SGB-RL Dry transformer with open windings and space triangular core
SGB-RL Dry transformer with open windings and space triangular core

SGB-RL Dry transformer with open windings and space triangular core

High mechanical strength: the spatial twisted core has a round cross-section of the rods, which provides better resistance to short-circuit currents compared to an oval cross-section. After vacuum impregnation, the windings have high strength, and a special fastening method allows the product to withstand shock electrodynamic loads in the event of a sudden short circuit without damage.
