SZ10-31500/110 type power transformer is the mainstream product of 110kV class on-load voltage regulating power transformer. It adopts high-quality high-permeability silicon steel sheet and low-loss electromagnetic wire, combined with optimized iron core and winding structure design, and has the characteristics of low loss, high efficiency and low temperature rise.
The on-load tap-changer adopts vacuum arc extinguishing structure, which is reliable in operation and has a long service life. It can realize 35-level voltage regulation to meet the voltage requirements under different load conditions. The overall structure of the product is compact, the floor area is small, and the installation and maintenance are convenient.
It is suitable for 110kV substations, large industrial enterprises’ own power plants, regional distribution networks and other power systems. This product complies with national standards such as GB1094.1-2013, GB1094.2-2013, GB1094.3-2003, GB1094.5-2003, and its performance indicators have reached the domestic advanced level.
