Following a series of inhouse
tests over a period of
two years, energy chain and
cable specialist, igus UK, now
certifies that its Chainflex
CF11 and CF211 series can
operate reliably and safely in
smaller bending radii.
The permissible bending radius for the CF11 TPE measuring system cable has been reduced by 32% from 10x diameter to 6.8xd, and that of the CF211PVC variant by 25% from 10xd to 7.5xd. The tests, which paid special attention to the cable shield, core pitch lengths and the individual strand size of the core wires, confirmed that cables survived more than 30 million double strokes, or 36,691km travel, in the energy chain with a test radius of 5xd.
The Chainflex CF11 data cable has an abrasion-proof and bend-resistant, halogenfree, oil and bio-oil-resistant TPE outer jacket and an inner jacket also made of a TPE compound. It is said to have extremely stable braiding.
