Earthing Materials & Electrodes
Earthing Strips & Wires
Earthing Strips & Wires connect an earthing network using conductors selected for duty, corrosion and the approved layout.
Product-type reference. The supplied make and configuration are confirmed in your quotation.
GI earthing strips, copper strips and earthing wires
Tirupati Power Enterprises supplies earthing strips and wires for industrial, project and maintenance requirements from Kolkata. For a GI earthing strip quotation, send the approved width and thickness, galvanising/finish requirement, total length and delivery format. Identify copper strip and wire requirements separately so material and quantities are clear.
This page covers conductors and their supply specification. Earthing electrodes, enhancement compound, pit covers and completed earthing-system work are separate BOQ lines. Send the approved drawing revision and plant location in West Bengal, Odisha, Assam or elsewhere in India to obtain an offer against the actual project requirement.
Information to include in your RFQ
Selection requirements for this product type |

Copper/GI or other specified material |
Strip width/thickness or wire cross-section |
Length, finish and connection method |
Fault duty, corrosion and installation route |
Replacement and quotation checks
For a replacement, send the existing earthing strips & wires reference and photographs of its markings, connections and mounting. Include the equipment drawing or datasheet where available. Identify which functions must remain unchanged and whether an alternative make is acceptable.

Earthing strip and wire procurement schedule
Use the dimensions and material selected by the electrical designer. A purchasing table is not a universal earthing-conductor sizing rule or proof of a supplied product’s certification.
Buying detail | Include in your RFQ | Confirmation to request |
|---|---|---|
Material | GI/galvanised steel, copper or other specified material/grade | Keep different materials on distinct BOQ lines |
Cross-section | Strip width × thickness or wire size and construction | Confirm tolerances and the approved conductor specification |
Finish | Required coating/finish and inspection evidence | State the project requirement instead of assuming one coating thickness |
Supply lengths | Total metres, straight lengths/coils and handling constraints | Confirm deliverable lengths and how quantity will be measured |
Connections | Clamps, joints, lugs, bolts and dissimilar-material interfaces | Identify compatible joining parts and the installation design |
Documents and destination | Material/coating evidence, drawing revision and delivery details | Have the offered material and document scope confirmed in writing |
Compare quotations for the same supply scope
GI earthing strip prices must be compared on the same material, dimensions, finish and unit. A per-kilogram rate and a per-metre rate are not directly comparable without an agreed conversion and quantity basis. State straight-length or coil requirements, cutting scope, packaging, GST and freight. Keep copper and GI offers separate; equal cross-sectional area does not establish equal corrosion behaviour or suitability.
Prepare your requirement for a quotation
For a project, send the earthing BOQ with material, dimensions and quantities for each line. Include joining accessories and any specified material or coating reports.
For maintenance, share the existing conductor and connection details with the approved replacement requirement. If dimensions or material are changing, obtain the designer’s approval rather than treating the substitution as a pricing decision alone.
- Material/grade, width and thickness or wire size, finish and tolerances.
- Length/weight quantities with a clear purchasing unit.
- Coils/straight lengths, joints/clamps and interface requirements.
- Drawing revision, documents, plant PIN code and delivery deadline.
Checks before you approve the order
Use project-specific requirements
Tata Power’s published procurement specification is an example of dimensions, lengths and finish being defined for a particular job. Its values are not universal TPE product ratings.
Check the quantity unit
Agree metres, kilograms, length tolerances and any conversion basis before comparing supplier rates.
Keep the conductor and system distinct
Earthing-system performance depends on the approved design and installation. A conductor purchase alone does not establish a resistance result.

Questions about Earthing Strips & Wires
What should I check before selecting earthing strips & wires?
Equal cross-sectional area does not establish identical corrosion resistance or mechanical performance. Specify material and joining method explicitly.
What information is needed to quote earthing strips & wires?
Provide copper/GI or other specified material; strip width/thickness or wire cross-section; length, finish and connection method; fault duty, corrosion and installation route. Include the quantity, requested make or existing reference and delivery PIN code.
What details are needed for a GI earthing strip price?
Provide width × thickness, material/grade, galvanising/finish, length or weight quantity, supply format and delivery location. Include document and accessory requirements.
Can I compare a kilogram price with a metre price?
Only using an agreed quantity/conversion basis for the specified material and dimensions. State the purchase and acceptance units in the enquiry.
Can copper strip replace GI strip of the same size?
The design, connections, corrosion environment and material interfaces need review. Do not approve a substitution solely because dimensions match.
Are clamps and joints included with the strip?
Not automatically. List joining accessories, bolts, clamps and any transition components as separate required items.
Do all GI earthing strips have one standard coating thickness?
Specify the coating and evidence required by your project or approved product specification. The proposed material must be confirmed against that requirement.
