decades of expertise, COMPAQ ensures that every product meets the highest standards of reliability. 

As the world accelerates toward sustainable and resilient power networks, COMPAQ remains committed to delivering tested assurance in every connection.
