The Problem MT PLUS Solves
Standard medium voltage reeling cables are built with generous wall thicknesses and wide manufacturing tolerances to ensure compliance under all conditions. This results in a cable that is heavier and thicker than the application technically requires — consuming drum capacity that could otherwise hold more cable length, and adding dead weight that reduces the payload of the host machine.
The MT PLUS variant addresses this directly. By applying tighter manufacturing tolerances, optimized lay-up geometry, and precision-controlled sheath extrusion, TEBAOFLEX reduces both the overall diameter and the weight per meter by approximately 10-15% compared to the standard (N)TSCGEWOEU — without reducing conductor cross-section, voltage rating, or mechanical ratings.
What MT PLUS Means
MT stands for Medium Tension (MV range), and PLUS designates the optimized compact construction. It is not a downgraded economy version — the core electrical and mechanical specifications remain identical to the standard design. The weight and diameter reduction comes from engineering precision, not material compromise.
Where Weight and Diameter Reduction Matters Most
| Application | Benefit of MT PLUS |
|---|---|
| High-rise crane and boom reeling | Lighter cable reduces sag and required tension at maximum working height |
| Container crane gantry (E-RTG) | Longer cable per drum = fewer changeovers per shift |
| Mobile excavator and shovel payload | Every kg of cable weight saved is available for material payload |
| Deep shaft vertical reeling | Reduced self-weight lowers the tensile load on the cable termination |
| Festoon systems with tight bend radii | Smaller OD enables tighter bend radius within same guide clearance |

Key Advantages of MT PLUS
Longer Cable per Drum — With the reduced diameter, a standard 2.2m drum can hold up to 15% more cable length, reducing drum change frequency and splice joints in long reeling runs.
Higher Machine Payload — On draglines, excavators, and cranes where the cable mass is carried by the machine, every kilogram saved through the MT PLUS design translates directly to increased material handling capacity.
Same Full Certification — The MT PLUS carries the same VDE 0250-813 certification, same 5GM5 outer sheath, same anti-torsion braid, and same electrical ratings as the standard cable. The weight reduction does not compromise compliance.
Lower Shipping Cost — For project-based supply, the reduced cable mass lowers freight cost per meter, particularly for air-freighted urgent spares or long export shipping routes.
