Product Introduction

S-series: refers to transformers with a "three-dimensional wound core" or "stepped laminated core" structure, but "S" in older models often directly represented "three-phase". In the context of S11, it usually refers to a core using high-quality grain-oriented silicon steel sheets and stepped laminated technology.

Stacked core: This refers to the transformer's magnetic circuit core being constructed from stacked, stamped silicon steel sheets. This technology is mature, structurally robust, and highly efficient in production.

Excitation magnetic tape voltage regulation: This is a key feature of this product. It refers to the ability to make minute adjustments to the output voltage by changing the number of turns in the transformer's high-voltage winding (usually via a tap changer) to adapt to fluctuations in the grid voltage.

Application Scope

• This transformer is widely used in power transmission and distribution systems requiring 50Hz frequency and rated voltage of 10kV and below, and is particularly suitable for

• Urban and rural power grid renovation and construction: As a core piece of equipment in the distribution network, providing power to communities and towns.

• Industrial and mining enterprises: Providing power to production equipment in factories and mines.

• Commercial buildings and infrastructure: Providing power to shopping malls, hospitals, schools, airports, and train stations.

• Agricultural irrigation and rural electricity use: Suitable for applications with relatively stable load changes and low requirements for real-time voltage regulation.

• Step-up substations for photovoltaic, wind power, and other new energy power plants (as part of a box-type transformer).
