Abstract (en)
[origin: WO0063500A1] An apparatus for laying underground electric cables, in particular for high-voltage lines, comprises a vehicle (2) towable along a trench (3) and carrying, on a first van (4), a first deposition unit (12) adapted to form a base layer (13) of inert material for heat dissipation at the trench bottom. Mounted on the first van (4) is a guide structure (20) engaging the cable (21) for laying it on the base layer (13) previously compacted by a vibrating plate (18). A second van (5) carries a second deposition unit (30) forming a covering layer (31) of inert material upon the previously laid-down base layer (13) and cable (21).
