Description

10mm Copper Bonded Conductor Manufacturer and Supplier In India – EarthingMart.

10mm Copper Bonded Conductor is a mission-critical earthing component engineered for Indian soil conditions, high fault currents, and long-term corrosion resistance. Offered by EarthingMart, this conductor is purpose-built for EPC contractors, MEP consultants, solar developers, infrastructure projects, and Grade-A electrical contractors seeking predictable performance, standards compliance, and lifecycle reliability.

Designed to meet IS 3043 and IEC 62561 requirements, the 10mm copper bonded conductor delivers low earth resistance across 10–200 Ω-m soil resistivity—performing consistently in monsoon, coastal, rocky, and high-resistivity terrains common across India.

Product Overview & Working Principle

What is a 10mm Copper Bonded Conductor?

A 10mm copper bonded conductor consists of a high-tensile low-carbon steel core metallurgically bonded with 99.9% pure electrolytic copper. Unlike copper-clad or coated wires, the molecular bond ensures no peeling, cracking, or galvanic separation, even under thermal cycling and fault conditions.

How It Works in Earthing Systems?

• The steel core provides mechanical strength and deep-driving capability.

• The thick copper layer ensures excellent conductivity and corrosion resistance.

• When installed in earth grids, vertical electrodes, or ring mains, it dissipates fault and lightning currents safely into soil, stabilizing touch and step potentials.

Performance & Engineering Advantages

Proven Performance in Indian Conditions of 10mm Copper Bonded Conductor

Low Earth Resistance: Optimized conductor geometry delivers reliable resistance values in 10–200 Ω-m soils.

• Corrosion Resistance: Copper layer resists chlorides (coastal belts) and acidic soils during monsoons.

• High Fault Current Capacity: Safely carries short-circuit and lightning surge currents without deformation.

• Mechanical Robustness: Steel core prevents stretching or breakage during trenching and backfilling.

Applications & Use Cases

1. Solar Power Plants (Utility & Rooftop)

Case Example – 50 MW Solar Plant, Rajasthan:
10mm copper bonded conductors were used in array earthing and inverter rooms to achieve <1 Ω earth resistance in sandy, high-resistivity soil with backfill compounds.

2. Electrical Substations & Switchyards

Ensures equipotential bonding for transformers, panels, and gantries, minimizing step and touch voltage risks.

3. Industrial & Manufacturing Facilities

Handles high fault levels from motors, VFDs, and heavy machinery in continuous-duty environments.

4. Commercial & Residential Buildings

Used in ring earthing and foundation earthing for reliable long-term safety.

Installation & Maintenance Guidance (Best Practices)

Installation Guidelines

1. Lay conductor in trenches (minimum 600 mm depth) or as per design.

2. Use exothermic welding or approved clamps for joints—avoid loose mechanical connections.

3. Ensure proper backfill (bentonite/earthing compound) in rocky or dry soils.

4. Maintain continuous loops for ring earthing systems.

Maintenance Recommendations

• Periodic earth resistance testing (annual or pre-monsoon).

• Visual inspection of accessible joints.

• No routine replacement required due to copper-bonded construction.
