Overview

ABB PAC345 Aluminum Parallel Groove Clamp with Cast Copper Liner: Electrical connector for parallel conductor applications in medium-voltage power distribution systems. Supports main conductor sizes 1/0 to 8 AWG ASCR (Aluminum Conductor Steel Reinforced) and tap conductor sizes 1/0 to 8 AWG ASCR. Constructed from heat-treated cast aluminum alloy with pressure-cast body for moisture sealing and corrosion resistance. Integrated cast copper liner provides high electrical conductivity and thermal performance, reducing hotspot risks and galvanic corrosion between dissimilar metals. Parallel groove design ensures secure, vibration-resistant connections with simplified installation. Includes galvanized steel carriage bolt, nut, and lockwasher. Dual-rated for aluminum, ACSR, and copper conductors. Compact design for easy integration without extensive modifications. Applications: overhead line taps, transformer connections, distribution system upgrades. Key dimensions: clamp length 2 15/32 in., width 1 3/4 in., height 9/16 in., bolt size 3/8 in. Pressure-cast aluminum body: width 3/8 in., height 9/16 in. Copper liner ensures optimal contact with conductor diameters: main/tap conductors 0.398 in. (max) to 0.128 in. (min). Available prefilled with oxide inhibitor for additional corrosion protection on copper-to-aluminum connections, ideal for harsh or high-moisture environments.
