Lead Terminal Strength Tester
Application
This tester is widely applied in:
PV Module Lead Terminal Tensile and Torsion Testing: Assess the mechanical strength of lead terminals under controlled force.
Junction Box and Lead Terminal Reliability Evaluation: Verify the adhesion and structural integrity during transport and installation.
R&D Material and Structure Optimization: Validate design improvements in lead terminal materials and mounting structures.
Production Quality Control: Conduct batch inspection and ensure compliance with mechanical strength requirements.
IEC 61215-2 Standard Certification Testing: Confirm lead terminal performance under certified testing protocols.
Installation and Transport Safety Verification: Simulate real-world mechanical stresses to prevent failure.
Standards
IEC 61215-2:2016 – Photovoltaic (PV) Module Design and Certification Standard
