Petrochemical industry

In a petrochemical industry facility in the Czech Republic, there arose a need to simplify and clarify the disconnection of incoming cables within the medium-voltage distribution system. The existing solution was not optimal from a maintenance perspective, and interventions in the cabling were time-consuming and operationally complex.

The customer required a solution that would enable fast, safe, and unambiguous separation of cable routes, with an emphasis on operator safety and access control.

Within a project in the petrochemical industry in the Czech Republic, a solution was required for the transition and interconnection of different types of medium-voltage cables. The key requirements were a clear cable arrangement, sufficient space for handling large-diameter cables, and the maintenance of operational safety.

For a pumping station project in Russia, the customer required a medium-voltage bypass switching solution that would allow safe switching between the grid and the converter output. The key requirement was to completely eliminate any possibility of feeding grid voltage into the converter output, even in the event of operator error.

In the initial phase, two technically feasible solutions were discussed in detail:

• a solution using a simple disconnector,
• a solution using a changeover disconnector.

Within a project for a foundry in Poland, it was necessary to design a medium-voltage switchgear capable of handling high currents at a voltage level of 36 kV while simultaneously adapting to the limited installation space of the facility. The solution had to be clear in layout, service-accessible, and operationally safe in a demanding industrial environment.
