Engineering applications of copper in strip form include heat-sinks, heat exchangers, condensers, lightning conductors, switchgear, wiring looms, connectors, submersible pumps, roofs, flashings and outside structures. Strip products are also often favoured in the arts and crafts sector, including model making. The purpose of the copper earthing strip is to provide a low resistance path to the ground, which helps to protect people and equipment from electric shocks and damage due to lightning strikes or other electrical faults.
