COMPRESSION CONNECTORS

600V

TYPE SPT Shrouded Aluminum Pin Terminals • Shroud accepts insulation of conductors. • Tinned copper rod factory crimped into an aluminum compression sleeve. Cavities are pre-filled with electrical joint compound and capped. • Pin terminals are widely used in clamp-type plated bronze connectors, common to pole-type transformers, disconnect switches, cutouts and lightning arrestors, to allow aluminum conductors to be connected. The transition from copper to aluminum is made within a sealed compression joint to assure protection from bi-metallic corrosion.
