Igus has introduced the Chainflex CF5 control cables and the CF6 shielded cable – now suitable for worldwide machine export – as a new standard with a 600V rating according to UL.

After a short transition period, the bundled cables will replace the Igus CF5/CF6 predecessors that are currently rated to 300V.

Justin Leonard of Igus UK said: ‘By doubling the UL rating to 600V, the new Chainflex CF5 and CF6 600V UL cables can be used all over the world for connection to motors.

‘In the US, for example, many applications with motors prescribe a voltage of 480V.

‘In addition, NFPA 70 prohibits cables of different voltages being routed in one cable channel.

‘So, for example, if 600V is required in connection with a servo frequency converter, this is the strict requirement for all the cables used, even if these are actually operated at lower voltages,’ he added.

The new control cables have an outer PVC jacket that is resistant to oil according to DIN EN and are bundled in very short pitch lengths around a highly tensile-resistant core rope.

The copper stranding has been optimised for dynamic use in energy chains.

The gusset-filled extruded inner jacket of the shielded CF6 600V UL range and the gusset-filled extruded outer jacket of the non-shielded CF5 600V UL range route the wires within the cable in the longitudinal direction, increasing the durability of the cable.

Thanks to the specially designed braided shield with the high optical coverage of 90 per cent, high EMC protection is said to be ensured even after millions of double strokes.

Alongside the logo marking the appliance wiring material (AWM) cables, the UL temperatures, UL voltage ratings and continuous production length (metres) markings are all printed on the new cables.

The UL approval for the CF5/CF6 600V UL has been granted on account of its special material combination and not only stands for flame resistance but also for tested quality.

Igus

Igus is the largest producer of reinforced plastic energy chains and injection-moulded polymer bearings. The range of polymer bearings includes Iglidur plain, Igubal spherical and Drylin linear bearings. They offer an excellent price-to-life relationship and are developed under the toughest conditions. They are oil, maintenance and lubrication free, low wear, resistant to dirt and dust, corrosion free and simple to fit. Igus also has the data to precisely predict the lifetime of these bearings within a specific application.

Energy chains are the umbilical cord of modern machines. They minimise downtime and protect, support and extend the service life of cables and hoses. The broad range incorporates more than 30,000 innovative, low-cost products. From the smallest ‘micro’ chain to the largest chain in the world, the E4.350, Igus energy chains are capable of long and short travel distances at high speeds in all axes.

Igus also has its own cable series, Chainflex, specially designed with energy chains in mind. They are highly flexible cables, offering a long service life and very small bending radii. A wide range is available, from small signal cables to large power cables, high-speed data cables and glass fibre-optic cables.

The company’s energy chains and Chainlflex cables can be delivered as a fully harnessed and pre-assembled Readychain system, cutting purchasing, warehousing and installation costs.
