Earthing & Grounding Systems
Importers in Kisumu

There's no set minimum on the international side. Earthing material is usually bundled with cable tray, busbar or gratings inside one container, since that spreads freight cost across the whole order. Tell us your destination port and Incoterm and we'll work out the most economical shipment size.

Standard rods, plates and strip typically ship in 3 to 5 weeks from order confirmation for a full container; smaller consolidated orders can move faster. Custom lengths, non-standard copper thickness or large chemical-earthing quantities push the schedule out, so flag those needs before you lock in a project date.

Coastal, humid and high-chloride sites should specify copper-bonded rod at 450 microns minimum or solid copper, with stainless steel or copper couplings. Never carbon steel; it creates a galvanic cell at the joint. Desert sites with low chloride but high resistivity soil often do well with GI pipe electrodes and a bentonite backfill compound to bring resistance down.

Flat strip has lower inductance per unit length at the high frequencies generated by lightning impulse and high-speed fault current, that makes it better for LPS down-conductors, substation earth grid loops and any run where the path inductance affects current distribution. Stranded wire is more flexible and routes through conduit or cable tray more easily, it suits equipment bonding tails (transformer body, motor frames, panel boxes). Most substation and outdoor industrial earthing uses both: flat strip for the buried grid and main down-conductors, stranded tinned copper for the equipment connection tails.
