Test Stroke 1000m Flexible Cable Testing Equipment, 0-400V Voltage loading
Standard description:
This test shall be carried out by means of the apparatus shown in
figure 1 . This apparatus consists of a carrier C, 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 0,33 m/s between each reversal of the direction of
movement. Cable Testing Equipment
The pulleys shall be made of metal and have a semi-circular shaped
groove for circular cables and a flat groove for flat cables. The
restraining clamps D shall be fixed so that the pull is always
applied by the weight from which the carrier is moving away. The
distance from one restraining clamp to its support, while the other
clamp is resting on its support, shall be of 5 cm maximum.
The driving system shall be such that the carrier turns smoothly
and without jerks when it reverses from one direction to another.
A sample of flexible cable about 5 m long shall be stretched over
the pulleys, as shown in figure 1 , each end being loaded with a
weight. The mass of this weight and the diameter of pulleys A and B
are given in table 1 .
