Mechanical Test for Flexible Handling Cables
In Nexans factories, strict quality control is one of the
most important tasks to ensure a long-life term of our
products.
Due to the high mechanical, torsion and tensile
stresses appeared in handling applications, Nexans
carry out extreme mechanical type tests before a new
product range is introduced into the market. The test
conditions are much more harder then the reality in
the application.
Climate-tests, continous-tests for artificial ageing,
mechanical and chemical compound properties (e.g.
tensile strength, elongation, density, tear resistance
and abrasion, oil, ozone, UV resistance) serve to
increase the operating period of our products. All
these tests are the basis for Nexans to improve the
high quality level and cable performance.
 Torsional Resistance Test / Anti twisting test
The torsional resistance test is carried out to evaluate
the mechanical behaviour of cable with respect to,
it’s twisting properties at simultaneus tensile load,
different torsional angle and twisting speed.
Operating conditions:
• tensile force: up to 4,000 N
(depending on cross-section)
• torsional force: 200 Nm
(depending on cable length and cross-section)
• torsional angle: ± 100°
(depending on clambing length)
The anti twisting test is carried out to evaluate the
resistance of the cable regarding of twisting force.
 Alternating/Reversed Bending Test
In line with the VDE 0472 standard part 603. To
show the operating conditions under enhanced
bending stress. This test permits us to develop better
conductor design.
Operating conditions:
• cycle movement: max 180°
• tensile load: max 3,000 N
(depending on cross-section)
Roller Bending Test
The bending test is used for operating time-lapse
evaluation of flexible cables for middle and heavy
duty service with regard to:
• travelling behaviour over pulleys under
simultaneous pulling force
• determination of broken wires under
service
• quality of repairing points
 Drag Chain Test
This test facility permits the combination of small
bending radius, with high acceleration and high
speed movement. |
