flexible insulated bus bar header

Flexible Insulated Copper Bus bar

Features:

  • Thin layers of tinned electrolytic copper formed into a stack
  • Insulated by high-resistance, self-extinguishing PVC with less than 20% contact with conductor for high flexibility
  • Easily bent, folded, and twisted, improving assembly flexibility, shortening connections, and decreasing footprint
  • Dramatically smaller and more flexible than comparable cable based on ampacity
  • Better power density than cable with lower skin effect ratio
  • Connections made by punching and bolting directly through the copper laminates, clamping onto the end of the flexible bar
  • No lugs needed, reducing installation time and improving resistance to vibration
  • Weight savings and material savings compared to wire alternatives
  • Reduces total installation cost
  • Traceability codes and designation part numbers printed on insulation
  • 100% production dielectric tested
  • UL 758 Appliance Wiring Material requirements for Cold Bend testing at -40°C and -50°C (-40°F and -58°F)
  • EAC & RoHS compliant

IMPORTANT! Storm can also drill or punch holes, form (bend and shape) and custom-cut flexible bar to any size you need. *Lead times may apply.
