Abstract
An inventive pressurized cable is provided that simultaneously provides electrical connections and a supply of air, gas, or vacuum to an electromechanical device utilizing an existing connection on the device. The use of an existing cable connection for the supply of air or gas to provide positive pressure or a vacuum condition to an electromechanical enclosure allows for the use of standard electromechanical components without alteration and potential voiding of existing warranties. The present invention finds particular utility in the field of industrial automation where motors are subjected to coolant liquids and other types of contaminants that tend to infiltrate the motor seals, especially when the motor is shut down which causes a negative pressure inside the motor case that draws moisture in. Reactive gasses may be introduced with the inventive positive pressure cable that act to neutralize or condition harmful pollutants generated by the motor such as ozone.
