NSSHCGEOEU Low-Tensile Coal Cutter Cable 0.6/1kV

NSSHCGEOEU Low-Tensile Coal Cutter Cable

This page covers the low-tensile NSSHCGEOEU build: a 0.6/1 kV screened and monitored coal cutter cable to DIN VDE 0250 Part 812, designed for machine routes that impose extreme bending on the cable but only low tensile stress. Its defining feature is the bending radius, 1.5 × D static and 2.5 × D flexing, which is markedly tighter than the high-tensile version of the same designation.

The difference is in the earth path. This build uses a reinforced concentric earth conductor formed as a spiral of copper and steel wires, which tolerates very tight repeated bending. The high-tensile build instead uses a copper-steel tensile braid, which carries pull but will not follow the same radius. Choosing between them by designation alone is the most common specification error on coal cutter routes.

• Rated voltage: 0.6/1 kV.
• Bending radius: 1.5 × D static, 2.5 × D flexing.
• Duty: extreme bending under low tensile stress.
• Monitoring: phase-concentric monitoring screen plus common concentric earth conductor.

The phase-concentric monitoring shield and the common concentric earth conductor, used with suitable monitoring equipment, allow the cable to be watched for insulation faults and for damage caused by external influences. For routes that pull the cable, use the high-tensile NSSHCGEOEU coal cutter cable instead; for saddle-earth constructions see NSSHKCGEOEU.

NSSHCGEOEU Low-Tensile Cable Construction

The layer sequence below is the low-tensile build. The spiral copper-steel concentric earth conductor in position 6 is what permits the 1.5 × D static radius; it is not the tensile braid used in the high-tensile construction.

Designation elements

KON is the concentric earth conductor, ST a signalling or control core, and ÜL the monitoring conductor. A build written 3 × 25/16 KON + 2 ST + ÜL therefore has three 25 mm² working cores, a 16 mm² concentric earth, two signalling cores and one monitoring conductor.

Alternative construction

The cable can also be supplied with three control cores. In that case the monitoring conductor is inductively balanced and executed as a wrapping of tinned copper wires over the insulation of the control cores.

NSSHCGEOEU Low-Tensile Applications

The low-tensile build connects mobile machines under very high mechanical load, predominantly in mining, and is particularly suited to extreme bending stress at low tensile stress. Coal-cutting machines are the primary application.

• Coal-cutting machines on routes with repeated tight deflection.
• Machine loops and festoon-like paths where the cable bends hard but is not pulled.
• Installations requiring insulation-fault and external-damage monitoring through the concentric monitoring screen.
• Routes where a tensile-braided cable would not achieve the required radius.

Application boundaries

This construction is not a substitute for a tensile-braided cable. Where the route pulls the cable, over guide pulleys, on a reel or behind an LHD, select the high-tensile build or an armoured construction instead.

Reference designation cross-reference

This coal cutter cable is catalogued under two reference names that mark the same low-tensile build.

For the full list of reference designations and the TEBAOFLEX build each one maps to, see the mining cable designation cross-reference.

Trademark note: TENAX®, TROMMELFLEX®, FELTOFLEX® and SCHRÄM® are trademarks of their respective owners, and TEBAOFLEX is neither affiliated with those companies nor reselling their cable. What we supply is the equivalent construction: we manufacture to the same VDE type designation and published construction, and every designation listed here can be quoted and supplied as a TEBAOFLEX build. The names appear so that an enquiry written in those terms reaches the matching construction, which is made to the standards and construction confirmed for the order.
