Richards Straight Receptacle Adapter kits (P625SRA) are used with a 15/25kV 600A bushing to allow installation of a disconnectable joint sleeve. The basic P625SRA kit consists of an EPDM insulated sleeve, an aluminum or copper contact, and a brass bolt. Once the SRA is installed on a bushing interface, a prepared cable assembly can be bolted to the contact as in a disconnectable joint.
