Medium-voltage TBM reeling cable
This red-sheathed screened cable supplies tunnel boring machine reels where power, earth, control and monitoring functions need to travel together. The four voltage grades are grouped on one page, with dimensions listed by grade rather than presented as interchangeable.
Where it is used
TBM reeling drums and tunnel construction power feeds; check reel geometry, duty cycle and monitoring interface for each project.
