When solar projects are designed for 30 years or more, every component must be proven reliable — especially the solar cables that connect the entire system.
At KUKA CABLE, quality assurance goes beyond certificates. Our in-house ISO/IEC 17025-accredited laboratory transforms compliance into measurable, repeatable reliability.
What Is an ISO/IEC 17025 Laboratory?
ISO/IEC 17025 is the international standard that defines the competence requirements for testing and calibration laboratories.
A lab accredited to this standard demonstrates:
Technical competence and qualified personnel
Calibrated and validated test equipment
Reliable measurement methods with documented uncertainty
A complete quality management system with traceability
In short, an ISO/IEC 17025 laboratory ensures that every test result is accurate, traceable, and globally recognized — providing confidence for customers, EPCs, and investors.
KUKA CABLE’s ISO/IEC 17025 Laboratory: The Core of Our Quality System
KUKA CABLE operates an independent ISO/IEC 17025-accredited laboratory, fully integrated into our production and quality management system.
Here’s how it works across each stage of cable manufacturing:
1. Raw Material Verification
Every batch of copper, polymer, and additive is tested before production begins.
We measure parameters such as conductivity, tensile strength, ash content, and polymer melt flow index to ensure only qualified materials enter the production line.
2. In-Process Quality Monitoring
During manufacturing, inline sensors continuously track concentricity, insulation thickness, and conductor resistance.
Our lab verifies these readings daily, ensuring stable performance across all production lines.
3. Type and Batch Testing
Each production batch undergoes multiple lab tests, including:
Tensile and elongation performance
Dielectric strength and insulation resistance
Partial discharge and spark testing
Accelerated aging (UV, thermal, humidity)
All tests follow IEC and EN standards, validated under ISO/IEC 17025 procedures.
4. Accelerated Aging and Life Simulation
We simulate decades of outdoor exposure within controlled chambers using UV, thermal, and humidity cycles.
This allows us to predict long-term reliability and ensure our solar cables can withstand harsh field conditions.
5. Calibration and Traceability
Every measurement instrument in the lab is regularly calibrated to national and international standards.
This ensures test results are consistent and comparable across global labs.
Why ISO/IEC 17025 Testing Matters for Solar Projects
An accredited laboratory does more than verify compliance — it directly affects project success:
Improved Reliability: Prevents batch variation and reduces field failure risk.
Better Bankability: Provides auditable data for financing and due diligence.
Faster Troubleshooting: Enables root-cause analysis through retained samples and traceable reports.
Lower Project Risk: EPCs and investors gain confidence from transparent testing documentation.
For global PV developers and EPC contractors, choosing a supplier with an ISO/IEC 17025 lab is not just a quality decision — it’s a financial safeguard.
Integrated with the KUKA SIF Quality System
The ISO/IEC 17025 lab is a central part of our SIF (Safety–Integrity–Fidelity) system:
Safety: Ensures every solar cable meets fire and electrical standards.
Integrity: Links real-time production monitoring to lab validation.
Fidelity: Retains test samples for long-term stability tracking.
This closed-loop process means every KUKA solar cable is traceable from raw material to finished reel, ensuring reliability from factory to field.
What to Look for in a Cable Supplier’s Lab
When evaluating a solar cable manufacturer, you can ask:
Is the laboratory ISO/IEC 17025 accredited, and what is its scope?
Are batch-level tests performed, not just type-approval tests?
Are calibration certificates traceable and up to date?
Does the lab keep retained samples for long-term verification?
If a manufacturer cannot provide this information transparently, it’s a clear warning sign of quality inconsistency.
From Certification to Confidence
A certificate proves compliance.
An ISO/IEC 17025-accredited laboratory — like the one operated by KUKA CABLE — proves control, traceability, and trust.
Through continuous testing, calibration, and quality improvement, KUKA CABLE ensures that every meter of solar cable performs reliably for decades — delivering safety, stability, and true peace of mind for solar power projects worldwide.
