High automatic stacking of distribution transformer cores – Ground for smart manufacturing

The newly developed GEORG autostack 400 is an offline system for the automatic stacking of distribution transformer cores, developed within the cooperation between GEORG and GÜDEL.

This highly automated system is equipped with an interface to GEORG core cutting lines and an integrated data management for core production. The direct data transfer from the cutting line to the robot unit makes time-consuming manual processes redundant.

By this data coupling, the new systems can be easily integrated into digitally networked environments and thus prepare the ground for industry 4.0 / IoT.

GEORG and GÜDEL are looking forward to continue their cooperation in the field of automatic core stacking by developing autostack systems for medium and large power transformers.
