Abstract

The fence comprises plastics coated wire netting stretched between posts. Before coating with plastics, a conductive strand of enamelled or varnished copper is woven with the wire of the netting to form conductive loops A-A'. The conductive loop is connected to electronic equipment to detect breakage or modification of the conductive lines and signal an alarm. In an alternative embodiment the conductive lines are formed by metallization on plastics coated wire which is then given a further plastics coating.
