Abstract
A tubular sheath made from plastic material used for the mechanical and/or thermal protection of electric cabling is wrapped in a strip of sound-insulating material, the lateral parts of which have been inserted inside the sheath through the slit. The width of the strip, preferably produced from felt, is substantially equal to the sum of the external and internal perimeters of the plastic sheath.
Claims3
A cover for the mechanical and/or thermal protection of electric cabling, comprising:
- a tubular sheath of flexible plastic;
- a strip of sound-insulating felt glued to the sheath and folded longitudinally over the sheath in order to wrap the sheath;
- and
- wherein the sheath is split longitudinally along a slit, and lateral parts of the sound-insulating felt are folded and inserted longitudinally inside the sheath through the slit to provide sound insulation against both an external surface and internal surface of the sheath.
