FR-N30XA8E-AR 18/30kV Cable Gen to NF C 33-226 - AL/XLPE/MDPE

The FR-N30XA8E-AR Triplex 18/30kV Cable is a robust triplex medium-voltage cable compliant with NF C 33-226 for efficient power distribution. It comprises three stranded aluminium conductors (AL), semi-conductive screens, high-grade XLPE insulation for reliable dielectric/thermal performance (90°C continuous), copper wire screens for grounding, and a durable medium-density polyethylene (MDPE) outer sheath offering excellent mechanical protection, moisture resistance, UV stability, and chemical resistance. The triplex design (three cores twisted together) simplifies installation in overhead aerial bundled systems or underground ducts. Compliant with French NF C 33-226 and relevant IEC standards, it provides low losses, high current capacity, and long service life in demanding environments. The FR-N30XA8E-AR is perfect for MV overhead lines, underground distribution, rural electrification, and urban networks requiring weather-resistant, durable triplex cable.

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.
