Precision-machined from high-grade brass alloy, this lug combines excellent electrical conductivity with superior mechanical strength, making it ideal for critical power transmission infrastructure. Unlike copper or aluminum alternatives, the WCJC Brass Lug offers enhanced corrosion resistance and thread durability, particularly valuable in outdoor and industrial environments. Available in sizes ranging from 16 mm² to 240 mm², it provides versatile termination solutions for diverse conductor sizes in transmission and distribution networks.
Constructed from CW617N brass alloy (CuZn37Pb2), the lug achieves a conductivity rating of ≥65% IACS (International Annealed Copper Standard), ensuring efficient current transfer with minimal power loss. The brass material naturally resists tarnishing and corrosion, even in high-humidity or polluted environments.
Each lug undergoes precision machining to create smooth conductor entry points and uniform bolt holes, reducing installation time and ensuring consistent performance. The surface features a nickel-plated finish (5-8 µm thickness) that enhances corrosion resistance and provides a low-friction interface for repeated bolt tightening.
Designed to withstand mechanical stress from thermal cycling and vibration, the WCJC Brass Lug maintains stable connections with tensile strength exceeding 300 MPa. Its robust construction supports torque values up to 45 Nm for bolted connections, preventing loosening under dynamic load conditions.
In electrical substations, the WCJC Brass Lug terminates aluminum and copper conductors in busbar systems, circuit breakers, and transformer bushings. Its high current-carrying capacity (up to 600A for 240 mm² size) makes it suitable for substation feeder circuits.
Heavy industries such as steel manufacturing, chemical processing, and mining utilize these lugs for connecting power cables to switchgear, motor starters, and heavy machinery. Their resistance to industrial contaminants ensures reliable performance in harsh environments.
The lug plays a critical role in railway power systems, terminating conductors in overhead catenary systems, traction substations, and rail vehicle electrical systems. Its vibration resistance makes it ideal for the dynamic conditions of railway operations.
The lugs accommodate both stranded and solid copper conductors, as well as aluminum conductors when properly treated with anti-oxidation compounds. Their universal design works with circular, sector-shaped, and compact conductors within the specified cross-sectional range.
Brass offers superior mechanical strength and corrosion resistance compared to copper, making it better suited for outdoor installations and applications requiring repeated disconnections. While copper has slightly higher conductivity (~97% IACS vs. brass’s ~65% IACS), brass lugs provide sufficient conductivity for most power transmission applications at a competitive price point.
Periodic visual inspections are recommended to check for loose connections or corrosion, typically every 2-3 years in indoor environments and annually in outdoor or industrial settings. Clean connections with a dry cloth if necessary, and re-torque bolts to specified values if signs of loosening are detected.
Yes, the lugs are designed for installation with standard crimping tools and torque wrenches. Consult the product datasheet for specific crimp die sizes and torque values corresponding to each conductor size to ensure proper installation.
