1.2 kV 600A Tri-Clamp Secondary Bushing
Reliable Low Voltage Interface for Transformer Secondary Connections
Cooper Power Systems Secondary Bushings are designed for external mounting on distribution transformers filled with transformer oil, R-Temp®, Envirotemp® FR3™ Fluid or an approved equivalent and are available with either spade or stud connections. They are designed for use indoors or inside cubicles of fluid-filled transformers or switchgear. Internal spade/externally threaded stud secondary Tri-Clamp bushings are available with 5/8" and 1" diameter copper studs. An internally threaded stud option is also available. The 5/8" and 1" bushings come standard with 1 3/4" of usable external threads. The 1" bushing is also available with up to 3" externally usable thread lengths. Industry standard mounting configura[1]tion and compatibility with most available connectors allow use in a wide range of applications.




Installation
Clamping studs must be welded around the 1 7/8" hole to accommodate the clamp. The gasket is installed over the bushing shank onto the bushing gasket surface. The bushing assembly is installed through the tank hole and is placed over the studs against the shoulder flange of the bushing. A plated lockwasher and nut are installed on each stud and tightened to the recommended torque. Refer to installation instructions.
Note: Mounting nut and washer to match mounting stud. Maximum torque 40 to 60 In-Lbs.
