Cable Anchorage Pull Force And Torque Tester For EV Charging
Stations IEC 61851-23
Product information: It is designed and manufactured according to IEC 61851-23:2023 clause 11.6.102 and Figure 110, Figure 111 and Table 114. Sample scope, purpose, principle, structure and use environment | Samples and restrictions | Electric vehicle AC and DC charging station | Test purpose | The flexible cord anchorage of the appliance shall relieve
conductors at the terminals from pulling force and torque. This
device is used to test the ability of the cord anchorage or cable
fixing device of EV AC/DC charging stations to withstand specified
tensile force and torque. | Test Principle | The pulling force is realized by using a motor to drive an
eccentric wheel mechanism. The motor speed is adjustable to ensure
that the pulling force is applied accurately each time. It is
equipped with a monitoring function for the pulling force duration.
Torque is applied by a motor-driven tray that lifts a weight; When
the time is reached, the tray automatically resets the lifting
weight and ends the application of torque. | Structure and characteristics | The equipment adopts PLC control and motor drive. The weights apply
stable pulling force, and torque is generated through the
combination of weights and a torque arm. The system allows setting
the number of pulling force applications and the torque test duration. Once the
preset number of cycles or duration is reached, the equipment stops
automatically. After the test, the maximum allowable displacement
of the EV charging connector cable must not exceed the specified
limit in the standard. This equipment is compatible with charging
station samples fitted with charging guns of different cable
lengths. | | | Usage Environment | Power supply: AC220V±10%/50-60Hz, 1KW; working temperature 0-40℃,
humidity 30%-90%; Dimensions: about W4000*D600*H1850mm; weight: about 300kg |

500 to 1200 mm (i.e., the cable outlet position), allowing it to
meet the testing requirements of charging stations with different
cable outlet positions. |
