High Voltage Flexible Cable Testing Equipment Flexing Tester AC 380V / 50HZ
This cable tester is designed and manufactured in accordance with the standard requirement of IEC60245.2 clause 22.7. 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.
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.
