The Color-Keyed Advantage: Simplicity Meets Precision
The Color-Keyed compression connector system revolutionized the electrical industry with its innovative color-coding method. This foolproof system matches the right connector to the correct tool and die, eliminating installation errors and helping ensure consistent, reliable crimps every time. The color bands provide instant visual verification, while the hex-style crimp embosses the die code directly onto the connector for permanent installation confirmation.
Color-Keyed compression lugs and connectors deliver proven electrical performance with excellent pull-out strength and low resistance. Available for both copper and aluminum conductors, the system includes lugs, splices, taps and grounding connectors. The die index stamped on each connector helps ensure proper tool selection, while the color-coded bands make it easy to identify the right connector for each application. This industry-standard method has become the preferred choice for power cable connections in commercial, industrial and utility installations.
Complete Solutions for Every Connection Challenge
From overhead distribution to underground applications, Blackburn and Color-Keyed products provide comprehensive connectivity solutions for the entire electrical grid.
Whether you need non-insulated butt splice connectors for low-voltage applications or heavy-duty compression connectors for high-voltage transmission lines, ABB offers the right solution. The integration of Blackburn mechanical expertise with Color-Keyed compression technology helps ensure installers have access to reliable, code-compliant products that streamline installation and deliver lasting performance. Every product is engineered to meet or exceed industry standards, backed by ABB's commitment to quality and innovation.
