For protecting wildlife from electrocution by high voltage components, dielectric covers are used to cover fuse cutouts, insulators, or other high voltage components. The cover includes through-holes for receiving retaining pins to secure the cover in place. The holes are the weak link in flashover prevention since the holes form an air gap, which has a breakdown voltage lower than that of the cover material. To prevent a bird's wing or a squirrel's tail from directly covering the hole in the surface of the cover, an arched or tubular hood is formed around each hole to block the bird or squirrel from directly covering the hole, reducing the risk of a flashover through the hole. The hoods extend out about 1-1.5 inches to essentially add a 1-1.5 inch air gap between the animal and the hole without enlarging the cover.

This application is directed to dielectric isolation of fluid conveyance systems both Aerospace and Industrial. The dielectric isolator 5 serves to both prevent high voltage surges transitioning down the conveyance distribution system and second as a means to conduct fluid under pressure. This application address the limitations of current art by approaching the challenge as a pure electrical solution. High resistance precision electrical elements 10 are integrated into a one piece high dielectric material housing 15 which embodies the required end fitting interface. Conductive end collars 20 bonded in position to housing 15 and in contact with resistive elements 10, provides the means for conducting electrical energy to the system interface fitting, coupling or connection. The application provides precision resistance from one unit to the next with built in triple redundancy for high life expectation. The application has the ability to withstand high voltage surge up to 30,000 Volts and by virtue of integrated end ferrules eliminates internal arcing and provides a leak proof design.
