Is there any electrolytic reaction between aluminium conductors and connecting copper cables etc?
There are no problems concerning the reaction between copper and aluminium, as all aluminium busbars manufactured by Zucchini are electro-tin plated throughout their entire length. This is achieved by first coating the raw aluminium in zinc, then copper and finally tin-plate. This is a proven system which has been used extensively throughout the UK and the rest of the world.
