Copper Core Flange Bushing

VTE has developed an innovative and unique solution for passing current through a barrier. Our Copper Core Flange Bushing brings new features, low cost and ease of use to yoru current passing applications.

Our Copper Core Flange Bushings have been designed with these key components in mind:

  • High Energy Transfer
  • High Torque
  • High Anti-Rotation
  • Multiple Weatherproof Options
  • Low Production Cost
  • Small Insulated Footprint
  • Also available in Metric 10mm
High Energy Transfer
The Copper Core is cold swaged into a hex shape, providing high energy transfer performance. The conductive materials are placed exactly where needed, reducing cost and improving performance.
High Torque
Significant amounts of fastener torque is required when attaching multiple 4/0 ga (120mm2) cables. Brass shaft devices may fail under high torque loads. Our Copper Core Power Bushing uses a 2/8" (or 10mm) Nickel-plated steel shaft to provide high torque value.
High Anti-Rotation
Four mounting holes ensure secure mounting for anti-rotation. Bushing can use round or double-d hole for added anti-rotation and legacy applications. Inner copper core and shaft are swaged into a hex shape and inserted warm, to ensure tight fitting and high anti-rotation, providing 100% stability when fastening cables.
Multiple Weatherproof Options
Our CCFB can be ordered with a weatherproof gasket, as well as 232 Series Terminal Insulators. The insulators snap onto the groove ring to prevent accidental shorting, as well as weather resistance to IP65. Both sides of bushing can be insulated.
