(N)TSCGEWOEU-TR 3.6/6kV – 18/30kV MV Trailing Cable | Heavy-Duty Open-Pit Mining

(N)TSCGEWOEU-TR is a heavy-duty medium voltage trailing cable specifically designed for open-pit mining equipment operating under extreme mechanical stress, abrasion, and tear during continuous trailing over rough terrain. Manufactured by TEBAOFLEX to VDE 0250-813, the TR variant features enhanced 5GM5 inner and outer sheath system with improved tear and abrasion resistance, bonded sheath construction, and a black outer sheath optimized for UV and wear resistance. Rated from 3.6/6kV to 18/30kV with a 3+3 core configuration, it is the preferred cable for draglines, excavators, mobile crushers, and dumpers where the cable is dragged across rock, gravel, and soil surfaces.

(N)TSCGEWOEU-TR — TEBAOFLEX MV Trailing Cable for Open-Pit Mining

What TR Means

TR designates the Trailing variant, specifically engineered for cables that are dragged behind mobile equipment across open-pit mine floors. Unlike reeling cables that wind onto drums in controlled layers, trailing cables are subjected to continuous abrasion against rock, gravel, and soil, impact from falling debris, and potential crushing by heavy vehicle tracks. The TR variant addresses these conditions through reinforced sheath design and optimized compound selection.

Why TR is Essential for Open-Pit Trailing

Hazard Standard Cable Risk TR Solution
Dragging over sharp rock Outer sheath cuts through, moisture ingress Enhanced 5GM5 tear resistance + bonded sheath prevents delamination
Repeated impact from falling debris Core deformation, conductor breakage Double 5GM5 sheath system absorbs impact energy
UV exposure in continuous sunlight Sheath cracking, reduced service life Black 5GM5 with superior UV stabilisation
Oil and fuel spills from mining equipment Sheath swelling, loss of mechanical properties Oil-resistant 5GM5 compound per EN 60811-404
Extreme temperature variation Sheath embrittlement in cold, softening in heat -50°C to +80°C fixed rating
Vehicle track crushing Permanent core damage Reinforced anti-torsion braid distributes crush load

Why Choose TEBAOFLEX (N)TSCGEWOEU-TR

TEBAOFLEX manufactures the TR variant with bonded 5GM5 sheath technology in our ISO 9001 certified facility. Each cable is tested for conductor resistance, high voltage withstand, and sheath integrity before dispatch. For open-pit mining operations where trailing cables are replaced every 6-18 months due to wear, the TR variant’s enhanced abrasion resistance provides measurably longer service life, reducing both cable replacement cost and operational downtime.
