ABSTRACT OF THE DISCLOSURE: System and method for the re- strained and flame-retardant laying of one or more electric cables in a duct with a flat bottom. The ductway comprises a series of rigid and non-flammable elongated elements, each with a U-shape cross section, which are individually anchored to a flat floor and are arranged so that there is a space between contiguous elements. This space is sealed along its outer perimeter with a flexible and non-flammable material thereby forming a longitudinally sealed duct. One or more electric cables are laid inside the duct and the cable ends are fastened in fixed positions. The duct is filled with sandy materials and is completed with a slab attached to the top of each elongated element and arranged so that there is a space between contiguous slabs. This latter space is sealed along its outer perimeter with a flexible and non- flammable material. The duct and the sandy materials constitute protection against fire. The spaces between contiguous elongated elements and between corresponding contiguous slabs serve to avoid the harmful effects of forces, generated both inside and outside of the duct,due to variation of cable working temperature and to settling.
