Checon LLC — Booth UL239 (DISTRIBUTECH 2026)
Checon engineers copper and aluminum bus bars—rigid and insulated —with integrated silver contacts and silver (ultra-low contact resistance) and tin (corrosion-resistant joints) plating for high-current power distribution, and power disconnect, transformer disconnect, and automatic transfer switch applications.
Why it matters :
Scalable & flexible: Built to pair with busbar trunking and switchgear for quick reconfiguration and tap-offs as loads grow.
Efficient: High-conductivity Cu options minimize I²R losses/voltage drop; Al variants meet ampacity at lower weight and cost.
Reliable: Silvered interfaces and insulated assemblies support predictable temperature performance and short-circuit withstand when designed into compliant systems.
Core products & options:
Rigid, insulated bus bars (Cu/Al): precision-machined sized for high current in tight footprints.
Integrated silver contact fabrications and plating: silver for ultra-low milliohm contact resistance and heat shedding; tin for durable, cost-effective bolted connections.
Value add: punched patterns, studs/PEMs, insulation/over-molding, and labeling,
How we help design teams:
Checon collaborates on metal selection (Cu/Al), thickness, silver contact integration, joint design, and plating plan. We tune geometry for temperature rise, magnetic forces, creepage/clearance, and torque, then prototype quickly. Our vertically integrated North American facilities handle machining, contact assembly fabrication, precision plating, and finishing for consistent quality and dependable lead times.
Copper vs. Aluminum:
Copper: best for peak current density, tight voltage-drop budgets, maximum thermal headroom.
Aluminum: best for weight/cost advantages—engineered cross-sections achieve required ampacity.
In both cases, silver at contact points reduces resistance and heat; tin protects broad joint areas.
Where this fits:
Utilities/industry: substations, switchgear, reclosers, motor control, and high-cycle DC links.
