PV Module Cables torsion testing equipment/twisting force testing machine/torque force testing apparatus

PV Module Cables torsion testing equipment/twisting force testing machine/torque force testing apparatus

Testing standard

It's conform IEC61730-2:2016 testing standard 

Purpose

It’s to determine that the terminations, the attachment of the terminations, and the attachment of the cables to the body of the module will withstand stresses that are likely to be applied during normal assembly or handling operations, test in 4.14.2 (MQT14.1) and test in 4.14.3 (MQT 14.2) are to be performed

The Main Technical Sepcifications 

Testing procedure

1. After the pull test the specimen shall be mounted in the test apparatus for torque test

2. The unloaded cable shall be marked so that any torsion relative to the gland can be easily detected, and then a  torque shall be applied for 1min

3.During the test, the twist or torsion inside the cable gland or other cord anchorage shall not exceed 45°, the cable shall be held in position by the cord anchorage
