S20 200kVA Oil Immersed Distribution Transformers

The S20 series ‌‌ are high-performance units engineered for stable power distribution demands. Featuring a core made of high-grade silicon steel and a fully sealed tank structure, they ensure low temperature rise and minimal losses across diverse grid environments. The ‌‌ design delivers superior heat dissipation and insulation performance, making it suitable for outdoor installations. Rigorously tested to ISO, SGS, and CE standards, these transformers excel in short-circuit withstand, overload protection, and environmental compliance, meeting global customers' stringent requirements for reliability and safety.

‌‌: As an ‌oil immersed distribution transformer‌, the S20 minimizes energy loss through optimized electromagnetic design, enhancing grid transmission efficiency.

‌‌: The oil cooling system (‌oil filled distribution transformers‌) effectively suppresses temperature rise, ensuring continuous operation at full capacity for extended periods.

‌‌: The sealed construction of the ‌oil immersed transformer‌ is resistant to moisture, dust, and contaminants, enabling reliable performance in harsh conditions like high temperatures and humidity.

‌‌: Integrated pressure relief valves and Buchholz relay protection provide multiple safety layers compliant with international standards.

‌‌: Designed for ease of upkeep with features like oil level gauges and removable components simplifying routine inspections.

strictly follows the comprehensive acceptance testing process to ensure that the performance of each device meets the standards.
