Large lugs were initially being used for wind turbine electrical connections but were found to be costly. Electricians had to be present for all installations and service. Standard circular connectors allowed avoiding hardwiring but had limitations. There was a desire for a quick disconnect connector that could carry high loads and withstand vibration. The Amphenol Industrial Vortex series were the solution, offering quick disconnect with increased amperage through Radsok contacts. The Vortex GT carries 800A through a single 18mm contact and the Vortex Tri-Power carries 750A total through three 10.3mm contacts. These connectors eliminated the need for electricians during service.
