Original product description

Introducing a groundbreaking innovation in transformer technology: the oil-immersed transformer. This state-of-the-art equipment showcases a brilliantly engineered structure and unparalleled performance, setting a new standard in the industry.

Utilizing oil as both its primary insulation and cooling medium, our transformer offers flexible cooling solutions including oil-cooled self-cooling, oil-cooled air-cooling, oil-cooled water-cooling, and forced oil circulation.

The meticulously designed components, such as the iron core, windings, oil tank, oil reservoir, and more, ensure exceptional efficiency and safety.

This cutting-edge transformer also features a respirator, explosion-proof tube, heat sink, insulation bushing, tap changer, gas relay, thermometer, and oil purifier, all working together harmoniously to deliver reliable and sustainable energy transformation.

Due to the long-term immersion of the silicon steel sheets in the transformer, the remarkable elasticity of the transformer oil provides a natural buffer by seeping into the interlayers. This unique characteristic contributes to the oil-immersed transformer's low noise .

However, it is important to consider that the voltage regulating switch is housed within the oil tank. During voltage adjustments, the condition of the switch . In the event of poor , it can simulate circuit disconnection.

A compromised , as excessive loads may cause the switch to burn out, demanding proactive monitoring and maintenance. Transformer normal service conditions 1. Positioned at elevations not exceeding 1000m above sea level;2. Capable of withstanding a peak air temperature of up to +40ºC;3.

Endures a maximum daily average air temperature of +30ºC;4. Withstands a highest annual average air temperature of +20ºC;5. Operates effectively even at a chilling low outdoor air temperature of -2 5ºC.

(defines in detail when transformer in special service conditions ) Type of cooling (1) Oil-immersed transformers predominantly utilize three advanced cooling methods: oil-immersed self-cooling, oil-immersed air-cooling, and forced oil circulation.

The self-cooling technique capitalizes on the natural convection of oil to proficiently dissipate heat, ensuring optimal cooling. (2). The air-cooling method builds upon self-cooling by integrating fan
