ABSTRACT:
A flexible, gas tight electrical coupling for a gas cooled electrodynamic system such as an electrical generator includes a first connector element that is in communication with a first combined coolant and electrical path and has a first passage defined therein for a coolant, a second connector element that is in communication with a second combined coolant and electrical path and has a second passage defined therein for the coolant, a flexible tube for communicating the first passage in the first connector element with the second passage in the second connector element, and an electrical connection for electrically connecting the first connector element to the second connector element. According to one aspect of the invention, the electrical connection is external to the flexible tube, resulting in cost savings and other advantages when compared to an internal electrical connection. According to a second aspect of the invention, an outside of the flexible tube is sealed to the first and second connector elements to effectively guard against leakage of the coolant.
