Power Cord Flexing and Strain Relief Test Equipment for Appliance Safety Laboratories
Power cords and internal wiring in appliances, cleaning equipment, medical devices and laboratory instruments may experience repeated bending, pulling, twisting and movement. If the cord anchorage or internal wiring route is poorly designed, wire breakage, insulation damage or leakage risk may occur.
Common test items
Typical tests include power cord flexing, cord anchorage pull, torsion, strain relief, internal wiring flexing and moving-part cable fatigue. Test angle, speed, force, cycle count and pass-fail criteria should be defined by the applicable standard and product construction.
Equipment features
- Adjustable bending angle, speed and cycle count;
- Fixtures for different cord diameters and product outlets;
- Electrical continuity monitoring with automatic stop;
- Force, torque, displacement and cycle data recording;
- Protective cover, emergency stop and overload protection.
Why custom fixtures are important
The outlet position, bending center, cord diameter, strain relief and operating posture vary by product. Custom fixtures help reproduce the real working condition and improve repeatability, especially for appliances, medical devices and non-standard wiring harnesses.
LSKFT test systems
LSKFT provides power cord flexing testers, strain relief pull testers, torsion testers, internal wiring bending devices and customized wiring fatigue systems for product development and quality inspection.
