ELECTRICAL CABLE WITH A TUBE FOR AN OPTICAL CABLE
摘要:
The invention refers to an electrical cable (C5) with three insulated conductors (51,52,53), a tube (58) for an optical cable, a strip (57) of elastic material embedding the tube and a jacket (56). When the cable (C5) is handled, e.g. suspended between poles or dredged into the ground, the tube (58) can be deformed by external forces. This makes it impossible to blow or float the optical cable into the tube. The tube (58) is protected by the strip (57) and especially by the strip having a flat interval (15) in proximity to the tube. External forces from e.g. suspension equipment will mainly deform the strip (57) at the ends of the interval (15) and less of the forces will hit the tube (58). The deformation sets up an interior pressure in the strip that acts in sideward direction on the tube and contributes to keep it round and non deformed.
