The WCJC Brass Jointing Clamp provides a reliable and durable solution for connecting cables to electrical equipment and indoor distribution systems. It ensures secure, low-resistance connections and can be reused, making it practical and cost-effective for both initial installation and maintenance work.
The WCJC clamp is made of solid brass with a nickel-plated surface that improves corrosion resistance and conductivity while maintaining a clean, durable finish. The bolt-fixed structure guarantees a tight mechanical and electrical connection between the cable and busbar or equipment. Designed for repeated use, it can be removed and reinstalled without loss of performance. The available sizes cover a wide range: WCJC-1 (16 sq mm), WCJC-2 (25–35 sq mm), WCJC-3 (50–70 sq mm), WCJC-4 (120–150 sq mm), WCJC-5 (210–250 sq mm), WCJC-6 (300 sq mm), and WCJC-7 (400–500 sq mm).
Using the WCJC Brass Jointing Clamp ensures a strong, bolt-fixed joint that resists loosening and maintains stable electrical contact. The nickel-plated brass body minimizes oxidation and withstands environmental factors in control rooms or electrical panels. Its design supports multiple conductor sizes, enabling versatile use in switchgear, distribution panels, and auxiliary connections. The simple bolt-mounting system allows fast installation and easy maintenance without specialized tools.
The WCJC Brass Jointing Clamp is ideal for indoor distribution systems, equipment cabinets, switch rooms, and panel boards. It performs well in both new installations and retrofits. Its reusable nature and wide compatibility make it perfect for facilities that often modify or upgrade layouts. With one clamp type fitting many conductor ranges, installers reduce inventory and achieve efficient procurement.
