Standard:
IEC60245-1 Rubber insulated cables-Rated voltages up to and including 450/750 V-Part 1:General requirements, IEC60245-2 clause 3.3 and Figure 3 Rubber insulated cables-Rated voltages up to and including 450/750 V-Part 2: Test methods.
Application:
The electric wire abrasion test apparatus is used for measuring the wear resistance of completed flexible cables.
Test sample:
Completed flexible cables.
Parameters:
| Power supply | AC220V 50Hz |
| Fixed shaft diameter | Φ40±0.3mm |
| Test rate | Single strokes 40±1 times/minute |
| Test stroke | 0.1mm up-and-down movement |
| Working station | 3 |
| Weight | 500±5g*3 |
| Counter | 0~999999 (can be preset) |
| Dimension | 1200×400×1400 (mm) |
Feature:
This testing is performed on three pairs of samples of flexible cable, each sample having a length of about 1 m. In each pair one sample shall be wound so as to give nearly two turns on a fixed reel having a diameter of 40 mm at the bottom of the groove as shown in figure 3, the distance between the flanges of the reel being such that the turns are in close contact with each other. The sample shall then be fixed to prevent any movement relative to the reel. The other sample shall be placed in the groove formed by the turns and a weight having a mass of 500 g shall be attached to one end. The other end shall be moved up and down over a distance of 0.10 m, at a rate of about 40 single strokes per minute.
