Metallic Power Cord Tension Torque Tester Electrical Cable Pull Twist Testing Equipment IEC60335-1:

Metallic Power Cord Tension Torque Tester Electrical Cable Pull Twist Testing Equipment?

Product information:

The power cord tension & torque test?appliance is designed and manufactured accordingto IEC60335-1:25.15.

The test equipment is mainly?applied for testing the power cord tension and torque at the terminal two trials of the appliances which are with a power cord, and intended flexible cord permanently connected to the fixed wiring and other household electrical appliances, medical equipment, checking whether the clamping device is secure.

Main technical parameters:

Reference ?– Pull force and torque:

Test Principles:

Electric appliances is provided with a supply cord, and electric appliances is intended to be permanently connected to fixed wiring by a flexible cord, there shall have a cord anchorage. The cord anchorage shall relieve conductors from strain, including twisting, at the terminals and protect the insulation of the conductors from abrasion.

A mark is made on the cord while it is subjected to the pull force shown in follow table, at a distance of approximately 20 mm from the cord anchorage or other suitable point.

The cord is then pulled, without jerking, for 1 s in the most unfavourable direction with the force specified. The test is carried out 25 times.

The cord, unless on an automatic cord reel, is then subjected to a torque that is applied as close as possible to the appliance. The torque is specified in following table and is applied for 1 min.

During the tests, the cord shall not be damaged and shall show no appreciable strain at the terminals. The pull force is reapplied and the cord shall not be longitudinally displaced by more than 2 mm.
