The Oil Immersed Power Transformer is engineered for high-voltage transmission and distribution networks requiring exceptional reliability, efficiency, and long service life. Filled with high-grade mineral oil for both insulation and cooling, it delivers stable performance under continuous heavy load and harsh environmental conditions.
Key highlights include a core manufactured from cold-rolled grain-oriented silicon steel, a precision-wound copper winding, an on-load tap changer (OLTC) for voltage regulation, and a conservator with silica gel breather for moisture control. Comprehensive protection is provided via Buchholz relay, sudden pressure relay, oil and winding temperature indicators, and an integrated control cabinet.
Each unit undergoes full type and routine tests in accordance with IEC 60076, including lightning impulse, partial discharge, temperature rise, and short-circuit withstand tests. Suitable for utility substations, industrial plants, power generation stations, and infrastructure projects worldwide.
