The cable sample must be tested using a device made up of a handling system cart and four pulleys. Two pulleys of the same size must be mounted on the cart and the other two must be attached to the end of the device.
The four pulleys must be positioned so the cable is horizontal.
The test consists in moving the cable back and forth (cycle) 1 m at a constant speed of approximately 0.33 m/s while it is subject to traction on the two extremities.
Moreover, during the cycles, the sample must be under tension and a test current. This depends on the type of cable used.
The handling system must ensure that the cart does not undergo mechanical vibrations due to changes in direction.
The parameters that characterize the test are: pulleys, traction load, number of cycles, tension and test current.
The cable must resist a predefined number of bending cycles without becoming damaged (interruption or short circuit) under the stated conditions
SIF, through collaboration with the main testing and research institutions, discussion with clients and careful analysis of all standards, has been able to develop a product with particular focus on:
The true added value of the equipment is the innovative solutions of the Research & Development team, which has paired creativity and engineering to:
1. Supporting mechanical structure
with a protective glass door and test control
2. Pulley adjustment system
To keep the test cable horizontal
3. Pulley kit and interchangeable weights
Based on the type of cables to test
4. Clamps for conductor connections
Positioned inside the mechanical structure for the operator’s safety
5. Current source group of up to 32A
With independent adjustments using the knobs
6. Auxiliary circuits for detection:
- Test current interruption,
- Short circuits between conductors
- Short circuits between the sample and pulleys
7. Operator control panel to configure and display the test parameters
