Overview

The ABB BWT 15 brass bushing is a high-voltage electrical connector designed for applications exceeding 1000 volts. This hex-shaped bushing measures 1.25 inches in length and 0.75 inches in width, providing a compact yet robust solution for heavy-duty electrical installations. The unit features a thru-tap on top with a 1/2-13 UNC-2B thread and a side thru-tap with a 3/8-16 UNC-2B thread, ensuring compatibility with standard hardware and conduit systems. Included with the BWT 15 is one 3/8-16 x 0.75-inch wide brass nut and one 1/2-20 x 0.75-inch full-threaded stainless steel bolt, eliminating the need for additional fasteners and reducing assembly time. The brass construction offers excellent conductivity and corrosion resistance, making it suitable for both indoor and outdoor applications where durability is critical. Commonly used in industrial power distribution, substations, and high-voltage equipment, the BWT 15 provides a reliable threaded connection for secure electrical bonding. Its hex shape allows for easy installation using standard tools, while the threaded design ensures a tight, vibration-resistant fit. The UNC-2B thread specification guarantees precise engagement with mating components, reducing the risk of loosening under operational stress. This bushing is ideal for systems requiring high-voltage connectivity with measurable reliability, such as utility transformers, switchgear, and renewable energy installations. The inclusion of corrosion-resistant stainless steel hardware further enhances long-term performance in harsh environments. For engineers and technicians specifying components for high-voltage applications, the ABB BWT 15 delivers a proven, spec-compliant solution.
