EVAVB / EVAVB-F2 Construction
| Conductor | Cu stranded compacted circular and sector, according to NBN C 33-121 (IEC60228 class 2) |
| Insulation | PVC compound |
| Cable assembly | three insulated phases are twisted with fillings and tape support |
| Inner sheath | polymer material |
| Armour-screen | of the two steel tapes underneath the tapes for improving the permeability are laid Cu wires |
| Outer sheath | for EVAVB -PVC compound for EVAVB - F2 - PVC compound flame retardant |
EVAVB / EVAVB-F2 Application
- Direct Burial: The double-steel-band armor provides exceptional mechanical protection against soil pressure, stone impact, and damage from accidental excavation tools, allowing for direct burial without the need for additional conduit protection. When burying the cable directly, it is generally recommended to install warning tape to mark the cable’s location.
- Industrial and Power Networks: Widely used in industrial facilities and power distribution networks as fixed-installation power transmission cables. Their structural design is robust enough to withstand mechanical stresses that may occur in factory environments.
- Installation in Dedicated Channels: Suitable for use in cable trenches, conduits, tunnels, and cable trays. In these applications, the armor layer also provides the necessary protection.
EVAVB / EVAVB-F2 Standard
- NBN C 33-121

EVAVB / EVAVB-F2 Feature
- Double-layer steel tape armor: The cable features two layers of steel tape as armor, providing exceptional mechanical protection against compression and impact.
- Suitable for direct burial: Thanks to its robust armor, this cable can be buried directly underground without the need for additional mechanical protection, and can withstand soil pressure and damage from external forces such as excavation tools.
- Built-in Copper Wire Reinforcement: Copper wires are laid beneath the steel tape to improve electrical conductivity and may serve as an effective grounding conductor.
