duresca bus duct
(OP)
hello, has everyone come across this type of bus duct? any information i can get? This busduct has been proposed to an offshore wind farm main transformer rated at 150/33kV. HV primary connection we use gas insulated busbar and LV connection is the duresca bus duct. I'm wondering what are the advantages of using duresca bus duct than cables?
Your info will be greatly appreciated. Many thanks in advance.

It's a really good product, something special.
I don't work for them
Advantages, you don't need few condactors per phase, special isolation. I know projects with this bus duct 20 years in operation w/o faults.
Good choice.
Best Regards.

What is the distance between the transformer and 33kV switchgear?

The water tree and the partial discharge properties are better than in a XLPE insulated cable. But there are many appurtenances supplied only by MGC as terminating, bends, connectors and other. As the system is rigid even is very well insulated and protected needs a clear routing and use of a usual cable tray is almost impossible. The wall penetration is also a MCG piece. But it is a system good for long time. Cable is more flexible there are many manufacturers for accessories and may be laid easy. See more information here:

MGC has an original design calculation way [you may order the design with the package, I suppose].

When going from inside a building to outside flexible braided coupling joints are used at the ends to allow for expansion and contraction.
The product has been around for at least 30 years and primarily spec'd in Europe.
