Hz power systems with rated voltages up to 20kV. It is suitable for use in petroleum, metallurgy, chemical, textile, light industry, and other sectors, as well as in dusty environments where reliable power distribution is required.

Performance Characteristics The transformer core is made from high-permeability, grain-oriented, cold-rolled silicon steel sheets. It adopts a new step-lap laminated structure with a multi-step circular cross-section for both the core column and yoke, ensuring low losses and reduced noise.

The windings feature corrugated oil channels for improved cooling and mechanical strength. They are tightly bound and use concentric coil structures.

The high-voltage winding includes taps connected to an off-circuit tap changer mounted on the tank cover, allowing voltage adjustment only when the transformer is de-energized. Transformers rated 30–2000 kVA are equipped with a pressure relief valve. Gas relays with alarm and trip .

A glass-tube thermometer socket is installed on the top of the tank, and units from 1000–2000 kVA include an outdoor signal thermometer for temperature monitoring.

The oil tank uses a corrugated-wall design that functions as both a cooling surface and a flexible expansion chamber, eliminating the need for a conservator and reducing overall height. The surface is electrostatically sprayed and baked for long-lasting corrosion protection.

A vacuum oil-filling process is used during manufacturing to comple n, which minimizes insulation degradation and eliminates the need for routine oil testing. Advantages Compact and maintenance-free design, high efficiency with low losses, reliable operation under harsh or dusty conditions, and long service life.
