EAXECVB / EXECVB Construction
| Conductors | Cu and Al stranded compacted, according to IEC 60228 cl.2 (NBN C 30-228) |
| Inner semi-conductive layer | semi-conductive XLPE compound |
| Insulation | XLPE compound |
| Outer semi-conductive layer | semi-conductive XLPE compound |
| Water resisting element | Layer of semi-conductive water absorbing tapes |
| Metal screen | Cu wires concentrically laid and one contact of Cu tape with thickness of 0.1mm. |
| Water resisting element | water absorbing insulating tape |
| Sheath | PVC compound tipe ST2 |
EAXECVB / EXECVB Application
- Public Distribution Networks: Medium-voltage power transmission in urban and industrial areas
- Industrial Facilities: Medium-voltage power supply lines within factories
- Underground Installation: Direct burial or installation in cable trenches; the longitudinal water-blocking design makes it suitable for damp environments
- Applications Requiring Mechanical Protection: The PVC sheath provides basic mechanical protection, making it suitable for locations where the cable may be subject to external damage
EAXECVB / EXECVB Standard
- NBN C 33 – 323

EAXECVB / EXECVB Feature
- Current-Carrying Capacity and Temperature Resistance: The conductor has a maximum continuous operating temperature of 90°C and can withstand temperatures up to 250°C during a short circuit (for up to 5 seconds).
- Longitudinal Water Barrier: The letter “e” in the model designation indicates that the cable features a longitudinal water barrier, typically achieved using a semiconductive water-absorbing tape or an intumescent tape to prevent moisture from penetrating along the length of the cable.
- Mechanical Properties: The minimum bending radius is 15 times the cable’s outer diameter, and the installation temperature must not be lower than -15°C.
