A chemical earthing electrode is a sealed metal pipe, filled with a conductive crystalline mix, that is installed in a bore and surrounded by an earth enhancing compound. It gives fault and lightning current a low and stable path into the ground, needs no watering, and lasts longer than conventional pipe or plate earthing. It is also called a chemical earth electrode or a maintenance-free earthing electrode.
Each SG Power electrode has three parts:
GI, copper bonded steel or pure copper, which carries the current and resists corrosion.
A crystalline conductive mix (or an inner pipe or strip) sealed inside the pipe.
A clamp, lug or strip at the top for connecting the earthing conductor.
In the Indian market, "chemical earthing rod" and "chemical earthing electrode" usually mean the same product: a filled, sealed pipe installed with backfill compound. The word "rod" is used loosely by buyers, contractors and tender documents. International specifications often call the same product a chemical grounding electrode or grounding rod.
| Term buyers use | What it normally means | SG Power product |
|---|---|---|
| Chemical earthing rod | Filled, sealed pipe electrode installed with backfill compound | Chemical earthing electrode (this page) |
| Chemical earthing electrode | Same as above | Chemical earthing electrode (this page) |
| Maintenance-free earthing electrode | Same as above | Chemical earthing electrode (this page) |
| Copper bonded earthing rod | Solid steel rod with bonded copper, driven into the ground | Copper bonded earth rods |
| GI earthing rod | Solid galvanised steel rod, driven into the ground | GI earth rods |
If your tender or bill of quantities says "chemical earthing rod", check the construction, material, length and diameter it specifies. If it describes a pipe with conductive filling and backfill compound, it is a chemical earthing electrode. If it describes a solid rod that is driven in, see our earthing rods.
A chemical earth electrode works by increasing the contact area with the soil and keeping that contact moist and conductive all year:
The electrode is placed in a bore, usually 2 m to 3 m deep.
Earth enhancing compound, a carbon- or graphite-based conductive mix, is mixed with water and fills the gap between the electrode and the soil.
The compound sets around the electrode, lowers the resistance of the surrounding zone and holds moisture.
The conductive core inside the electrode carries current along its full length.
Fault or lightning current flows from the earthing conductor, through the electrode and compound, into the soil, keeping touch and step voltages within safe limits across the earthing system.
Because the compound does not wash out like salt and charcoal, the earth resistance stays low through dry seasons. For the full process, see our guide What Is Chemical Earthing?
Chemical earthing electrodes are grouped in two ways: by the material of the outer pipe, and by the construction inside it.
| Material | Construction | Best for |
|---|---|---|
| GI (galvanised iron) | Hot-dip galvanised steel pipe | Budget projects, low-corrosion soil, temporary or short-life sites |
| Copper bonded | Steel pipe with copper molecularly bonded to it | Most industrial, utility and solar projects; long life at moderate cost |
| Pure copper | Solid copper pipe | Highly corrosive soil, coastal sites, critical installations such as data centres |
| Construction | How it is built | Typical use |
|---|---|---|
| Standard | Single pipe filled with conductive mix | General earthing of panels, buildings and equipment |
| Pipe in pipe | Inner pipe inside the outer pipe, with conductive mix between them | Higher fault current: substations, transformers, DG sets |
| Strip in pipe | Metal strip inside the pipe, with conductive mix around it | High fault current and lightning protection, larger contact area |
We make all nine combinations of material and construction. Each is also sold under the names buyers commonly search for.
| Product | Material | Construction | Also called |
|---|---|---|---|
| GI earth electrode, standard | GI | Standard | GI chemical earthing rod |
| GI earth electrode, pipe in pipe | GI | Pipe in pipe | GI pipe in pipe chemical earthing |

Every material is made in six nominal bores (40, 48, 58, 76, 88 and 115 mm), five lengths (1, 1.5, 2, 3 and 6 m) and three pipe wall classes (standard, Class B and Class C). Custom lengths, diameters and terminals are made to order for bulk projects. See the full model list and part numbers below.
Every SG Power chemical earthing electrode has a part number that shows its material, nominal bore and length. Quote the part number together with the pipe wall class in your enquiry or bill of quantities, and we will confirm the construction (standard, pipe in pipe or flat in pipe) on the datasheet.
| Part of the code | Meaning | Example: CBE76SG300 |
|---|---|---|
| Prefix | GIE = GI, CBE = copper bonded, PCE = pure copper | CBE: copper bonded |
| Number | Nominal bore in mm: 40, 48, 58, 76, 88 or 115 | 76: 76 mm nominal bore |
| SG | SG Power | SG |
| Last digits | Length code: 100 = 1,000 mm, 150 = 1,500 mm, 200 = 2,000 mm, 300 = 3,000 mm, 600 = 6,000 mm | 300: 3,000 mm (3 m) |
The part number is the same for every wall class, so always add the class to your order: for example, CBE76SG300, Class B.

Copper bonded is the best choice for most projects, because it gives high conductivity and long life at a moderate cost. Choose GI when the budget is tight and the soil is not corrosive, and pure copper when the soil is highly corrosive or the site is critical.
| Factor | GI | Copper bonded | Pure copper |
|---|---|---|---|
| Conductivity | Moderate | High | Highest |
| Corrosion resistance | Low to moderate | High | Highest |
| Mechanical strength | High | High (steel core) | Lower |
| Service life | Shorter | Long | Longest |
| Initial cost | Lowest | Moderate | Highest |
| Lifecycle cost | Higher (replacement) | Low | Low |
For a detailed comparison, read Copper Bonded vs GI Earth Electrode.
A chemical earth electrode gives lower and more stable earth resistance than conventional pipe or plate earthing, needs no watering and corrodes less. Conventional earthing costs less at first, but its resistance rises in dry weather and the salt and charcoal backfill corrodes the electrode.
| Feature | Chemical earth electrode | Conventional pipe or plate earthing |
|---|---|---|
| Electrode | Sealed GI, copper bonded or copper pipe with conductive core | Open GI pipe or GI or copper plate |
| Backfill | Earth enhancing compound | Salt, charcoal and soil |
| Earth resistance through the year | Low and stable | Rises in dry seasons |
| Watering | Not needed | Regular watering needed |
| Corrosion | Low | High, because of salt |
| Maintenance | Periodic testing only | Watering, refilling and replacement |
| Installation space | Narrow bore | Large pit for plates |
| Initial cost | Higher | Lower |
| Lifecycle cost | Lower | Higher |

Measure soil resistivity at site with a four-pin (Wenner) test; this sets how many electrodes you need.
Know the fault level and duration to size the electrode and conductor.
Set the target earth resistance from the project specification, for example below 1 ohm for substations or below 5 ohms for buildings.
Check corrosion conditions: coastal, chemical or waterlogged soil calls for copper bonded or copper.
Choose material and construction to balance budget and service life.
Work out the number and spacing of electrodes; parallel electrodes are usually spaced at least twice their length apart.
Plan connections and accessories: compound, clamps, earthing strips, earth pit covers and exothermic welding.
Not sure how many electrodes your site needs? Share your soil resistivity and target resistance and our engineers will work it out.
Procurement teams comparing chemical earthing rod manufacturers should check these ten points before placing a bulk order:
| # | Check | What to ask for |
|---|---|---|
| 1 | Standards compliance | IS 3043 design, and the standard named on the datasheet |
| 2 | Test reports | Short-circuit, material and coating test reports; ISO 9001 certificate |
| 3 | Material quality | Galvanising thickness, copper bonding thickness, copper purity |
| 4 | Fault current rating | A rating matched to your system fault level and duration |
| 5 | Filling and sealing | Conductive filling along the full length, sealed at both ends |
| 6 | Manufacturer or trader | In-house production, factory inspection allowed |
| 7 | Product range | All materials and constructions, plus compound and accessories |
| 8 | Project references | Similar projects for utilities, railways or EPC contractors |
| 9 | Delivery capability | Stock of standard sizes, lead time for bulk, dispatch to site |
| 10 | Lifecycle value | Service life and replacement cost, not just the unit price |
Buying from a direct manufacturer rather than a trader gives you better quality control, traceability by batch and access to custom sizes.
The chemical earthing electrode price depends mainly on material, size and construction. Copper costs most, GI least, and pipe in pipe or strip in pipe costs more than standard. Prices also follow copper and steel market rates, so we quote per project.
| Price factor | Effect on price |
|---|---|
| Material | GI lowest, copper bonded moderate, pure copper highest |
| Length and diameter | Longer and wider electrodes cost more |
| Construction | Pipe in pipe and strip in pipe cost more than standard |
| Coating thickness | Thicker copper bonding or galvanising costs more |
| Quantity | Bulk and project orders get better rates |
| Accessories | Compound, cover, clamp and conductor add to the per-pit cost |
| Delivery location | Freight to remote sites adds to the landed cost |
Indicative ex-works prices for bulk orders. Final rates depend on quantity, construction and the copper and steel market on the date of the quotation.
| Size | GI | Copper bonded | Pure copper |
|---|---|---|---|
| 1 m (about 3 ft) | Depends on LME Price | Depends on LME Price | Depends on LME Price |
| 2 m (about 6.5 ft) | Depends on LME Price | Depends on LME Price | Depends on LME Price |
| 3 m (about 10 ft) | Depends on LME Price | Depends on LME Price | Depends on LME Price |
For reference, public B2B listings in Delhi NCR in October 2026 show roughly ₹1,085 to ₹11,999 per electrode for common sizes. Very low prices usually mean a thin coating, a short length or no conductive filling, so compare the specification, not just the price.

Every SG Power chemical earthing electrode goes through eight stages at our own facility:
Raw material inspection: steel or copper pipe and strip checked for size, wall thickness and composition.
Cutting and forming: pipes cut to length and the terminal prepared.
Coating: hot-dip galvanising for GI, or molecular copper bonding for copper bonded electrodes.
Coating check: thickness measured on samples from each batch.
Filling: the pipe is filled with conductive crystalline mix along its full length, with the inner pipe or strip for pipe in pipe and strip in pipe models.
Sealing: both ends sealed so the filling stays dry and intact.
Final testing: dimensional, visual and continuity checks, with records kept by batch.
Marking and packing: batch marking for traceability and packing for safe transport to site.
