FAQ for Type OnGcekż-G2 Mining Cables (0.6/1 kV) – Power Cables for Mobile and Portable Equipment

1. What is the primary application of the Type OnGcekż-G2 mining cable?
This cable is specifically designed for powering mobile and portable receivers used in underground mining operations, ensuring reliable performance in harsh mining environments.

2. What is the voltage rating of this cable?
The cable is rated for a nominal voltage of 0.6/1 kV, making it suitable for medium-voltage applications typically found in mining installations.

3. What types of conductors are used in the cable's construction?
The cable employs multi-stranded copper conductors for the working (main) cores and tinned multi-stranded copper conductors for the auxiliary cores. Both conductor types comply with PN-EN 60228 Class 5 standards, ensuring high flexibility and current-carrying capacity.

4. How is the cable shielded?
A braided shield made of tinned copper wires (0.30 mm in diameter) combined with synthetic fiber is used. This shield enhances electromagnetic interference (EMI) protection and provides mechanical robustness, which is critical in the mining environment.

5. What insulation materials are used in the cable?
The working conductors are insulated with heat-resistant IEP rubber (as per PN-89/E-29100), while the auxiliary conductors use similar high-performance insulation. This ensures thermal stability and resistance to the high operating temperatures often encountered in mining.

6. How does the cable’s construction contribute to safety in mining operations?
Its multi-layer construction—featuring insulated conductors, effective shielding, and a flame-retardant outer sheath made from ON-4 rubber—provides excellent protection against electrical faults, mechanical damage, and exposure to harsh chemicals and moisture.

7. What are the available conductor configurations of this cable?
The Type OnGcekż-G2 cable is offered in 10-core, 13-core, and 14-core configurations. Each variant is designed with different numbers and sizes of working, auxiliary, and protective earth conductors to suit varying power demands in mining applications.

8. What is the cable’s maximum operating temperature?
The cable is designed to operate reliably at temperatures up to +90°C, ensuring performance under the high-heat conditions common in mining environments.

9. Which standards does the Type OnGcekż-G2 cable comply with?
This cable complies with the WT-96/K-346 standard, ensuring that it meets strict performance, safety, and durability requirements necessary for mining applications.

10. How are the dielectric strength and resistance values specified for this cable?
The working conductors are designed to withstand test voltages up to 3.2 kV, while the auxiliary conductors are rated for 2 kV. Additionally, the cable’s design includes specific resistance values at 20°C to ensure efficient power transmission over long distances.

11. Can the cable be customized for specific mining conditions?
Yes, customization is available. The cable’s conductor sizes and configurations can be tailored—upon agreement with the customer—to meet the specific power requirements and environmental challenges of different mining operations.

12. How does the cable’s design enhance durability in harsh mining environments?
The integration of robust, flexible conductors, a protective braided shield, high-quality insulation, and a flame-retardant, abrasion-resistant outer sheath collectively ensure that the cable can withstand mechanical stress, moisture, chemical exposure, and high temperatures typical of mining conditions.
