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 . Cable Testing Equipment
