TUNNELFLEX-PUR HF cable is designed to supply power to mobile equipment operating in mining and tunneling environments with high risk of mechanical damage. This flexible cable, featuring a halogen-free polyurethane sheath, is optimized for applications where the cable is deflected in one plane only, lacking anti-twisting protection. It supports a maximum travel speed of 60 m/min, making it ideal for dynamic but linear cable movement scenarios
Product Features
Halogen-Free Polyurethane Outer Sheath: Flame retardant, flame resistant, and highly resistant to abrasion, tears, oils, and chemicals for harsh mining and tunneling environments.
Flexible Copper Conductors: Class 5 finely stranded copper ensures excellent flexibility and electrical conductivity.
Optimized for Single-Plane Deflection: Suitable for applications where cable twisting does not occur, enhancing cable life and performance.
High Mechanical and Thermal Resistance: Supports high mechanical stresses, wide temperature ranges, and high short-circuit withstand capability.
Certified Safety and Performance: Complies with multiple international standards ensuring reliable and safe operation.
Application Areas
Ideal for power supply to mobile mining and tunneling equipment subjected to frequent dynamic loads, especially where cable deflection is primarily in one plane without twisting.
Installation and Maintenance
Can be installed in fixed or flexible configurations considering bending radius recommendations. Suitable for operation on drums and fixed installations. Regular inspection recommended to ensure cable integrity and performance.
Customization Services
Available in different core numbers (2 or 3 phase) and customized lengths to meet specific site requirements.
After-sales Support
Full technical support, warranty assurance, and field service available to optimize cable functionality and service life.
