chainflex® motor cables now with higher temperature approval for 90°C and 1000V

TPE motor cable with new insulation material for improved temperature stability with higher UL temperature of 90°C

The new high-end motor cables from chainflex are designed with improved core insulation for optimum temperature resistance up to 90° Celsius according to UL. In combination with a voltage class of 1000V, this allows decisive savings in installation space and construction costs.

Order directly now!

This latest generation of chainflex® motor cables for moving applications supplies electric drives and motors with power; as always, the cables have appropriate UL certification for up to 1000V and (new) 90°C. This is currently needed more and more often, since many new plastic plug-in connectors cannot as effectively dissipate the heat that arises. That means that the cable will have to stand up to higher temperatures, which this innovation now allows. With these abilities, the CF34.UL.D and CF35.UL series are particularly suitable for highly demanding applications such as storage and retrieval units, processing machines; machine tools or also outdoor cranes.

... reduce costs & increase service life

In the crane and material handling sector, installations are increasingly getting bigger and working at an ever-higher dynamics around the clock. This means, in addition to the ever-higher demand for energy, there are rising requirements on the components used, which have to withstand ever-increasing loads all 365 days of the year.  The new chainflex motor cables can be used in indoor and outdoor applications due to the special conductor structure as well as the combination of the materials used.
There they are already in use in more than 10,000 port facilities worldwide and have therefore proven themselves in practice and under harsh application conditions. The fields of application include ship-to-shore cranes, bulk cargo handling cranes, RTGs, RMGs, Goliath cranes, spreaders, reach stackers, etc.

Motorised drums vs. Energy chains

White paper ECS vs. cable drums  

For long travels, the so-called motorised cable drums can be used as energy supply systems. As an alternative, igus offers complete energy chain systems, which show their advantages especially on long travels, as is clearly shown in the following white paper.
