Are you sure that it is delta double delta? I would have expected delta double star!

Yes that is correct, the manufacturers literature gives the following information. Low speed has line connection to U1, V1 & W1 with U1 - W2, V1 - U2 & W1 - V2 linked. In high speed, line is connected to centre tappings U3, V3 & W3 with U3 - W1 - W2, V3 - U1 - U2 & W3 - V1 - V2 all linked. Never come across one of these before. Any ideas.
