3.6/6kV to 18/30kV R-(N)TSCGEWÖU Medium Voltage Reeling Cable – VDE 0250 Part 813 – Open-Cast Mining Excavator Cable

Machinery & Equipment Mining Cables
Description

Product Overview

The R-(N)TSCGEWÖU Medium Voltage Reeling Cable is a heavy-duty power cable engineered for the most demanding material handling applications in open-cast mining and heavy industrial environments. Designed for use with mono-spiral and cylindrical reeling systems, this cable provides reliable power transmission to large mobile machinery such as excavators, dumpers, and crushers. Its sophisticated construction, featuring semi-conductive screens, an anti-torsion braid, and robust synthetic sheathing, ensures exceptional performance under continuous flexing, high mechanical stress, and harsh environmental conditions.

Key Features & Benefits

  • Engineered for Extreme Reeling Applications: Specifically designed for high mechanical stresses associated with continuous spooling and unspooling on mono-spiral and cylindrical reels.

  • Superior Mechanical Durability: Excellent resistance to tearing, impact, and abrasion ensures long service life in rugged mining environments.

  • Advanced Anti-Torsion Design: Integrated polyamide braid between sheath layers provides protection against torsional forces during reeling operations.

  • Comprehensive Environmental Resistance: Formulated to withstand UV radiation, sunlight, ozone, and oil exposure. Flame retardant for enhanced operational safety.

  • Wide Temperature Range: Suitable for continuous operation from -25°C to +90°C, with fixed installation capability down to -40°C.

  • Clear Identification: Features embossed marking for easy cable identification and traceability throughout its service life.

  • Full Screening for MV Applications: Conductor and insulation screens with controlled resistivity ensure safe and reliable medium voltage performance.
