Halogen-free medium-voltage TBM reeling cable
The ZH version keeps the power, earth, control and monitoring arrangement of the TBM reeling family while using a black halogen-free PUR outer sheath. Lower- and higher-voltage configurations share a page, but their dimension tables remain voltage-specific.
Where it is used
Reeling power and monitoring connections on tunnel boring equipment when a halogen-free sheath construction is specified.
Cable construction
