A cable winch (100) for deploying and retracting a cable (50) during the installation of powerline cables on transmission towers. The cable winch (100) includes a base frame (102), a spool (110), a drive system (120), a sensor system (200), and a control system (300). The spool (110) is mounted for rotation on the base frame (102) and the cable (50) is releasably securable to the spool (110). The drive system (120) is able to drive rotation of the spool (110) to either pay out or wind in the cable (50) along a cable path. The cable path passes through the sensor system (200), which has a first sensor (244) able to detect and output tension data in relation to the tension in the cable (50) passing through the sensor system (200). The control system (300) is adapted to receive the tension data output by the sensor system (200) and modulate the speed and torque of the drive system (120) in order to maintain a predetermined tension in the cable (50).
