Compression lugs are electrical connectors manufactured from high-quality copper or aluminum, often with electro-tin plating to enhance performance. They accommodate cable sizes from 2 American Wire Gauge (AWG) to 3/0 AWG and are rated for voltages from 600 V to 35 kV, depending on proper installation and insulation techniques. The high-grade materials minimize resistance, reducing energy loss and improving system efficiency.
The durable construction offers resistance to corrosion, wear, and harsh environmental conditions, contributing to longevity in demanding settings. Precise dimensions and features like chamfered barrels or sight holes allow for secure fit, simplifying installation and reducing labor costs. This makes them cost-effective for applications ranging from small-scale projects to large industrial systems.
Compression lugs support flexible and stranded copper conductors, with stud sizes typically ranging from 1/4 inch to 1/2 inch. Barrel lengths are available in standard or long configurations, while tongue sizes and barrel diameters vary to match specific mounting requirements. Temperature ratings often reach 90 degrees Celsius, and color-coding or die indices enable easy identification during installation, ensuring compliance with industry standards for safety and performance.
