Apparatus for testing cord retention CR-1
Product details:
This device conforms to the standard requirement of IEC60884 figure 20. It is for testing cord retention is for check the effectiveness of the retention of the cable of the cord anchorage.
The cord anchorage is used in the normal way, clamping screws, if any, being tightened with a torque equal to two-thirds of that specified in standard. After reassembly of the specimen, the component parts shall fit snugly and it shall not be possible to push the flexible cable into the specimen to any appreciable extent. The specimen is placed in the test apparatus so that the axis of the flexible cable is vertical where it enters the specimen.
The according tensile force of the flexible cable:
| The rated current of the flexible cable(A) | The rated voltage of the flexible cable(V) | The tensile force |
| 2.5 | — | 50 |
| 2.5～16 | <250 | 60 |
| 2.5～16 | >250 | 80 |
| >16 | — | 100 |
Technical parameters:
Power Supply: 220V 50Hz or 115V 60Hz
Number of testing: 1~9999( it is adjustable. 100 is by default.
Rate of testing: 60 times/min
Weight: 10N*1, 60N*1, 20N*2
Conforms to standard: IEC60884Figure 20, VDE0620
