If you're going to buy customized 35kv oil immersed power transformer made in China, welcome to get quotation from our factory. Quality products and reasonable price are available.
Oil immersed power transformers are electrical devices that convert high-voltage electricity to low-voltage electricity for safe distribution to homes, buildings, and industries. These transformers are called oil immersed because they use oil as a coolant and insulator.The oil immersed power transformers is used for regulating voltage and AC power transmission. The advantages include small dimension, reasonable price, strong weather resistance and so on. It is applicable to power systems, industrial and mining enterprises, transportation, post and telecommunications sector, research institutes, etc.Smart and diverse structures and nice appearance make this product to meet the needs of different users.

oil immersed transformers Performance characteristics
Low Losses
The core is made of high-quality high-permeability cold-rolled silicon steels sheets. The Swiss automatic core stacking machine is used for vertical and horizontal shearing, and multi-stage full skew joint automatic stacking is employed. The core binding process utilizes integral pressure and PET tape binding techniques, effectively reducing the transformer's no-load losses and no-load current. Performance indicators of the transformer surpass national standards.
Low Noise
The noise of the oil-immersed self-cooling transformers is primarily caused by electromagnetic noise from the core. To reduce noise, our company has taken the following measures:
(1) Low magnetic flux density design.
(2) High-quality high-permeability silicon steel sheets.
(3) Use of the Swiss automatic stacking machine to control stacking precision.
(4) Reliable clamping and bracing measures.
(5) Special damping measures.
Strong Short Circuit Resistance
To ensure that the transformers can withstand the impact of short-circuit currents without causing any thermal or mechanical damage, our company has taken the following measures in design and manufacturing:
(1) Reasonable calculation of turns and balance for transformer coils, using semi-hard copper wire.
(2) Strength and stiffness calculations for all core clamping components, meeting safety requirements for maximum short-circuit mechanical forces.
(3) Densified treatment of winding spacers, using high-density rigid cardboard.
(4) Integral assembly and compression of windings, ensuring assembly accuracy and short-circuit withstand capability.
