| Oversheath | PE-plastic PELLD |
12/20 (24) kV AXALJ-F TT 3-core Cable Application
- Direct Burial: The cable can be buried directly in the ground and can even withstand the mechanical stress caused by plow-style installation.
- Outdoor overhead installation: Due to the lightweight aluminum conductor and the UV-resistant outer sheath, it can also be suspended between utility poles or towers.
- Duct installation: It is also suitable for installation in cable ducts or cable trays.
- Commonly used for power supply in the following infrastructure:
- Feeder lines for transformer stations and substations.
- Wind farms and solar power plants.
- Power distribution for large industrial and commercial facilities such as factories and data centers.

12/20 (24) kV AXALJ-F TT 3-core Cable Feature
- Longitudinal Water Protection: Water-blocking material is used inside the conductor, and a water-swelling semiconductive water-blocking tape is wrapped around the insulation. If the outer sheath is damaged, these materials will rapidly expand, effectively preventing moisture from spreading along the length of the cable.
- Radial Water Protection: A layer of dense aluminum/polyethylene (Al/PET) laminate tape is bonded beneath the outer sheath to prevent moisture from penetrating vertically into the cable from the outside.
- Operating and Temperature Limits: The minimum installation bending radius of the cable is typically about 15 times its outer diameter. Additionally, the minimum installation temperature is -20°C; caution is required during installation in cold weather.
