Armoured cable for cutting machine Schräm-TENAX®-Z, DIN VDE 0250, Part 812
Technical data: 
NSSHCGEOEU SCHRÄM TENAX®-Z
CONSTRUCTION
1. Highly flexible tinned copper conductor, in special flexible construction
2. Coloured core insulation of heat resistant rubber compound of type 3GI3, based on EPR, with excellent mechanical properties. Cores are wrapped with rubberized textile tape.
3. Layer of semi-conducting rubber compound
4. Inner sheath of rubber compound of type GM1 b with high mechanical strength
5. Foil wrapping
6. Concentric earth conductor as braided armour (of copper and steel wires), resistant to tensile stress
7. Outer sheath of chlorinated rubber compound of type 5GM5, abrasion, tear and oil resistant, selfextinguishing
A. Working core
B. Signalling cores – 2 cores with copper-steel conductors, capable of dilating, insulation of type 3GI3 compound (based on EPR), signalling cores located in outer interstices of twisted cores
C. Monitoring core – conductor in conformity with control core, covering with semi-conducting rubber compound. The core is located in outer interstice of twisted cores.
Application
For connection of mobile machines with very high mechanical load, especially in mines, e.g. for coal cutting machines. Suited in particular for extreme bending stressing, high tensile stress and for impact and crushing load. The armour that is resistant to tensile and torsion stress makes also in connection with high flexibility of the cable possible, to operate the cable over guiding rollers (cable cart) or to use the cable as a winding cable (LHD). Concentric phase monitoring screen and overall concentric earth conductor facilitate in connection with a suitable monitoring equipment monitoring of the cable from standpoint of insulation faults and damages that are caused by external effects.
