Product overview
Independent development of products , Type/S13 relies on the basis of the original S11 type distribution transformer, through the research of new material, new process by combining and independent innovation and technological introduction ways, through the optimization of iron core and coil structure innovation design, achieve the goal of no-load loss and lower noise.
No-load loss dropped by an average of 37%. Noise level compared with the current national standard JB/T10088-2004 average fell 20%,product performance level has reached the domestic advanced level.
