Bus Bar Supports

Keep high-current systems safe, stable, and serviceable with engineered bus bar supports machined from premium thermoset laminates.

Reliability without Compromise

Bus bar supports are electrically insulating components that secure and space copper or aluminum busbars inside switchgear, control panels, UPS systems, and transformer assemblies. They maintain alignment under vibration and fault forces, reduce arcing risk, and extend system life.

Why Atlas Fibre for Custom Bus Bar Supports?

Engineer-grade materials: Epoxy-glass (FR-4/G-10), polyester-glass (GPO-3), and phenolic grades chosen for dielectric strength, heat resistance, and mechanical stiffness.

Tight-tolerance machining: Clean edges, true faces, and consistent hole patterns for drop-in assembly.

Reliable lead times & pricing: North American capacity and disciplined quality controls keep projects on schedule and on budget.

Repeatable outcomes: From protos to repeat runs, our process ensures your next batch performs exactly like the first.

Typical Components We Produce

Standoff blocks, post insulators, and multi-pole spacers
Slotted or countersunk mounting, threaded inserts, keyways
Radiused edges and chamfers to reduce corona and wear
Custom geometries for phase spacing, creepage, and clearance targets

Material Options We Work With (and Supply)

GPO-3 (polyester-glass): Strong arc/track resistance, ideal for switchgear enclosures
FR-4 / G-10 (epoxy-glass): High mechanical strength and dielectric performance
Phenolic (paper/linen/cotton): Cost-effective where toughness and machinability matter

The Data We Machine Toward

Dielectric strength and CTI requirements

Creepage & clearance distances

Short-circuit mechanical loads and thermal rise

UL/NEMA grade selection and thickness availability
