Overview

The ABB USK 350-18 DS is a 2-pole aluminum mechanical splice designed for 350 kcmil to #6 AWG copper or aluminum conductors. Rated for 350 A continuous current, this splice provides a reliable, maintenance-free connection in industrial and utility applications. The 18-inch length accommodates standard installation clearances, while the double-screw design ensures consistent mechanical pressure and low-resistance joints. Each kit includes a repair splice cover, four stainless steel screws, two insulating rockets, and a grease packet for corrosion protection and long-term performance. The aluminum construction resists galvanic corrosion when used with aluminum conductors, making it ideal for power distribution, substations, and renewable energy systems. Compatible with both copper and aluminum conductors, this splice eliminates the need for specialized tools or crimping equipment, reducing installation time by up to 60% compared to traditional methods. The included insulating rockets prevent accidental short circuits during installation, and the repair cover provides additional mechanical protection against environmental contaminants. Suitable for indoor and outdoor use in temperatures ranging from -40°C to 90°C, this splice meets industry standards for mechanical integrity and electrical continuity.
