Quality Control
Raw Material Test
Raw Material Test for A2XS(FL)2Y MDPE 76/132 (145) kV Power Cable prioritizes ultra-high-voltage quality and longitudinal water-blocking. The detailed process includes: Supplier Certification Review: Verify stranded aluminium conductors meet IEC 60228 class 2 for purity, stranding, and conductivity; XLPE insulation compound certified to IEC 62067/IEC 60840 for electrical/thermal properties; water-blocking materials (swellable tapes/powders) and aluminium laminated foil certified for longitudinal sealing; MDPE sheath compound certified for mechanical toughness and environmental resistance. XLPE Insulation Evaluation: XLPE compound tested for tensile strength (>12.5 MPa), elongation (>200%), dielectric strength (>20 kV/mm), water tree resistance, thermal aging (135°C/168h), and hot set test (≤175% elongation after 200°C/15 min).
Process inspection
Process Inspection during manufacturing of A2XS(FL)2Y MDPE 76/132 (145) kV Power Cable maintains ultra-HV integrity and water-blocking effectiveness. Steps include: Conductor Stranding: Monitor class 2 stranding for uniform lay length, compactness, and no loose strands. Triple Extrusion: Apply semi-conductive conductor screen, XLPE insulation, and semi-conductive insulation screen in continuous triple extrusion; inline diameter scanners, eccentricity monitors, and spark testers detect voids/defects. Water-Blocking Application: Insert longitudinal water-blocking tapes/powders around core assembly to prevent axial water migration. Screening Application: Apply concentric copper wire screen and aluminium laminated foil with precise overlap/coverage for effective shielding and longitudinal sealing.
Finished Product
Finished Product Test confirms the A2XS(FL)2Y MDPE 76/132 (145) kV Power Cable meets ultra-high-voltage standards before shipment. The procedure includes: Visual & Dimensional Inspection: Examine full length for defects, uniformity, markings, and measure outer diameter/weight per meter. Electrical Tests: DC resistance, insulation resistance (>1000 MΩ·km), high-voltage AC withstand (230kV/1h or per IEC 60840), lightning impulse test (e.g., 650kV peak), partial discharge (<5 pC), and screen continuity. Water-Blocking Performance: Longitudinal water penetration test (IEC 60840 or equivalent, 1 bar/14 days or higher pressure simulation) to verify no axial water migration. Mechanical Evaluation: Bending radius (15–20× OD), tensile strength, crush resistance, and impact tests.

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.
