Bus cables, designed specifically for constantly moving energy chain systems in industrial applications, have highly abrasion-resistant TPE outer jackets.
Igus has now developed a completely new series of bus cables, designed specifically for constantly moving energy chain systems in industrial applications. The special cables, 'Chainflex CFBUS', have highly abrasion-resistant TPE outer jackets and are now available for standard field bus systems. The cables also conform to DESINA, UL and CSA standards.

(Abbreviations: DESINA is Distributed and Standardised Installation technology for machine tools and manufacturing systems.

UL is Underwriters Laboratory.

CSA is Canadian Standards Authority.) Experiments performed in the igus laboratory proved CFBUS.001 Profibus cables could achieve more than 14 million double strokes (DH) at a bending radius of just 6.5 x d (S = 5m, V = 3.5m/s; a = 7.5m/s2).

No damage to the cable or impairment of its transmission properties was detected.

Machinery manufacturers now have the option to use a mechanically sophisticated cable for applications with longer traversing distances and transmission paths.

* Protection against mechanical forces - the design and materials used for Chainflex CFBUS cables ensure the sensitive core insulation is always well protected.

The TPE outer jacket is highly abrasion-proof, oil-resistant and flame-retardant and is extruded at high pressure to stabilise the cable against any arising tensile and compressive forces.

The bus elements, which are stranded with an especially short pitch length, are channelled through a gusset-filled extruded TPE inner jacket and protected against excessively high mechanical stress during the bending process.

* Suitable for clean-room use - the TPE jacket material used is also suitable for clean-room applications: a fact now established by the Fraunhofer Institute for Production Technology and Automation (Stuttgart, Germany).

According to the Institute, this material can be used in sensitive environments at traversing speeds up to V = 1m/s in clean-rooms of ISO class 3 Note: ISO Class 3 pursuant to the very strict DIN EN 14644-1 standard complies with Classes 1 of the two standards, VDI 2083 and US Fed.
