The S13 type is an independently developed product based on the original S11 distribution transformer, incorporating new materials, processes, and a combination of self-innovation and technology introduction. By optimizing and innovating the core and coil structure, it aims to reduce no-load losses and noise. No-load losses have been reduced by an average of 37%, and noise levels have decreased by an average of 20% compared to the current national standard JB/T10088-2004, with the product's performance reaching an advanced level in China.
Advantages
The transformer core is made from imported high-quality cold-rolled silicon steel sheets, which significantly reduce no-load losses and no-load current. Additionally, the core is strapped to ensure its tightness and to reduce noise.
The high and low-voltage windings are made of oxygen-free copper. For low-voltage windings up to 500 kVA, a double-layer cylindrical structure is used. While for 630 kVA and above, a double-helix or quadruple-helix structure is employed. The high-voltage windings use a multi-layer cylindrical structure.
The transformer uses a Dyn11 connection group to reduce harmonic effects on the power grid and improve power quality. It features a fully-sealed structure, which extends its service life and eliminates the transformer suspension core and maintenance.
