Deep diving with the best

Bekaert has recently produced and delivered its Bezinox® non-magnetic armouring solution to the largest offshore wind farm in Scotland – Seagreen.

Bekaert’s Bezinox® solution has been used as an armouring for 196 km of export cables to deliver energy to 1.6 million households in Scotland. 

Thanks to its non-magnetic features, the energy losses are reduced significantly and transmitted efficiently. 

How can you benefit as an operator of an offshore wind farm?

  1. Bezinox® will prevent failures and energy losses, resulting in lower cost
  2. Your export cables will have a longer lifetime and high-reliability thanks to outstanding corrosion protection
  3. Your project will be more sustainable using non-magnetic steel, which has a lower CO² footprint
  4. With Bekaert’s solution, you are also protecting the marine environment as our armouring wire reduces the surrounding temperature of the cable

Bezinox® solution

Bezinox® non-magnetic armouring wire is a heavily galvanised, austenitic stainless-steel wire that protects three-phase submarine power cables.

Galvanised stainless steel has significant benefits, with non-magnetic behaviour being the most important. Stainless steel has a low permeability, which reduces energy losses in the armouring by the cable’s magnetic field. Consequently, this property significantly increases the cable’s efficiency without interfering with the cable design, as with other armouring solutions.

A heavy zinc layer on austenitic steel offers excellent resistance to pitting and crevice corrosion – perfect for marine applications. Even when the zinc layer gets damaged, the surrounding zinc will act as a sacrificial anode and protect the underlying stainless steel. Combining these features provides a much more predictable and reliable coating lifetime and performance than uncoated stainless-steel solutions, making Bezinox® armouring wire ideal for all your submarine power cables.
