U10 Insulated Crane Busbar System

U10 Insulated Busbar System The insulated conductor system U10 is a busbar system used for supplying main power and signal current, as well as data transmission (Powercom), especially for overhead crane systems and monorails. Sliprings and multipole slipring units also present no problems.

Capacity: 10 - 100 A.

Insulated Busbars Manufactured Finger Safe

The U10 busbar electrical collectors are finger safe to industry standards VDE 0470-1, protection code IP 21. This saftey regulation is only valid if the copper is housed completely inside the conductor. In hand areas, in which the collectors leave the conductor due to operating conditions, there must be protection against contact installed on site (i.e. barriers or cut-off). This is only necessary for voltages over 25 Volts AC or 60 Volts DC.

The shroud which envelopes the various conductors is an excellent insulator. Therefore our unipole insulated busbars guarantee utmost safety in operation.

Any number of conductors can be installed side by side at minimum space requirement.

Standard rail sections are 6 m long, shorter sections are available.

Usage: Only for indoor systems
