The shanks of the bushings have petticoats in order to meet their ratings where AIR to AIR applications are required. They will have semi-conductive glazing where higher voltage ratings apply.A solid copper conductor is mounted through the center of the bushing, sized depending on the current rating required. The conductor is held in place by Aluminum end caps at the top and bottom. Each conductor is provided with standard threads at the top and with a 2-hole lattened spade at the bottom.H-J Enterprises also manufactures a variety of terminals that will mount to a threaded stud, which are based on the external cable mounting preferences of the unit. Bushing Installation The bushing mounts to the tank by means of a two-piece Aluminum clamp. ½” studs must be welded around a 7 ½” bolt circle to accommodate the clamp. The gasket is then installed over the bushing shank onto the bushing gasket surface. The bushing assembly is then installed through the tank hole and the clamps placed over the studs against the shoulder lange of the bushing.
