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.
