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

• Designed for 6.35/11kV medium-voltage mining power applications.
• Flexible class 5 tinned annealed copper conductors support practical handling and reliable current flow.
• Semi-conducting rubber screen helps support stable electrical performance in screened power cores.

Screened Power Cores with Pilot Core Design

• Three individually screened power cores are laid up with three insulated pilot cores.
• Pilot cores support monitoring, control and safety-related functions in mining equipment connections.
• Type 611 ECC version is available when one pilot core needs to be replaced by a tinned earth continuity conductor.

Heavy-Duty Jacket for Harsh Mine Conditions

• Extra-heavy-duty TPU jacket according to ICEA S-75-381 Tab. 3-3.
• Designed for abrasion resistance, tear resistance and flame retardant performance.
• Suitable for environments requiring UV, ozone and oil resistance.

Built for Safer Installation and Handling

• Minimum bending radius data helps EPC teams design safer cable routes.
• Maximum recommended tension supports controlled installation planning.
• Transparent sheath with orange and silver reflective tape improves cable visibility around mobile equipment.

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.
