the unlawful removal or misappropriation of copper materials or components, typically from outdoor installations such as power lines, transformers, railway systems, telecommunications networks, and construction sites
see also metal theft
note: Copper is a preferred target due to its high market value, wide use in outdoor and infrastructure applications, and ease of access in many installations at low risk to be caught. Copper theft can lead to substantial economic losses, operational disruptions (e.g., power outages, transport delays), and safety hazards. It is a factor driving material substitution in certain applications.
