Low loss energy saving
Compared to cables, copper bars have lower impedance, and the loss is reduced by 30%+ under high current (1000A+) conditions, saving electricity costs over the long term; large heat dissipation area, no need for additional fans, higher reliability
Anti-vibration + strong rigidity
Hard copper bars are fixed installation, no loosening during long-term operation of the machine room / UPS start-stop impact, suitable for static high current scenarios; combined with insulators, avoid cabinet grounding
Installation efficiency
Factory prefabrication, direct bolt fixation on site, 50% shorter installation time compared to cable wiring.
Q
What copper material is used for these busbars, and what is the purity level?
A
Our copper busbars are manufactured using high-purity electrolytic copper (C11000 / T2 grade), with a copper content of ≥99.9%. This ensures excellent electrical conductivity (≥58 MS/m) and superior thermal performance suitable for high-current UPS applications.
Q
Can the copper busbars be fully customized in terms of size, hole pattern, and bending shape?
A
Yes, all busbars are fully customizable. We support custom width, thickness, length, hole positions (M6/M8/M10/M12), bending angles, and surface treatments. Simply provide your cabinet drawings or technical specifications and we will manufacture accordingly.
Q
What insulation options are available, and which is recommended for high-voltage UPS systems?
A
We offer heat shrink tubing, epoxy coating, segmented insulation with bushings, and overall epoxy with insulator fixation. For high-power UPS systems (200–300 kVA and above), we recommend overall epoxy coating combined with insulator fixation to ensure 2500V AC withstand voltage compliance.
Q
What is the minimum order quantity (MOQ) and what is the typical lead time?
A
The MOQ depends on the specification and customization requirements. Standard sizes typically have a low MOQ. For fully customized orders, lead time is generally 7–15 business days after drawing confirmation. Please contact us directly for a precise quote and timeline.
Q
How are the copper busbars packaged for shipping to prevent damage during transit?
A
Each busbar is individually wrapped with protective film, then packed in reinforced cartons or wooden crates depending on length and quantity. Anti-rust treatment and moisture-proof packaging are applied as standard to ensure the product arrives in perfect condition regardless of shipping distance.
Q
Are these copper busbars compliant with international standards for UPS and power distribution systems?
A
Yes. Our copper busbars meet relevant IEC and GB standards for low-voltage power distribution equipment. The insulation withstand voltage is tested at 2500V AC for 1 minute without breakdown, complying with low-voltage power distribution safety requirements for data centers and industrial UPS installations.
