Overview

ABB MS 20 Aluminum Full-Tension Compression Splices are designed for reliable, high-strength connections of 2/0 AAC (All-Aluminum Conductor), 2/0 ACSR (Aluminum Conductor Steel-Reinforced, 6/1 strand), and 2/0 AAAC (All-Aluminum Alloy Conductor). This splice ensures full-tension performance, maintaining conductor integrity under load while providing a permanent, low-resistance joint. The 17-7/8 inch length accommodates standard compression tooling, including ABB dies TM 62 and 11/16 inch. These splices are manufactured from high-conductivity aluminum alloy, ensuring minimal electrical resistance and long-term reliability in overhead transmission and distribution applications. The compression design eliminates the need for complex crimping patterns, simplifying installation while ensuring consistent performance. Suitable for use in utility, substation, and industrial power systems where conductor continuity and mechanical strength are critical. Compatible with standard compression tools and dies, the MS 20 splice reduces installation time compared to traditional methods like bolted connectors or soldered joints. Its full-tension rating ensures compliance with ANSI C119.4 and other industry standards for conductor splicing. Ideal for utilities and contractors requiring durable, field-proven solutions for medium-voltage conductor systems.

Special Features
Prefilled with Oxide Inhibitor to prevent oxidation and keep out moisture. Simplify hot line distribution construction and eliminate the separate splicing of ACSR core wires. Constructed from seamless Aluminum tubing, provides high conductivity. Sleeves have an internal taper that acts as a funnel-lie entrance for easy insertion of conductors and provides stress relief onthe conductor strans upon compression. Solid Barriers in the center of the sleeves ensure all-around distribution and penetration of the oxide inhibitor to all strands
