Earth Mat (Lattice Copper) - Furse

The Earth Mat (Lattice Copper) by Furse is a pre-fabricated earthing grid system constructed from hard-drawn or annealed copper conductors arranged in a lattice mesh pattern, designed for installation below ground level to create a low-impedance earthing network across a defined area. Used as a foundation earthing system for substations, switchyards, telecommunications installations, data centers, and industrial facilities, the lattice copper earth mat distributes fault current and lightning discharge energy across a broad ground contact area, reducing touch voltage, step voltage, and ground potential rise to safe levels during fault events.

The mat is manufactured from bare copper conductor in cross-sectional sizes typically ranging from 25mm² to 120mm², selected based on the maximum fault current the system must carry and the required fault duration without conductor damage. Individual conductors are joined at every intersection point through exothermic welding — commonly using Furse’s own welding system — forming permanent molecular-bonded connections with conductivity equivalent to the parent conductor rather than mechanical joints that can loosen or corrode over time.

Lattice spacing between conductors — typically 0.6 meters to 3 meters center-to-center — is determined by the required surface potential gradient uniformity across the protected area, with tighter spacing reducing touch and step voltage differentials. Copper’s corrosion resistance in most soil types provides a design life exceeding 40 years without significant conductor degradation, supporting the long service life expectations of substation and critical infrastructure earthing systems.

Furse earth mats are engineered in compliance with BS EN 50522, IEEE Std 80, and IEC 60364 earthing system standards, providing documented performance verification for regulatory and safety certification requirements.

In Pakistan, lattice copper earth mats are installed at power utility substations, grid station switchyards, telecommunications tower bases, data centers, and industrial facilities requiring certified low-impedance earthing infrastructure.
