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.
