GI Earth Rods with Palm – Reliable Galvanized Earthing Solutions by SG Power
A safe electrical installation starts below the ground. Every building, panel, transformer and machine needs a low-resistance path that carries fault current and lightning surges harmlessly into the earth. GI Earth Rods with Palm from SG Power Products Pvt. Ltd. provide that path. They combine the strength of a steel core, the corrosion protection of galvanizing, and the convenience of a flat palm terminal for quick, secure connections.
As one of the trusted GI Earth Rods with Palm manufacturers and suppliers in India, SG Power designs and produces earthing rods for residential, commercial, industrial, railway, metro, DISCOM and renewable energy projects. Each rod is built to deliver stable grounding performance for many years with minimal maintenance.
What Is a GI Earth Rod with Palm?
A GI (Galvanized Iron) earth rod is a solid steel rod coated with a protective layer of zinc. The zinc coating shields the steel core from moisture, salts and soil chemicals, which slows corrosion and extends the life of the electrode.
The palm is a flat, pre-drilled plate attached to the top of the rod. Instead of wrapping a conductor around the rod or relying on a loose clamp, the installer bolts the earthing strip, cable lug or conductor directly onto the palm. The result is a firm, flat contact surface with a large connection area. This lowers contact resistance and makes inspection and maintenance easier.
SG Power's standard palm design has 10 mm × 4 terminal holes. This allows multiple conductors or strips to be connected to a single electrode, which is useful where panels, equipment bodies and lightning down conductors must all share the same earth pit.
Key Features and Benefits
Strong E250 Steel Core. The rod is made from E250 grade structural steel. This gives it the mechanical strength to be driven into compact or mixed soil without bending or breaking.
Corrosion-Resistant Galvanized Finish. The galvanized layer protects the steel from rust and soil corrosion. This helps the rod keep its conductivity and structural integrity for longer, even in moist or chemically aggressive ground.
Palm Terminal for Secure Connections. The four-hole palm gives a flat, bolted connection that does not loosen easily with vibration, thermal cycling or soil movement. Several conductors can be terminated on one rod.
Low and Stable Earth Resistance. A solid rod with a reliable bolted joint keeps resistance low and steady. This is essential for protecting people and equipment during earth faults and surges.
Designed to IS 3043. The rods follow IS 3043, the Indian Standard code of practice for earthing. This makes them suitable for projects that must meet electrical inspection and consultant specifications.
Tested Quality. Products are tested under UL and CPRI standards, so every batch performs consistently.
Cost-Effective. GI earth rods offer good performance at a lower cost than copper-bonded alternatives. This makes them a practical choice for large projects that need many earth pits.
Applications of GI Earth Rods with Palm
GI earth rods with palm terminals are used wherever dependable grounding is required, including:
Residential buildings, apartments and housing societies
Commercial complexes, malls, hospitals and offices
Industrial plants, factories and heavy machinery
Electrical panels, DG sets, UPS and inverter systems
Transformers, substations and distribution networks (DISCOMs)
Solar power plants and rooftop solar installations
Telecom towers and data centres
Railway and metro electrification projects
Lightning protection systems and surge protection devices
Petrol pumps, warehouses and infrastructure projects
Palm vs Clamp: Which GI Earth Rod Should You Choose?
SG Power manufactures GI earth rods in two connection types: Palm and Clamp.
| Type | What it is | Best when |
|---|---|---|
| Palm-type rods | A fixed, drilled plate at the top of the rod. | You need a permanent bolted joint, multiple conductor connections, or a neat, inspection-friendly termination inside an earth pit. |
| Clamp-type rods | A separate clamp that grips the conductor. | Conductor sizes vary, or the connection may be changed later. |
For most panel, equipment and lightning-protection earthing where several strips meet at one point, the palm design is the more robust and easier option. Our team can help you choose the right type for your site, and you can see the alternative on the GI earth rods with clamp page.
Installation Guidelines
Select the location. Choose a spot with moist soil where possible, away from foundations and heavy traffic.
Prepare the pit. Excavate or bore the earth pit to the required depth according to IS 3043 and project drawings.
Drive or place the rod. Install the GI rod vertically so the palm stays accessible at the top of the pit.
Use backfill compound. In high-resistivity soil, surround the rod with an earth-enhancing backfill compound to lower and stabilise resistance.
Connect conductors. Bolt the GI strip, cable lugs or conductors to the palm using the pre-drilled holes. Tighten with suitable nuts, bolts and washers.
Install the earth pit cover. Protect the connection with an earth pit cover for safety and easy inspection.
Test the resistance. Measure the earth resistance with an earth tester and record the values for future maintenance.
SG Power also supplies backfill compounds, earth pit covers, GI strips, lightning arresters and surge protection devices, so you can source a complete earthing system from one supplier.
