Quality Control
Raw Material Test
Raw Material Test for Type 209 Flexible Copper Screened Mining Cable prioritizes mining safety and durability. Steps include: Certification Verification: Tinned copper conductors and EPR/rubber sheath meet AS/NZS 2802 standards for mining use. Conductor Testing: Tensile, elongation, conductivity, tin coating analysis. Insulation Evaluation: EPR dielectric strength, thermal stability, hot set test. Shielding Check: Tinned copper braid coverage (>80%), conductivity, braid integrity. Sheath Testing: Flame retardancy, oil/abrasion resistance, and mechanical properties. Batch Rejection: Non-compliant quarantined. Approved materials ensure the Type 209 Flexible Copper Screened Mining Cable's performance and safety.
Process inspection
Process Inspection for Type 209 Flexible Copper Screened Mining Cable enforces mining-grade quality. The procedure features: Stranding Control: Uniform tinned copper stranding. Insulation Extrusion: EPR applied with defect detection. Braid Application: High-coverage tinned copper monitored. Sheath Extrusion: Flame-retardant rubber applied with adhesion checks. Ongoing Checks: Resistance, integrity, diameter monitoring. Correction: Immediate fixes. This guarantees the Type 209 Flexible Copper Screened Mining Cable excels in mining trailing applications.

FAQ From Customers
-
What are the advantages of power cables and overhead lines?(1) Reliable operation, because it is installed in a hidden place such as underground, it is less damaged by external forces, has less chance of failure, and the power supply is safe, and it will not cause harm to people; (2) The maintenance workload is small and frequent inspections are not required; (3) No need to erect towers; (4) Help improve power factor.
-
Which aspects should be considered when choosing the cross section of a power cable?(1) The long-term allowable working current of the cable; (2) Thermal stability once short circuited; (3) The voltage drop on the line cannot exceed the allowable working range.
-
What are the measures for cable fire prevention?(1) Use flame-retardant cables; (2) Use fireproof cable tray; (3) Use fireproof paint; (4) Fire partition walls and fire baffles are installed at cable tunnels, mezzanine exits, etc.; (5) Overhead cables should avoid oil pipelines and explosion-proof doors, otherwise local pipes or heat insulation and fire prevention measures should be taken.
-
What should be paid attention to during the transportation and handling of cables?(1) During transportation, loading and unloading, cables and cable reels should not be damaged. It is strictly forbidden to push the cable reels directly from the vehicle. Generally, cables should not be transported and stored flat. (2) Before transporting or rolling the cable reel, ensure that the cable reel is firm, the cable is wound tightly, the oil pipe between the oil-filled cable and the pressure oil tank should be fixed without damage, the pressure oil tank should be firm, and the pressure indication should meet the requirements.
-
What inspections should be carried out for the acceptance of cable lines?(1) The cable specifications should meet the regulations, the arrangement should be neat, no damage, and the signs should be complete, correct and clear; (2) The fixed bending radius of the cable, the related distance and the wiring of the metal sheath of the single-core power cable should meet the requirements; (3) The cable terminal and the middle head should not leak oil, and the installation should be firm. The oil pressure of the oil-filled cable and the meter setting should meet the requirements; (4) Good grounding; (5) The color of the cable terminal is correct, and the metal parts such as the bracket are completely painted; (6) There should be no debris in the cable trench, tunnel, and bridge, and the cover should be complete.
