Integral Web Bus Conductor (IWBC)
Maximum Structural Rigidity for High-Current Substations
Engineered for the demands of modern power distribution, Maverick Metals’ Integral Web Bus Conductor (IWBC) combines exceptional mechanical strength with high-efficiency current ratings. Unlike standard tubular bus, the IWBC features a unique internal web design that reinforces the profile, allowing for longer spans and higher fault-current withstand capabilities without the need for external stiffeners.
Designed to streamline substation architecture, our IWBC eliminates the need for complex spacing components like clamps or welded tie bars, reducing installation time and total system weight while maximizing airflow for natural cooling.
Aluminum Alloy Options
We supply IWBC in high-conductivity and structural aluminum grades to match your specific project requirements.
6061-T6: A structural grade utilized when mechanical strength is the primary priority over maximum conductivity.
6101-T6 (Standard Electrical): The industry standard for bus conductors. It offers the optimal balance of high electrical conductivity (approx. 57% IACS) and mechanical strength.
6063-T6: Known for excellent corrosion resistance and surface finish, often used in exposed outdoor environments.
