Secondary circuits and Busbars
Comprehensive solutions for current-carrying systems and customised Busbars.
Brar specialises in providing customised and comprehensive solutions for high-current management through the design and production of secondary circuits and current-carrying systems.
Our systems, made from high-conductivity copper and aluminium, cater to a wide range of industrial applications, addressing the specific needs of each sector, including energy transmission, nuclear, electroplating, steelmaking, automation, and more.
Brar stands out for its ability to deliver "turnkey" systems, covering every stage of the project, from design and production to assembly, on-site installation, and post-sales technical support.
This integrated approach enables us to provide customised solutions for each client, ensuring precise installation and long-term optimal performance.
We have delivered hundreds of secondary systems and busbars for EAF, LF, and Stirrer furnaces operating on AC and DC currents worldwide.
With our extensive experience and the use of advanced technologies, we design and produce secondary circuits that address the most complex technical challenges while maintaining high operational efficiency.
Our customer service team is always available to provide prompt support for any technical assistance requests. We are ready to design customised solutions tailored to the specific needs of each system, ensuring the highest level of reliability and durability.
Every project delivered by Brar is based on precise technical specifications, enabling us to guarantee maximum reliability and high performance in every application:
- 3D mechanical and structural design: We use advanced 3D design tools to create tailored solutions, optimising the layout and arrangement of systems to ensure maximum efficiency.
- Electrical design and reactance and asymmetry calculations: We conduct in-depth analysis to calculate system reactance and asymmetry, ensuring optimal current distribution and minimising energy losses.
- Water-cooled conductors: The conductors in our secondary circuits are made of high-conductivity Se-Cu copper tubes, water-cooled to maintain optimal operating temperatures and improve long-term reliability.
- Connection plates or clamps for copper cables and flexibles: We design secure and stable connections using plates or clamps, ensuring efficient energy transmission and easy connection to Se-Cu copper cables and flexibles.
- Water-cooled non-magnetic steel support structures: The support structures in our systems are made of non-magnetic steel, offering enhanced mechanical strength and protection against electromagnetic interference, while maintaining appropriate temperatures through water cooling.
- Supports and insulating materials: We use high-quality insulating materials to ensure reliable protection against current leakage, enhancing system safety and durability.
- Flexible cooling circuit tubes: Brar's flexible tubes ensure effective cooling and contribute to maintaining consistent performance across the entire system, extending the operational life of components.
- Flexible transformer connections: We design and manufacture highly reliable flexible connections that accommodate structural movements and thermal expansion, ensuring a secure link between the transformer and the secondary circuit.
- Pre-assembly and testing at Brar: Every system is pre-assembled and tested at our facilities to ensure compliance with technical specifications and enable quick and seamless on-site installation.
- On-site supervision and assembly: Our team of experts provides on-site supervision to ensure proper installation, guaranteeing optimal performance and smooth operation.
With decades of experience in the design and production of high-current systems, Brar is the ideal partner for companies seeking customised, reliable, and high-performance solutions.
Our tailor-made secondary circuits represent excellence in high-current management, ensuring efficiency, reliability, and sustainability across all industrial applications.
