Enter the TENAX M Medium Voltage Reeling Cable, a specialized engineering marvel designed to deliver electricity to large mobile equipment like excavators, spreaders, and construction machinery. This cable isn't just a wire—it's a lifeline engineered for the harshest environments, ensuring uninterrupted operation in reeling systems that wind and unwind as machines move. Based on rigorous standards like DIN VDE 0250-813, the TENAX M stands out for its durability, flexibility, and resistance to extreme conditions.
Advantages of the TENAX M Medium Voltage Reeling Cable
The TENAX M's advantages stem from its blend of robustness and adaptability, setting it apart in cable technology. First, its mechanical resilience shines in high-stress applications. With a max tensile load on the conductor of 20 N/mm² (25 N/mm² under acceleration), it withstands the pulls and jerks of heavy machinery. Torsional stress tolerance up to 100°/m prevents twisting failures, common in lesser cables during reeling.
Durability is another key edge. The outer sheath's superior abrasion and tear resistance, coupled with oil, ozone, and UV protection, extends service life in harsh settings like dusty mines or oily construction sites. This reduces replacement frequency, cutting costs and environmental impact—aligning with sustainability trends.
Electrically, the semiconductive layers ensure even field distribution, minimizing partial discharges that degrade insulation over time. High voltage ratings (up to 50 kV options) support powerful equipment without upsizing cables, optimizing space on reels.
Flexibility in temperature extremes—from Arctic-like -40°C to sweltering 80°C—makes it versatile globally, including South Africa's varied climates. Fire resistance per international standards adds safety, crucial in confined spaces like underground mines.
Economically, faster travel speeds (up to 100 m/min rewinding) boost productivity. Without integrated fiber-optics (as in PROTOLON(M)-R variants), it focuses purely on power, simplifying installations and lowering costs for non-data needs.
In essence, the TENAX M offers reliability that translates to operational efficiency, safety, and cost savings—advantages that resonate in industries facing rising energy demands and regulatory pressures.
Usage Scenarios for TENAX M in Real-World Applications
The TENAX M excels in scenarios involving large mobile equipment requiring medium voltage power via reeling systems. Primary uses include mining excavators and spreaders, where cables feed power as machines traverse vast pits. In construction, it powers cranes and drilling rigs on sites with constant repositioning.
Ports and material handling benefit too; stacker-reclaimers in bulk terminals use it for seamless power during stacking and reclaiming. In renewable energy, it's suited for mobile wind turbine maintenance equipment or solar farm trackers needing flexible power.
South Africa's industrial landscape amplifies these scenarios. With its mining sector contributing over 7% to GDP, TENAX M-like cables are vital for open-pit operations in the Witwatersrand Basin or platinum mines in Rustenburg. Here, reeling cables endure dust, vibrations, and high loads from bucket-wheel excavators.
Emerging trends include electrification of mining fleets to reduce diesel emissions, aligning with South Africa's Just Energy Transition. TENAX M supports hybrid or electric excavators, providing medium voltage for high-power needs without fixed infrastructure.
In manufacturing, it's used in automotive plants for robotic arms on rails, ensuring power during assembly line movements. Overall, any setup with mono-spiral or cylindrical reels benefits from its design, preventing kinks and failures.
