Specification

Iron Core: The core, constructed from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, represents a new generation of iron cores. The full oblique jointed iron core features a multi-stepped section design, ensuring uniformity across the iron yoke and the core itself, enhancing efficiency and performance.

Winding: Our windings utilize corrugated oil passages and a no immersion paint process, secured with a tightening belt for stability. The concentric coil design includes high-voltage windings with taps for precise voltage adjustments, accessible via a tap changer mounted on the box cover. This allows for seamless changes to the tap voltage post power supply interruption.

Safety Protection Device: Our transformers, ranging from 10-5000kVA, are equipped with safety features like a pressure relief valve. Additionally, a gas relay with alarm and trip terminals can be installed as per user requirements, enhancing safety and operational integrity.

Apply	Mines, oil fields, subways, power plants, schools, hospitals, commercial centers, high-rise buildings
Installation height	The altitude does exceed 1000m
The waveform of the power supply voltage	similar to a sine wave

Oil Temperature Measuring Device: Each transformer comes fitted with a glass thermometer in a tube holder, strategically positioned atop the oil tank, extending 120±10 mm into the oil. For transformers in the 10-5000kVA range, an outdoor signal thermometer is included, providing accurate and reliable temperature monitoring.
