Cord Grip (Anchorage Tester) For Electrical Lab Training.
Cord Grip (Anchorage Tester) - For Electrical Lab Training
The effectiveness of the cord grip (anchorage) of an electrical or
electronic appliance is determined by subjecting the cord to a specified
pulling force for a specified number of times. Immediately afterwards,
the cord is subjected to a specified torque. The action of these two
forces shall not cause the cord to get shifted in the cord grip and the
conductors in the terminals by more than a specified distance.
The Cord Grip (Anchorage) Tester
consists of an arrangement to apply the specified pulling force, and an
arrangement to apply the specified torque, on the cord of the appliance
under test.
The arrangement to apply the pulling force
consists of a dead weight suspended from two threads, which, when free,
acts on the cord fixed to the appliance under test through a grip in
which one end of the cord is rigidly held. A lever is provided to apply
and release the pull on the cord. A stroke counter records the number at
pulling operations undergone by the cord.
