Power Cord Strain and Twist Tester (Model ZLT-LN1)

This precision equipment is designed to determine the strain and twisting resistance of supply cords at the point of entry into an appliance, strictly following IEC60335-1 clause 25.15 standards.

• Purpose: Ensures cord anchorages relieve conductors from strain and twisting at terminals.
• Testing Procedure: Pull tests are conducted 25 times for 1 second in the most unfavourable direction without jerking.
• Torque Application: Torque is applied as close as possible to the appliance for 1 minute.
• Safety Assurance: Protects conductor insulation from abrasion and prevents longitudinal displacement exceeding 2 mm.

Standard Outfit Includes:

• 1 set of torque weights (2N-5N-7N) for torques 0.1Nm-0.35Nm.
• 1 set of pull weights (20N*2-30N*2) for strain 30N-100N.
• 1 fixed speed system with 1 times/s tension frequency.
• 1 control unit with a 4-digit predetermining counter for automatic drive shut-off and data recording.
