Why This Family

Engineered for power conversion circuits

Key characteristics of this product family.

  • Low stray inductance for fast switching circuits
  • Full edge sealing for high-voltage creepage requirements
  • Tin-plated C11000 conductors for corrosion resistance
  • Dielectric selected by voltage class and temperature
  • Tooled, repeatable geometry — no assembly variation
  • Factory-direct with DFM review before tooling

Product Overview

About this busbar family

Electrostatic epoxy powder coating applies a continuous dielectric skin over formed busbars and connectors — the right answer for irregular shapes that films cannot wrap. The cured layer is flame- and moisture-resistant and delivers the insulation where clearance distances are tight, with bare or plated ends masked for bolted connections.

FAQ

Frequently asked questions

Straight answers from the engineering team.

Can you provide documentation for our quality system?
Dimensional and electrical test records are maintained per lot. If your quality system requires CoCs, specific formats or PPAP-style documentation, tell us at quotation stage and we align the paperwork with your requirements.
What current ratings can SHANYUAN busbars handle?
Rating is designed per application up to roughly 1000 A, sized against continuous and peak current with thermal margin — see our ampacity chart for the starting reference points.
Do you support low-volume prototypes before production?
Yes. Custom projects typically run: spec review, DFM, quotation, sample build for fit and electrical verification, then tooled production with documented QC per lot.
How long does a sample build take?
A sample is typically produced within 5–7 working days from drawing approval. Fit and electrical verification is done in-house, and you receive test results together with the sample.
What quality system do you follow?
Production follows a documented process chain with batch records: incoming material checks, dimensional inspection, hipot and insulation testing, continuity checks and final visual inspection. Test records are issued per lot on request.
Do you offer warranty on your busbars?
Yes. Parts are covered against material and workmanship defects for the agreed warranty period stated in the purchase agreement. Any non-conforming parts are reworked or replaced, with failure analysis shared on request.
