Power Cord Strain And Twist Tester 

Product details: Model ZLT-LN1

To determine the strain and twisting of the supply cord where it enters the appliance, in accordance with IEC60335-1 clause 25.15, IEC 60950-1 clause 3.2.6, IEC60601-1 clause 8.11.3.5,and IEC 60065.

Appliances provided with a supply cord, and appliances intended to be permanently connected to fixed wiring by a flexible cord, 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 1s in the most unfavorable 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.  

Standard Outfit:
1 set of pull weights, 20N*2-30N*2, for strain 30 N-40N -60 N-100 N,
1 set of torque weights, 2.86N-7.14N-10N, for torques 0.1Nm-0.25Nm-0.35Nm,
1 speed fixed system, 1 times/s tension frequency, 
1 control unit with 4 digit (0-9999) predetermining counter to switch off the drive, and records the number of tension times and torque time,
Power Supply: A.C.220V 50Hz, other voltages and frequencies on request.
