Oil Immersed Transformer 110kV
·Product introduction
110kV three-phase oil immersed power transformer is manufactured according to IEC60076 standard of the Electrotechnical Commission and standards GB1094.1 ~ 2-1996 and GB1094.3.5-1985 with frequency of 50Hz, and is suitable for power transmission and transformation of industrial and agricultural power grid. The new series of 110kV power transformers are characterized by low noise, low partial discharge, low temperature rise, short circuit resistance, impact resistance, no leakage and beautiful appearance.
·Service conditions
1. The maximum ambient air temperature shall not exceed 40℃, and the minimum shall not below - 25℃;
2. The altitude shall not exceed 1000m. If special customized transformers and low-voltage components are used, the altitude can reach 4000m;
3. The vertical inclination is no more than 5°, and no violent vibration and impact;
4. The air humidity is not more than 90% (+ 25℃);
5. No gas and conductive dust that will seriously affect the insulation of transformer, no explosion hazard and corrosion of electrical components;
6. Outdoor wind speed shall not exceed 35m /s.
7. If service conditions beyond the above, specially customized product is available.
