Abstract: A separable splice connector which is particularly suitable for 15/25 kV, 600 ampere primary distribution system cables is disclosed. The connector includes a unitary splice body assembly of molded elastomeric material having a longitudinal portion for receiving lug conductor terminated adjacent cable ends thereon, and a transverse portion for receiving removable threaded fastening means which function to secure the lug conductors together within the splice body. The fastening means also provides interface or adapter means for external interchangeable components. Accordingly, the connector provides a separable straight splice of the cables and standard 600 ampere interfaces for transformer bushings, connector plugs, test point plugs, reducing plugs, and the like.
