Type 61A Cable 640/1100V for Mining Trailing Applications
In mining operations, cable failure can quickly become a production issue: downtime, difficult replacement work, damaged equipment connections and safety concerns all add cost. This Type 61A Cable is designed for 640/1100V mining trailing applications where flexibility, mechanical protection and dependable power transmission are required.
Type 61A Cable for Heavy-Duty Mine Equipment
This SANS Type 61A Cable is suitable for portable electrical equipment and movable machinery used in mining environments, including hazardous areas. It is built for non-reeling applications and combines screened power cores, pilot cores and a tough TPU outer sheath to support stable operation in demanding field conditions.
Key Benefits
Reliable Power Transmission for Mining Equipment
- 95mm2 flexible class 5 tinned annealed copper power conductors support heavy-duty 640/1100V power supply.
- Tinned copper conductors help improve corrosion resistance in harsh mining environments.
- Three screened power cores provide a robust structure for movable electrical apparatus.
Pilot Cores for Control and Monitoring
- Three 16mm2 unscreened pilot cores are laid in the interstices of the cable.
- Pilot cores support control, monitoring and safety-related functions in mining equipment connections.
- The integrated structure reduces the need for separate control cable routing.
Heavy-Duty TPU Sheath for Harsh 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 where UV, sunlight, ozone and oil resistance are important.
Designed for Practical Site Handling
- Minimum bending radius of 350mm supports practical installation and movement around equipment.
- Maximum recommended tension is 4.3kN for controlled handling during installation.
- Available with black sheath or transparent sheath with orange and silver reflective tape for improved visibility.

Why EPC Buyers Choose This Type 61A Cable
For EPC contractors and mining equipment buyers, the main concern is not only whether a cable matches the voltage rating. The cable must also handle movement, resist sheath damage, maintain conductor performance and fit the safety requirements of the project. This Type 61A Cable addresses those needs with a proven SANS-based construction, screened power cores, pilot cores and a durable TPU sheath.
The reflective sheath option is useful where cable visibility matters around mobile machinery, walkways and service areas. The combination of tinned copper conductors, EPR insulation and TPU sheathing makes this cable a practical choice for buyers who need a mining power cable that is easy to specify, easier to inspect and suitable for long-term field use.
