UL 6073-2021 Clause 9.4 PV Connector Cyclic Tensile Testing Machine For Durability Testing
The PV Connector Cyclic Tensile Testing Machine fully complies with UL6073-2021 (Clause 9.4) for Connectors Used in Photovoltaic Systems. It is designed for PV connectors with cables up to 250AWG. Adopting PLC intelligent control and servo motor drive, it performs reciprocating tensile cycles under load current to detect breakage, wire disconnection, and validate mechanical and electrical reliability. It is essential for R&D, quality inspection, and mass production testing of PV connectors.
