The finished 4/5 Cores SWA Armoured Cable 0.6/1kV CU/XLPE/SWA/PVC undergoes comprehensive testing. Routine tests include conductor resistance, AC voltage withstand (3.5kV), insulation and sheath thickness verification, and armour continuity checks. Mechanical tests cover crushing resistance, impact endurance, and tensile strength. Flame retardancy per IEC 60332-1 is verified. The process steps include sample preparation, gradual voltage ramp-up and hold period, mechanical load application (crushing and impact), environmental conditioning, post-test electrical and mechanical re-measurement, and detailed visual inspection. Additional checks cover shrinkage, heat shock, and marking durability. Only cables passing all criteria are approved, confirming the 4/5 Cores SWA Armoured Cable 0.6/1kV CU/XLPE/SWA/PVC’s superior mechanical protection, electrical safety, and suitability for demanding installations.

(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.;
