● The high-voltage coil adopts a continuous or inner continuous type to improve the longitudinal capacitance distribution of the coil under impulse voltage. The coil adopts an oil-guided circulation structure to reduce the temperature rise of the winding. The design life of the product is 30 years. The coil has internal hardness support, double dovetail垫块 support, and the upper and lower edge insulation is the pressure plate of the entire platform, with high mechanical strength and strong resistance to sudden short circuits. The insulation components inside the coil and between coils become thicker along with the circle, reducing partial discharge. Ensure the overall assembly of the main body, constant pressure drying, uniform coil shrinkage, and small cross-section, effectively improving the electrical strength and short-circuit resistance of the transformer.
● Meet the power supply needs of residents in China's urban power grid.
● Implement national standards such as GB6451.
Main Features and Technical Parameters:
● Low loss: The no-load loss is about 40% lower than the current national standard gb 6451-1999, and the load loss is 15% lower than the current national standard gb6451-1999.
● Low noise: The noise level is less than 60dB, 20dB lower than the standard. If users have special requirements, they can be specially designed and manufactured to meet the power supply needs of residents in China's urban power grid.
● Low partial discharge: The S22 oil-immersed transformer operates without cleaning throughout the process, and the metal parts and insulation parts inside the body are all rounded, with partial discharge controlled below 100pc.
● Strong short-circuit resistance: The S22 oil-immersed transformer designed and manufactured by our company has passed the short-circuit withstand capability test of the Quality Supervision and Inspection Center.
● Beautiful appearance: The wave structure of the oil tank folding plate, spraying, powder electrostatic spraying, wide sheet radiators, never fading.
● No leakage: All sealed stop positions, the upper and lower tanks adopt double-channel sealing, and all stickers are imported. Solemnly promise to avoid leakage.
