IEC60245-2 Figure 1 Flexible Cables Flexing Tester Cable Testing Equipment
Standard:IEC60245-1 Rubber insulated cables-Rated voltages up to and including 450/750 V-Part 1:General requirements,IEC60245-2 clause 3.1 Figure 1 Rubber insulated cables-Rated voltages up to and including 450/750 V-Part 2: Test methods.
Application:It is used for checking mechanical strength of completed flexible cables. This test does not apply to flexible cables with cores of nominal cross-sectional area greater than 4mm2 and cables having more than 18 cores laid up in more than two concentric layers.
Test sample:Completed flexible cables.
Feature:This cable tester consists of a carrier C (see IEC60245-2 Figure 1),a driving system for the carrier and four pulleys for each sample of cable to be tested. The carrier C supports two pulleys A and B, which are of the same diameter. The two fixed pulleys, at either end of the apparatus, may be of a different diameter from pulleys A and B, but all four pulleys shall be so arranged that the sample is horizontal between them. The carrier makes cycles (forward and backward movements) over a distance of 1 m at an approximately constant speed of 0,33m/s between each reversal of the direction of movement. A sample of flexible cable about 5 m long shall be stretched over the pulleys, each end being loaded with a weight. The mass of this weight and the diameter of pulleys A and B are given in following table.
