| Tightening force for leadings and cables |
|
|
|
| |
The tightening force is the identified value to pull out a leading or cable
out of the crimped connector. The values deliver information about the
mechanical stress of crimping connections. In dependence of the different
cable lugs and connectors we have different regulations about the
minimum tightening forces for crimping connections.
To pass the test acc. to the different norms and regulations it is necessary
that the electrical conductor cannot pulled out inside of 60 seconds
when testing with 100 % of the tightening force.
Following a summary
of such values under consideration of the different norms.
