Quality is built in, not just inspected. Our production line features real-time monitoring:

• Online Laser Diameter Control: Continuous monitoring of insulation and sheath thickness to ensure perfect concentricity.
• Spark Testing: 100% online high-voltage spark testing during extrusion to detect any microscopic pinholes or defects in the insulation.

Before leaving our facility, every batch undergoes mandatory Factory Acceptance Testing (FAT):

• Conductor Resistance Test: Ensures high-purity copper/aluminum is used and checks for optimal conductivity to prevent overheating.
• Insulation Resistance Test: Verifies the integrity of the insulating material to prevent leakage and short circuits.
• High-Voltage Withstand Test (AC/DC): Subjecting the cable to voltages significantly higher than its rating to ensure the insulation can handle electrical surges.
• Partial Discharge Test (for MV/HV Cables): Utilizing advanced sensors to detect internal micro-voids, ensuring long-term operational stability for high-voltage networks.

We simulate real-world stress to ensure structural integrity:

• Tensile Strength & Elongation: Testing the durability of the sheath and insulation before and after accelerated aging.
• Hot Set Test: Crucial for XLPE cables to verify cross-linking density and heat resistance.
• Bending & Abrasion Resistance: Confirming the cable remains functional under mechanical strain or repetitive movement.

For specialized projects, we conduct rigorous safety compliance tests:

• Flame Retardancy & Fire Resistance: Testing the cable’s ability to prevent the spread of fire or maintain circuit integrity during a blaze.
• Smoke Density & Halogen Acid Gas Emission: Ensuring minimal toxic emissions for cables used in public spaces (LSZH).

Every shipment is accompanied by a Full Factory Test Report and a Certificate of Compliance, providing our clients with total transparency and peace of mind.
