Earth Mats & Grids
Earth mats and grids are the buried mesh of copper or galvanised-steel conductors that keep step and touch voltages within safe limits across a substation, switchyard or equipment yard. LPES supplies prefabricated copper and GI lattice mats, potential-grading mats for operator positions and gates, and the conductors, exothermic joints and risers to build an IEEE 80 grid.
