The S20 Series 10kV-35kV Non-excitation Voltage Regulating Transformer is a high-efficiency oil immersed transformer designed for medium-voltage power transmission and distribution. As a leader in energy-saving transformers, it integrates non-excitation voltage regulating technology to adjust voltage safely without interrupting power—making it a backbone of efficient urban and rural power grids. It prioritizes low loss, quiet operation, and long-term reliability, addressing the demand for sustainable infrastructure.
Non-excitation voltage regulation allows voltage adjustments when the transformer is de-energized, ensuring precise control without compromising safety. For grids and industrial systems requiring stable voltage to protect sensitive equipment, this technology prevents fluctuations that could damage machinery or disrupt operations.
The S20 Series is engineered for exceptional efficiency, with loss levels far below industry benchmarks. Its ultra-low no-load and load losses deliver substantial energy savings, making it an eco-friendly choice for utilities and industrial users. This low loss transformer reduces operational costs and carbon emissions, aligning with global sustainability goals.
Noise pollution is minimized through a shock absorption structure and low-noise cooling system. Its quiet performance meets strict night noise standards, making it suitable for residential areas, hospitals, and office parks.
A fully sealed oil tank and high-quality seals prevent leakage and moisture ingress, eliminating frequent maintenance. Seals match the transformer’s service life, reducing workload and avoiding oil spill hazards.
Adopting high-permeability silicon steel sheets and a stepped core structure, the S20 series offers superior mechanical strength and short-circuit withstand capability. This robustness ensures durability under extreme temperatures and sudden load changes.
