Product Description

Our energy-saving, second-class oil-immersed transformer is an epitome of advanced engineering and innovation. Crafted through extensive research and the application of cutting-edge materials and technology, this transformer boasts an optimized core and coil structure. This innovative design significantly reduces no-load losses and minimizes noise, making it a hallmark of our commitment to excellence.

Oil-immersed transformers are synonymous with reliability and efficiency. They offer superb heat dissipation, ensuring stable and continuous operation. With excellent insulation properties, these transformers promise high reliability. The ease of voltage adjustment makes them ideal for varying electrical demands. Their mature technology and cost-effectiveness further enhance their appeal.

Iron Core: The core features high permeability magnetic grain-oriented cold-rolled silicon steel sheets. This innovative type of iron core has a fully oblique joint, multi-stepped cross-section, and equal sectional areas for both the iron yoke and the core, ensuring optimal performance.

Winding: The winding utilizes a corrugated oil passage with a non-immersion paint process and is secured with a tightening belt. The concentric coil design includes high-voltage windings with taps that meet specific tapping voltage requirements and are connected to a tap changer. The switch, mounted on the box cover, allows for voltage adjustment after power is cut off.

Safety Protection Device: Our transformers, ranging from 30-2000kVA, come with a pressure relief valve. Additionally, a gas relay with an alarm and trip terminal can be installed based on user specifications, ensuring maximum safety and operational integrity.

Oil Temperature Measuring Device: Equipped with a glass thermometer tube holder, the transformer features a tube seat arranged at the top of the oil tank, protruding 120±10 mm into the oil. For transformers between 1000-2000kVA, an outdoor signal thermometer is provided for precise temperature monitoring.
