Product Overview
The ZLT-QL3 Flexible Cables Kink Test Apparatus is a comprehensive testing solution designed to assess the mechanical strength of two-core and three-core sheathed flexible cords. It complies with IEC 60245-2 Clause 3.6 (Figure 7)—the global standard for evaluating how cords withstand repeated kinking (a common cause of wire breakage or insulation damage).
This apparatus supports cords with a conductor cross-sectional area of up to 1.5mm² and operates at a test speed of 9 complete cycles per minute (with a travel distance of 650mm per up/down movement). Key features include a PLC control system (for automated, consistent testing), a built-in test current circuit (supports 6A, 10A, 16A), and a set of calibrated weights (50N, 70N, 100N) to apply load during testing. The power supply is standard A.C. 220V 50Hz, with custom voltages/frequencies available on request. Manufactured by ZLTJC, the ZLT-QL3 is trusted by cable manufacturers, automotive suppliers, and QA labs to ensure cords meet durability requirements for industrial, household, and automotive applications.

Product Features
Automated PLC Control System
The integrated PLC control system eliminates manual operation errors by automating test speed (9 cycles/min) and travel distance (650mm). This ensures every test is consistent, even with long testing sessions.
Versatile Test Current Support
The built-in circuit supports 6A, 10A, and 16A—covering the current ratings of most flexible cords used in household appliances, power tools, and automotive wiring. This allows testing under real-world current loads.
Calibrated Weight Set
The included 50N, 70N, and 100N weights apply precise loads during kink testing, matching the requirements of IEC 60245-2 Clause 3.6. The weights are calibrated for accuracy, ensuring reliable results.
Customizable Power Options
While the standard power supply is A.C. 220V 50Hz, custom voltages (e.g., 110V) and frequencies (e.g., 60Hz) are available—making the apparatus suitable for labs in North America, Europe, and Asia.
Durable Test Structure
The fixed clamps and anti-torsion guidance system prevent cord slippage during testing, while the robust frame resists vibration. This durability ensures the apparatus maintains accuracy over thousands of test cycles.
Application
Flexible Cable Manufacturing
Cable producers use the ZLT-QL3 to test two-core and three-core sheathed cords (up to 1.5mm²) before shipping, ensuring they withstand kinking in daily use (e.g., vacuum cleaner cords, extension cables).
Automotive Industry
Tests wiring harnesses and flexible cords used in vehicles (e.g., dashboard wiring, seat controls) to validate durability against vibration and kinking—meeting automotive safety standards.
Household Appliance Production
Appliance manufacturers (e.g., washing machines, refrigerators) test power cords to ensure they do not fail due to repeated bending or kinking, preventing electrical hazards.
Industrial Equipment Testing
Used for cords in power tools (e.g., drills, grinders) and industrial machinery, where kinking is common. The apparatus ensures cords maintain electrical continuity and mechanical strength under stress.
FAQ
Q: What is the test speed of the ZLT-QL3?
A: The standard test speed is 9 complete cycles per minute, with each up/down movement covering 650mm—this aligns with IEC 60245-2 Clause 3.6.
Q: Can the apparatus test cords with a cross-sectional area larger than 1.5mm²?
A: No. The ZLT-QL3 is optimized for cords with a maximum conductor cross-sectional area of 1.5mm², which covers most standard flexible cords for household and light industrial use.
Q: What power supply options are available?
A: The standard power supply is A.C. 220V 50Hz, but we offer custom voltages (e.g., 110V) and frequencies (e.g., 60Hz) on request to match regional electrical standards.
Q: What is the lead time for the ZLT-QL3?
A: The lead time is 20 days from order confirmation. This accounts for the precision calibration of components (e.g., weights, PLC system) to ensure compliance with IEC 60245-2.
Q: Does the apparatus include a test current circuit?
A: Yes. It comes with a built-in test current circuit that supports 6A, 10A, and 16A, allowing you to test cords under real-world current conditions without additional equipment.
