NSSHKCGERLOEU SCHRÄM TENAX®-ZE
Armoured cable for cutting machine Schräm-TENAX®-ZE, DIN VDE 0250, Part 812
Technical data: 
NSSHKCGERLOEU SCHRÄM TENAX®-ZE
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 particularly high mechanical strength. Cores are wrapped with rubberized textile tape. Cores are twisted around a centre saddled separator.
3. Inner sheath of semi-conducting rubber compound
4. Taping
5. Armour (braiding of steel wires)
6. Outer sheath of chlorinated rubber compound of type 5GM5, abrasion, tear and oil resistant, selfextinguishing
A. Working core
B. Signalling cores – 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. Earth conductor – distributed as strands of very thin copper wire around insulation of signalling core and as a flexible conductor of tinned copper located in saddled separator
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 stress. 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).
The cable meets requirements given in test standards DIN VDE 0472, Part 818 “Behaviour under clamping stress”. It secures that a damage produced by clamping is detected as an earth fault with maximum possible probability.
