Type 611 Cable 6.35/11kV Flexible Copper Screened Mining Cable
Medium-voltage mining cables work under constant mechanical and electrical stress. This Type 611 Cable is designed for 6.35/11kV mining power systems where equipment uptime, safe operation, bending performance and sheath durability are critical to daily site reliability.
Type 611 Cable for Medium-Voltage Mining Equipment
This flexible copper screened mining cable is suitable for mining machinery and portable apparatus, including equipment used in hazardous areas. It is commonly used for section feeders, open cast mining, medium-sized draglines, shovels and drills where a robust 6.35/11kV cable is required.
Key Benefits
Reliable 6.35/11kV Power Transmission

Why EPC Buyers Choose This Type 611 Cable
For mining EPC projects, the cable must do more than match the voltage rating. Buyers need to check conductor class, screening, pilot core arrangement, ECC requirements, bending radius, pulling tension and jacket resistance before approval. This Type 611 Cable gives engineers a clear specification for medium-voltage mining systems where durability and safety documentation matter.
The Type 611 ECC Cable option is especially useful when earth continuity is part of the project requirement. The TPU jacket with reflective tape also supports better visibility around moving machinery, helping maintenance teams identify cable routes more easily during daily operation.
