General Description

Transformers TMPG-SESH guarantee for supply of 24-pulse variable frequency induction brushless drive with low-harmonics current is generated in the network. Switching branches without excitation windings of a PBV. Cooling system type "M". Transformer TMPG-SESH serves to compensate for higher harmonics of the current generated by the thyristor converter.

Application of multistage tightness control.
Modern lines of cross-cutting are equipped with spacers of core plates, which allow to reduce losses in the transformer.
Higher harmonics of current circulate in the circuits inside the transformer, they do not enter the network.
Reduced no-load losses, the technology of blending STEP-LAP.
