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 the oval cross-section. In addition, a high degree of filling with gaskets and reliable fixation increase the resistance of the product to short-circuit currents.
Low losses: due to the fact that the oil transformer with a spatial twisted core is characterized by the absence of joints, low magnetic resistance, the coincidence of the direction of magnetic flux in the corner parts with the rolling direction of silicon steel, high winding density and light weight of the core, compared with traditional oil transformers with a laminated core, the no-load loss Po is reduced by 18-28%, and the current idle speed Io is reduced by 50–60%. The energy saving effect is significant, operation is economical.
Low noise level: The noise level of the space-twisted core oil transformer is 5-10 dB lower than that of the laminated core oil transformer. This is an ideal low noise product.
