Repeated bending tests on cables

The test consists in simulating the possible application of the cable under extreme working conditions, in order to verify whether or not it possesses the quality characteristics required by the reference standards.

The cable sample must be bent forwards and backwards with angles of up to 270° with the two extreme positions forming a 135° angle on both sides of the vertical section while the sample is subjected to traction.

The equipment can be used for tests only on cables and on cables with connectors.
It is capable of performing two types of cycles:

• Moving the sample from the vertical position to the extreme right position and then bending it to the extreme left position before returning to the original vertical position.
• Moving the sample from the vertical position to the extreme right position before returning it to the original vertical position.

The parameters that characterise the test include: bending speed and angle, radius of the bend, number of cycles and traction load.
The cable must resist for a defined number of bending cycles without damage (interruption) under the stated conditions.

SIF, through its collaboration with the most important testing and research institutes, comparing notes with customers and scrupulous analysis of normative requirements, has been able to develop a product that focuses primarily on:

• SAFETY STANDARDS
• PREVENTING WEAR AND TEAR OF MECHANICAL PARTS
• CONFORMITY WITH STANDARDS CEI EN 50289-3-9, GOST 12182.1, CEI EN IEC 61010-1

The true value added of the equipment consists of the innovative solutions created through the inventiveness of our Research & Development Team, which has succeeded in uniting creativity and engineering to: 

• TEST DIFFERENT TYPES OF CABLES
• FACILITATE THE TEST SET UP
• DETECT AND REPORT DAMAGED CABLES

Elements that make up the testing system:

1. Cable movement system - Design that eliminates shock due to sudden inversion of direction
2. Cable attachment system - Bending arm with adjustable clamps
3. Pulley position adjustment system - To maintain the axis of oscillation
4. Interchangeable pulley and weight kit - According to the type of cable to be tested
5. Operator control panel to set and visualise testing parameters - Bending angle and speed, cycles set/performed, type of cable, alarms and signals
6. Bearing mechanical structure - with protective glass door and testing control
7. Safety Modules - Emergency and interlock button with opening of protective door
