Application Cases of RIT-(N)TMCGETMPU

Case 1: Underground Metal Mine – Continuous Miner

The application site is a deep underground copper mine in Chile, and the core equipment is a 6/10 kV continuous miner. The tunnel space is narrow, the cable is in a wet environment all year round, and it will generate continuous torsion of about ±20° per meter during the operation of the miner. Sharp ore particles also cause serious abrasion to the cable sheath.

The project selected RIT-(N)TMCGETMPU 6/10 kV 3×70 mm² cable. The cable runs 24 hours a day in the ambient temperature of -20°C to +40°C. Within two years of operation, there is no fault caused by torsion and abrasion. It completely eliminates unplanned shutdowns due to cable damage and improves the overall operation efficiency of the mining equipment by 15%.

Case 2: Urban Tunnel Project – TBM Power Supply

This case is an urban metro tunnel construction project in Europe, using large Tunnel Boring Machine with a rated voltage of 12/20 kV. The cable laying length reaches 300 to 500 meters. During the tunneling process, the cable is continuously reeled and bears long-distance tensile load, and is often soaked by muddy water.

The construction team adopted RIT-(N)TMCGETMPU 12/20 kV 3×120 mm² cable. Its excellent tensile resistance and waterproof structure keep the insulation performance stable for a long time. The cable can withstand the maximum tensile force of 45 kN during reeling. After putting into use, the cable replacement frequency is reduced by 70%, providing a solid guarantee for the smooth progress of the tunnel project.
