Performance
25kV/35kV 200A Rotatable Feedthru Insert is used to provide dual bushings from a single apparatus bushing well. It makes converting radial-feed transformers to feedthru transformers and adding in-line arrester protection both easy and practical. Its patented, built-in torquelimiting ratchet prevents operators from accidentally breaking bushing well studs during installation. The Loadbreak Elbows are molded with high quality sulfurcured insulating and semi-conducting EPDM rubber, When mated with comparably rated products, the insert provides a fully shielded and submersible load break apparatus connection. The Rotatable Feedthru inserts latch indicator ring, located on the circumference of the bushing’s collar, eliminate the quesswork of loadbreak elbow installation on the bushing interface. The bright yellow ring provides immediate feedback to determine if the elbow is properly installed on the bushing. If the yellow ring is completely covered by the loadbreak elbow, it is fully “latched” if the ring is visible. The elbow can be installed correctly before any problem occur.
