NSSHCGEOEU TENAX®–STREB
Cable for coalface lighting according to DIN VDE 0250, Part 812
Technical data: 
NSSHCGEOEU TENAX®–STREB
CONSTRUCTION
1. Flexible tinned copper conductor, class 5
2. Coloured core insulation of rubber compound of type 3GI3, cores wrapped with rubberized textile tape
3. Layer of semi-conducting rubber compound
4. Inner sheath of rubber compound of type GM1 b
5. Foil wrapping
6. Concentric earth conductor – helix of copper-steel strands
7. Outer sheath of chlorinated rubber compound of type 5GM5, abrasion, tear and oil resistant, selfextinguishing
A. Working core
B. Monitoring core – as a flexible copper-steel conductor covered with semi-conducting rubber compound. Three monitoring cores are twisted with working cores together (location in outer interstices).
Application
For connection of lighting installation and stationary drives with high mechanical load, especially in mines. Concentric phase monitoring core and overall concentric earth conductor facilitate monitoring of the cable from standpoint of insulation faults and damages that are produced by external effects. For this reason can the cable be used without additional mechanical protection.
