Electrical cable for vertical applications
An electrical cable for vertical applications includes a core having a length L, a sheath surrounding the core and extending through the whole length L and a reinforcing jacket surrounding the sheath and in direct contact therewith. The reinforcing jacket is made of concentric layers including a first layer longitudinally extending from a first cable end (the proximal or upper cable end, in use) towards a second cable end (the distal or lower cable end, in use) substantially along the whole length L. The reinforcing jacket also includes at least one further layer longitudinally extending from the first cable end towards the second cable end for a length shorter than L. At least one layer of the reinforcing jacket is a circumferentially closed metal tube.
