Modularity.
Theextensiblecubicleshavesidefemalebushingtoconnect themain busbars through this connectingset. This allows current to flow, while controllingtheelectric fieldbymeansof insulatingelastomerlayers,freeofpartialdischarges.
Thanks to the design of the connecting set, aninternalequipotentialareaiscreated.Hereanumberofcontactsaredistributedinacircleforconnectiontothefemalebushings.
A reliable, strong electrical continuity is thereforeachieved, even when exposed to a short-circuitcurrent. The connecting set also maintains alloperationalfeaturesofthecubicles.
Whiletheinstallationisnotbeingextended,theextensiblecubicles have removable sealing elements for the femalebushings.
The cubicle connecting procedure stands out for its ease and speed of on-siteinstallation,includinginTransformerSubstationswithunevenfloors.
The modularity and extensibility of the system ensure maximum flexibility toconfigureanykindofmediumvoltageelectricaldiagram.
