Overview

The ABB TR64 is a 4-1/4 inch aluminum service entrance compression splice designed for secure, long-lasting connections of aluminum conductors in service entrance applications. This splice accommodates 2 ASCR (Aluminum Conductor Steel Reinforced) wires and 2 stranded aluminum wires, with a conductor diameter range of 0.292" to 0.316". The TR64 is pre-filled with oxide inhibitor to prevent oxidation and moisture ingress, ensuring reliable electrical contact and corrosion resistance over time. Red caps are included for protection during handling and installation. The splice features solid center barriers and large chamfers for easy cable insertion, with color-coded design for quick identification. Installation requires specific dies (5/8, TU, 8A, 243, 52) and a hydraulic tool for proper crimping. The TR64 complies with ANSI C119.4 standards when installed on aluminum-to-aluminum or aluminum-to-copper conductors, making it suitable for commercial and industrial service entrance applications. This splice is a critical component for establishing durable electrical connections in power distribution systems where aluminum conductors are specified. The splice's design ensures consistent crimp integrity, reducing the risk of loose connections or electrical faults. Its robust construction and pre-applied oxide inhibitor enhance longevity, making it ideal for outdoor and underground installations where environmental resistance is critical. The included red caps provide visual indication of proper installation and additional protection against contaminants during storage and transport.
