At Zhongshao Electric Co., Ltd. Changsha Branch, we take immense pride in offering a wide array of pioneering transformer solutions. Our main products span from 10KV to 69KV S11, S13, S20, and S22 series transformers with cutting-edge three-dimensional magnetic circuit coil iron core technology to the innovative SH15 amorphous alloy series. Our SCB10, SCB11, SCB12, SCB13, and SCB15 series boast exceptional resin insulated dry-type transformers. We also specialize in pre-installed substations (both European and American styles), high and low voltage switchgear, and are adept at designing bespoke and non-standardized transformer solutions tailored to specific client needs. These high-caliber transformers serve the crucial needs of power sectors, enterprises, institutions, factories, and mining enterprises throughout the year. Our transformers have undergone rigorous appraisal by national authorities and are recognized by power regulatory bodies, reflecting our unwavering commitment to quality. We adopt top-tier hardware and software for production, ensuring that all product quality metrics meet and often exceed the advanced standards in China.
