high-performance oil-immersed power transformers
We manufacture high-performance oil-immersed power transformers engineered for reliable voltage regulation, high thermal efficiency, and long service life—ideal for transmission networks and heavy industrial applications up to 200 MVA.
A Step-Up Transformer is an electrical device that increases voltage from a lower level on the primary side to a higher level on the secondary side. It is mainly used in power plants to elevate generator voltage to transmission levels for long-distance power transfer.
A Step-Down Transformer is an electrical device that reduces high voltage from the primary side to a lower voltage on the secondary side. It is mainly used in power distribution systems to supply safe, usable voltage levels to residential, commercial, and industrial loads.
An Auto Transformer is a type of transformer that uses a single winding for both the primary and secondary sides. Unlike a two-winding transformer, it shares part of the same coil for voltage transformation, making it more compact, efficient, and economical.
An OLTC Transformer (On-Load Tap Changer Transformer) is a voltage-regulating power transformer that allows adjustment of its output voltage while under load—without interrupting the power supply. This is essential in systems where voltage stability is critical.
A Generator Transformer connects the electrical output of a generator to the high-voltage transmission network. It steps up the medium voltage generated (e.g. 11–25 kV) to higher voltages (e.g. 132–765 kV) suitable for transmission over long distances.
A Furnace Transformer is a specially designed power transformer used to supply electrical energy to industrial furnaces, like electric arc furnaces (EAF), induction furnaces, and other high-current heating equipment.
