What is a Busbar?

A laminated busbar is a multilayer construction of conductors: copper or aluminum separated by thin dielectric materials, laminated in one structure. Electrically, it is a multilayer electrical circuit that distributes the electrical current from capacitors (buffer) to power modules (IGBT) through specific connections.

Busbar Roles in Power Applications

Busbars are metal bars designed for carrying large amounts of current. Often made of copper or aluminum, every home electrical panel has busbars to distribute ac power to the rows of circuit breakers. Busbars are engineered for power distribution. They are made of copper or aluminum layers separated by insulating materials and laminated into a single structure. Designers choose ROLINX busbars for the quality and reliability, electrical and mechanical expertise, co-engineering and flexible lead times and wide applications to high-power markets, including EV/HEV, rail and renewable energy. They are used in the most demanding applications including mass transit and electric propulsion, industrial drives, renewable energy and automotive systems.

Why Choose ROLINX Busbars?

ROLINX busbars are constructed and manufactured laminated busbars that meet the strictest requirements for railway drive converters, network, wind and solar converters, as well as drives for industrial applications. They have a low inductance, controlled partial discharge, high current capacities and compactness.
