Energy chains made of conductive ESD material are used to avoid static charge in manufacturing processes for electronic components or assemblies. Measurements of the electrical surface leakage resistance for igus energy chains with the special material igumid GC, were made back in 1992 by igus GmbH together with the PTB (Physikalisch-Technische-Bundesanstalt) in Braunschweig, supplemented by additional certifications in 1998 and 1999 according to DIN 53482, and the guidelines for static electricity ZH1/200 of the Federation of Trade Associations.
1. TRC - enclosed chip-repellent design
2. High tensile strength absorption through the "ball and socket" joint
3. Multi-axis movement - twist up to ± 10° per chain link possible in longitudinal axis
4. Impact-resistant, robust, abrasion-resistant and dirt-repellent
5. Easy assembly and disassembly - single injection-moulded part
6. High stability - due to exterior stop-dogs
7. Electrically conductive: ESD versions
8. e-chains® colour: (according to RAL, approximate) black ≈ RAL9004
9. Small bend radii and short pitch
10.
Easy attachment to the machine/robot
Technical design qualities of the igus® triflex® R TRC series of e-chains®:
approx. ±10° torsion per chain link
High tensile strength due to ball-and-socket joint
Fiber rod option for partial directional control and reinforcement
No support elements such as steel cables, springs etc. are necessary
Diverse range of accessories
Optional retraction systems reliably guide the 3D e-chains® along the robot arm and dependably prevent loop formation
TRC - Safe, enclosed, chip-repellent
Smooth and robust exterior against interfering edges
High torsion stability
Can be arbitrarily shortened or extended
Typical industries and applications
3 to 6 axes at robots
Multi-axis machine tools
Wet and cold cells
Painting applications and ESD
Sand and dust exposure
Linear motors
General mechanical engineering, etc.

In contrast to temporary conductive surface coatings or volatile incorporated antistatic agents, the additives used offer long lasting and maintenance-free conductivity. If individual e-chain components offer conductivity, this is not sufficient: the whole e-chain® from one end to the other must have continuous conductivity. All products in this catalogue are optimised in this regard and the continuous conductivity is measured and documented prior to delivery with 100% testing.
Only e-chains® that have passed this test are provided with the test seal and delivered. The colour of the triflex R chains is special because they are not slate grey (≈RAL7015) but still black, similar to ≈RAL9004. Unfortunately, this makes it somewhat more difficult to distinguish from standard materials. However, this is clearly defined via the material stamp.
