IEC 60245-2 Integrated Two Pulleys and Three Pulley Flexing Test Machine Cable Bending Tester

IEC 60245-2 Integrated Two Pulleys and Three Pulley Flexing Test Machine Cable Bending Tester

Product Infromation

The SN2302B Integrated Two Pulleys and Three Pulley Flexing Test Machine is a precision testing system designed to evaluate the bending mechanical performance of flexible finished cables.
It supports both two-pulley and three-pulley flexing tests, providing a versatile platform for verifying cable durability under repeated mechanical stress.
This equipment complies with multiple international standards, ensuring reliable testing results recognized by certification bodies such as TÜV, VDE, and UL.

Applicable Standards

IEC 60245-1:2008, Clause 5.6.3.1

IEC 60245-2:1998, Clause 3.1 & Figure 1; Clause 3.5 & Figure 6

IEC 60227-1, Clause 6.6.3.2 (IEC 63294:2021, Clause 6.6)

IEC 60227-2, Clause 3.1 & Figure 1

Applications

This flexing tester is suitable for finished flexible cables, including high-flex cables, power cords, and control cables.
It is particularly applicable for manufacturers and laboratories performing TÜV, VDE, UL, and IEC compliance tests.
Not applicable to cables with more than two concentric layers or those exceeding 18 conductors.

Test Principle

A 5-meter cable specimen is repeatedly flexed over a 1-meter stroke through either two or three pulleys.
By switching between pulley configurations and adjusting motion speed, users can perform both two-pulley and three-pulley bending tests to assess the endurance and electrical stability of cable samples.
