DC Bus Bars for Power Distribution Systems

Rigid copper bus bars, such as prepunched or threaded variants, provide fixed, stable connections ideal for primary and secondary distribution panels. Flexible bus bars, including laminated and copper mesh types, accommodate vibration, misalignment, and construction tolerances, making them suited for movable components, control cabinets, and applications requiring vibration absorption.

Our DC bus bar range covers standard distribution voltages up to 1000 VAC and high-voltage DC applications up to 1500 VDC. Specific products such as the Ultraflexx and Isoflexx® are rated at 1000 VAC / 1500 VDC, while rigid and prepunched copper bars are rated for systems under 1000 VAC.

All bus bars in this range use high-conductivity copper — either solid Cu-ETP for rigid bars or Cu-ETP1 flat copper mesh and layered electrolytic copper for flexible variants. Conductivity is 58 MS/m across copper-based products, ensuring minimal resistive losses and efficient heat dissipation under high-current loads.

Yes. Flexible and laminated bus bars such as the Ultraflexx and Isoflexx® are available in custom lengths, cross-sections, and with services including cutting, bending, twisting, and hole pattern insertion. Rigid copper bars are offered in multiple standard length, height, and thickness configurations to suit diverse panel build requirements.

Yes. Products such as the Ultraflexx flexible busbar and Isoflexx® laminated busbar are specifically designed for control cabinet module connections, risers in switchgear, and connections to transformers and switching devices. They comply with IEC 61439-1 for low-voltage switchgear and control gear assemblies.

For industrial applications, look for UL Listed (UL 508 or UL 758), CE marking, RoHS compliance, and IEC 61439-1 compliance. For railroad or transit environments, DIN EN 45545-2 certification is essential. For North American panel builds, UL 67 compliance is relevant for flexible copper bar installations in electrical panels.
