product report

BizLink develops and manufactures cables specifically  for tunnel applications, that meet the unique challenges. The requirements for this application are aimed to ensure that equipment within the tunnels continues to function  as long as possible in the event of a fire.

In the event of a fire, critical power and data connections must be maintained in order to guarantee the functionality of the tunnel systems.

Key features for cables in tunnels include:

  1. Fire Resistance: Tunnel cables must be fire-resistant to ensure safety in the event of a fire and prevent the spread of fire.

  2. Durability: Cables must be resistant to external influences such as moisture, vibrations, pressure, and mechanical damage.

  3. Easy Installation: Due to the difficulty of installation, tunnel cables should be designed for easy installation, maintenance, and repair.

  4. Corrosion Resistance: Tunnel cables should also be resistant to corrosion caused by environmental factors such as moisture and chemical substances.

  5. EMC Compatibility: Electromagnetic compatibility (EMC) is crucial, as tunnels often house numerous electrical systems. Therefore, tunnel cables should be designed in such a way that they do not cause or are sensitive to electromagnetic interference.

BizLink offers two cable types within this product group that meet these high demands:

• Fire-resistant Cat Cables PH 180 (Cat 5, 6, 6A, and 7)

• Sprinkler Cables
