Busbars for Kenya projects, made in India

Our mainstream export product is solid flat copper busbar, cut and formed to drawing, and that covers the large majority of switchgear, panel and substation requirements. Flexible laminated busbar, thin copper foils built for vibration-tolerant connections, is a specialised product. Tell us your specific requirement and we can confirm whether a solid busbar with a flexible jumper section meets the same need.

Copper carries roughly 1.6 times the current of aluminium for the same cross-section and holds up better through repeated jointing, which is why it's the default for compact panels, data centres and anywhere space is tight. Aluminium is lighter and cheaper per unit of conductivity, and it works well where space isn't constrained and joints are torqued and maintained properly. The catch: it needs larger cross-sections and more careful joint design to avoid the oxide-layer and creep problems aluminium connections are known for.

HS 7407 covers copper bars, rods and profiles, the classification for solid busbar. HS 7409 covers copper plates, sheets and strip, thinner, flat-rolled copper products. Busbar cut from bar or profile stock is generally 7407; if yours is cut from rolled sheet or strip stock, 7409 may apply instead. Check with your customs broker based on the actual manufacturing process used.

Solar string and combiner cabinets often run at 1500 V DC, the busbar insulation system, creepage distances and clearance need to match. We supply busbars with the appropriate stand-off and sleeve for 1500 V DC service, sized for the array's short-circuit current.
