Abstract: An improved cable system and method for an electricity generating windmill having a base formed from a plurality of stacked base sections is provided. Each base section includes a bundle of both power and control cables which are alignable with one another when the base sections are stacked and assembled. Mating electrical connectors which may be easily interlocked are provided at the ends of the power and control cables, and in the terminals of the generator and inverter of the windmill. In the preferred embodiment, bayonet-type connectors are used to provide a secure, interlocking coupling between adjacent cable ends with a minimum amount of twisting motion between the cables, which are necessarily of heavy gauge to conduct the current produced by the generator. The system greatly facilitates installation of the cable system as well as repair or replacement of damaged or worn cables during the lifetime of the windmill.
