Product Description

 

Our energy-efficient secondary-class oil-immersed transformer embodies the pinnacle of innovation and advanced engineering. Leveraging cutting-edge materials, breakthrough technologies, and a blend of independent innovation with global technological introductions, we have meticulously optimized and redesigned the core and coil structure. This revolutionary approach significantly reduces no-load losses and noise, marking a new era in high-performance, self-developed transformers.

Oil-immersed transformers bring a multitude of benefits to the table. With superior heat dissipation, they ensure unwavering transformer stability. Their exceptional insulation performance guarantees high reliability, while the ease of voltage adjustment accommodates diverse electrical requirements seamlessly. Furthermore, the mature technology behind these transformers ensures both cost-efficiency and dependability, making them a cornerstone of modern electrical infrastructure.

Iron Core: Crafted from high permeability, magnetic grain-oriented, cold-rolled silicon steel sheets, the iron core represents a new era in transformer cores. Featuring a fully oblique joint and a multi-stepped core section, both the iron yoke and the core maintain equal sections, ensuring optimal magnetic performance and structural integrity.

Winding: Our windings utilize a corrugated oil passage and a non-immersion paint process, secured with a tightening belt for enhanced stability. The concentric coil design features high-voltage windings equipped with taps that correspond to specific voltage requirements, seamlessly connecting to the tap changer. The switch, mounted on the box cover, allows for voltage adjustments post power supply cutoff, ensuring adaptability and precision.

Safety protection device Transformers ranging from 30-2000kVA are equipped with a pressure relief valve. Additionally, a gas relay with alarm and trip terminals can be installed based on user specifications, providing an extra layer of safety and operational reliability.

Oil temperature measuring device: To ensure accurate temperature monitoring, our transformers feature a glass thermometer tub holder positioned at the top of the oil tank, extending into the oil by 120±10 mm. For transformers within the 1000-2000kVA range, an outdoor signal thermometer is included, offering precise temperature readings and enhanced operational oversight.
