NTS...WOEU TENAX®-TT LWL
Trailing cable with integrated optical fibres according to DIN VDE 0250, Part 813
Technical data: 
NTS...WOEU TENAX®-TT LWL
CONSTRUCTION
1. Flexible tinned copper conductor, class 5
2. Core insulation of rubber compound of type 3GI3 based on EPR
3. Inner semi-conducting layer – up to 6 kV. It is completed with outer semi-conducting layer above 6 kV (these two semi-conducting layers form together with insulation a void free (homogeneous) radial field).
4. Inner sheath of special synthetic rubber of type GM1 b
5. Outer sheath of chlorinated rubber compound of type 5GM3, oil resistant and self-extinguishing, reinforced by inserted braid of glass fibres, which serves as torsion protection
A. Working core
B. Earth conductor – 2 earth conductors are located in outer interstices of twisted cores
C. Optical core – properly protected 1 optical element is located in the third interstice of twisted cores. The optical element usually contains 2 to 12 multimode fibres 50/125 μm. Other type and number of fibres on request.
Application
For connection of large mobile equipment e.g. excavators, stowing machines, full-portal gantry cranes etc. The cable is suitable for motorized winding at singlespindle or level winches.

Integrated optics provides numerous advantages for effective communication among mobile equipment and their control:
– Large bandwidth and high transmission rate, immunity to electromagnetic disturbances, no crosstalk
– Absence of metallic lines between transmitter and receiver
– Data transmission is integrated in the trailing cable that is designed in order to withstand a rough mechanical stress
