Lattice type protective grid for forming anti-intrusion fence, has cylindrical elements arranged along corresponding directions, where each element is in form of tube whose inner side receives wire or cable connected to detection unit

摘要

The grid (1) has coplanar cylindrical horizontal and vertical elements (2, 3) arranged along corresponding perpendicular horizontal and vertical directions. The cylindrical elements are in the form tubes (6), where an inner side of each tube receives a wire or an electric cable e.g. coaxial electrical cable, for transmitting electric or light signal or information. The cable is connected to a signal or information detection unit. The cylindrical vertical elements are woven with one another to form a lattice. An independent claim is also included for a method for fabricating a grid.
