Method and equipment for installing a power cable in a deployment site

Equipment for installation of a single power cable span in a deployment site comprising:

• at least one rail to be fixedly installed in the deployment site;
• a plurality of trolleys slidably couplable to the at least one rail;
• a plurality of holders for releasably connecting the single power cable span to one of the trolleys, each holder comprising a first part and a second part, the first part and the second part being configured to lock a portion of the single power cable span;
• and
• a conveyor belt having a plurality of locations arranged at a predetermined distance one from the other along a longitudinal movement direction of the conveyor belt and movable integrally with the latter, the first part being configured to be removed when the portion of the single power cable span leaves the conveyor belt, wherein each of the locations is suitable for positioning the first part of one of the holders, the conveyor belt being located at a first site and comprising a belt for supporting the single power cable span at the first site, the deployment site being located at a second site different from the first site, the cable span being prepared for installation at the first site and installed at the second site.

A method for installing a single power cable span, the method comprising:

• providing a conveyor belt outside of a deployment site, the deployment site comprising a rail for supporting the single power cable span and a plurality of trolleys, the conveyor belt having a plurality of locations set at a predetermined distance one from the other along a longitudinal movement direction of the conveyor belt, the conveyor belt being located at a first site and comprising a belt for supporting the single power cable span at the first site, the deployment site being located at a second site different from the first site and separated by a section of the cable span, the cable span being prepared for installation at the first site and installed at the second site, the conveyor belt moving integrally with the plurality of locations;
• and
• performing a plurality of repetitive steps until the single power cable span reaches a predetermined position, each repetition of the plurality of repetitive steps comprising:
• moving the conveyor belt,
• while the conveyor belt is moving, positioning a first part of a holder at one of the locations,
• advancing the single power cable span,
• while advancing the single power cable span, laying a portion of the single power cable span on the first part of the holder positioned at the location moving with the conveyor belt,
• connecting a second part of the holder to the first part of the holder to lock the portion of the single power cable span laid on the first part of the holder in between, and
• while the cable span portion locked by the holder is leaving the conveyor belt, removing the first part of the holder from the location moving with the conveyor belt.
