The twist cable connects the wind turbine to its power and control cables, located at the base of
the tower. It consists of a power cable and a control cable and eliminates any problems with the
slip ring assembly as there are no moving parts. If the cable becomes physically twisted, i.e.
more than ten complete turns, it must be disconnected, untwisted and re-connected. Depending
on site conditions, this might have to be done every six months. Rotating connectors can be
purchased from AOC as an option.
The only failures possible in the twist cable are broken connections at either end or a physically
severed cable. The twist cables are suspended from the bottom of the gearbox by the bracket
shown in Figure 12.5-1.
