Engineers are tasked to design a lamination that locates, shapes and routes conducting points in ways to ensure that the multi-layered current can flow in opposite directions and in equal strength. The key aspect of this design is to generate opposing voltages proportional to the rate of current change in a circuit, which in turn enables the opposing magnetic fields to cancel each other's ticket, eliminating a free ride for extra inductance.

With the guidance of a competent fabricator, designers and engineers are able to make the right choice in insulating material and conductor (raw or plated copper) thickness. Generally, the rule of thumb is to make sure the copper metal and dielectric materials are as thin as possible, but this isn't always the case due to environmental demands.

Laminated Bus Bar meets a wide range of applications. • Custom Power Distribution Assemblies • Multi-Layer Laminated Copper Connectors • Multi-Layer Bus Bars • Capacitor and IGBT Structures Storm also goes the extra mile to meet the laminated bus bar needs of OEM customers from industries, including: Telecom, Power Generation, Electromechanical Motor Controls, as well as Aerospace and Military. From design to execution, Storm does its best to engineer laminated bus bar with a smaller profile design and a minimal number of interconnections.		Our design experts work hand in hand with OEM designers and engineers to ensure success. Plus all parts are clearly marked for efficient installation.

Choose from these or a combination of laminated bus bar edge geometries. Each offers a specific cost-effective option to meet environmental and space demands.

Though bus laminations have been around for almost two decades, newer, advanced insulating materials like Kapton and Teonex when combined with improved design and fabrication techniques, not only utilize electric energy more efficiently, but save time and money. Selection of the proper internal dielectric insulations can depend on capacitance, inductance, voltage potentials and operating environment.
