The products are in accordance with Chinese national GB standards and the international IEC standards.

S13 series transformer adopts high quality material for copper winding. 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.

Product features

1. The transformer core is made of high-quality cold-rolled silicon steel sheets with high magnetic conductivity and low loss. With a five-stage joint stacking structure, the layers gap is small, and the joints of each layer are staggered, which greatly reduces the no-load loss and current and noise.

2. The structure of the transformer body is compact, which reduces the radial force during short circuit and has strong ability to resist sudden short circuit.

3.The transformer is  fully sealed and free for maintenance to prolong usage life to more than 30 years.
