Alloy improves cable life
Chainflex CF98 cable from Igus incorporates an alloy that lets it withstand more than 30 million energy chain cycles, at a bending radius of less than four times the cable diameter.

Copper was found to reach its physical limit at bending radii of under five times the diameter.
Due to its molecular structure, copper becomes brittle and breaks very easily when subjected to a high degree of mechanical stress.
Therefore a material with a softer structure was needed.
In tests, a cable with the new alloy (test specimen A), the same cable with copper (test specimen B), a braided cable (C) and a cable with a rope construction (D) were compared.
The first test analysed a number of conductors and cross sections, but the second test specifically compared test specimens A and B.
The cable material was the only distinguishing characteristic.
The test results showed specimen A had no single-wire rupture, even after more than 28 million cycles.
Test specimen B on the other hand only reached around 1.4 million cycles before the cable was completely destroyed.
This meant that the alloyed cable had a service life 19 times longer than the copper cable.
Chainflex CF98 was successfully tested at a bending radius of 3.2 times the diameter with the new alloy.
The control cables are made of an abrasion-resistant, extruded outer jacket, are resistant to oil and UV rays and free of PVC and halogen.
The control cable is available ex-stock without any cutting costs or extra charges for small quantities.
Applications include automatic tram doors, cash dispensers and semiconductor pick-and-place robots. Request a free brochure from Igus UK ...
