Overview

The ABB Type CU4 Copper Splice is a long-barrel splice designed for medium-voltage applications up to 35kV. This splice accommodates 4 AWG copper wire, making it suitable for power distribution, substation connections, and industrial wiring where reliable conductivity and mechanical strength are critical. The 1-3/4 inch length provides ample contact area for secure crimping, reducing the risk of pull-out or poor conductivity. Tin plating ensures corrosion resistance in harsh environments, extending service life in outdoor or chemically aggressive settings. The gray die color code aligns with industry standards for 4 AWG splices, simplifying identification and inventory management. Unlike short-barrel splices, the extended barrel design distributes mechanical stress more evenly, lowering the risk of conductor damage during installation or operation. This splice is not intended for aluminum conductors or applications exceeding 35kV. For compliance, verify local electrical codes and conductor compatibility before installation.
