An oil-immersed transformer is a type of electrical transformer where the core and windings are submerged in an insulating oil. This oil serves two primary functions: it acts as a highly effective insulator between conductive parts and as a coolant to dissipate heat generated during operation. These transformers are robust, reliable, and highly efficient, making them the standard choice for high-voltage power distribution and transmission networks, typically installed outdoors in substations.

• Effective Cooling: The insulating oil efficiently absorbs heat from the core and windings and transfers it to the radiator fins, allowing for natural or forced circulation and higher overload capacity.
• Superior Insulation: The oil provides much better dielectric strength than air, allowing for a more compact design for a given voltage rating and protecting against short circuits.
• Robust Construction: Designed for long-term, reliable operation (often 25-30 years) in harsh outdoor environments.
• Overload Capacity: Can handle temporary power overloads better than dry-type transformers due to the thermal mass and cooling properties of the oil.
• Protection System: Equipped with a conservator tank (to allow for oil expansion), breather (to absorb moisture from air), and protective relays (Buchholz relay) for internal fault detection.
• Cost-Effective: Generally more economical for high-power applications compared to dry-type transformers.

Here’s a straightforward description of these oil-immersed transformers:

These transformers handle power conversion reliably. They step down high voltage electricity from 11kV or 33kV transmission lines to safer, usable levels like 400V or 240V. This makes them essential for bringing power from the grid into factories, buildings, and towns.

We offer several standard sizes. The 50KVA, 100KVA, and 200KVA units are common for smaller commercial sites or feeding groups of houses. They provide dependable power distribution locally. Moving up, the 500KVA and 1000KVA models suit larger industrial plants or substantial commercial complexes needing more power. The 2000KVA transformer is for very heavy industrial use or supplying power to small districts.

All these transformers use oil for cooling and insulation. This oil circulates naturally or with pumps, keeping the core and windings at safe temperatures during operation. The oil also provides vital electrical insulation inside the tank. The tank itself is robust steel, protecting the internal parts. It’s filled with specially treated transformer oil. This oil is non-flammable and highly stable.

The core is built from thin layers of special electrical steel. This design minimizes energy losses. Copper or aluminum windings are wound precisely around the core. Quality materials and careful construction ensure efficiency and long service life. These transformers meet strict international standards like IEC and IEEE. They are built for safety and reliability.

Standard features include pressure relief devices and oil level indicators. Temperature gauges monitor operating conditions. Many models have tap changers. These allow minor voltage adjustments to compensate for supply variations. Terminations are usually bushing type for secure cable connections. Options include different protection relays, specialized cooling systems, or custom paint finishes. Mounting brackets can also be specified. These transformers are a proven solution for stepping down high voltage power efficiently.

Applications of 50KVA, 100KVA, 200KVA, 500KVA, 1000KVA, 2000KVA, 11kv, 33kv Step-down, 400v, 240v Oil-immersed Transformer

These oil-immersed transformers step high voltage power down to usable levels. They handle 11kV or 33kV input. They deliver safe 400V or 240V output. This makes them vital for many power needs.

The 50KVA units are compact workhorses. They power small factories, shops, and offices. They manage essential machinery, lighting, and outlets reliably. They are a common sight where moderate power is needed.

The 100KVA models offer more muscle. They support larger retail spaces, medical clinics, and light industrial sites. They reliably run heavier equipment, HVAC systems, and multiple circuits. They bridge the gap between small and large demands.

The 200KVA transformers handle serious loads. They serve medium factories, large commercial buildings, and small manufacturing plants. They power production lines, large pumps, and significant lighting arrays. They are built for continuous operation.

The 500KVA size tackles heavy industrial applications. They run large factories, processing plants, and sizable facilities. They supply power to extensive machinery, large motors, and complex processes. They form the backbone of industrial power distribution.

The 1000KVA and 2000KVA units are powerhouses. They feed entire industrial complexes, large manufacturing sites, and major infrastructure projects. They manage huge motors, massive equipment banks, and critical facility systems. They are essential for very high power consumption. Utilities also use them within substations for local distribution.

All these transformers use oil for cooling and insulation. This ensures stable, safe operation under load. They are robust, durable, and designed for long service life. They are the reliable link between the grid and your equipment. Choosing the right size depends entirely on your specific power requirements.

5 FAQs of 50KVA, 100KVA, 200KVA, 500KVA, 1000KVA, 2000KVA, 11kv, 33kv Step-down, 400v, 240v Oil-immersed Transformer

5 Common Questions About Oil-Immersed Transformers (50-2000KVA, 11kV/33kV to 400V/240V)

What does this transformer do?
It lowers voltage. It takes high voltage power from the grid (11kV or 33kV). It steps this down to safer, usable levels (400V or 240V). This makes the power suitable for factories, buildings, or other sites.

What voltages does it handle?
These transformers connect to high-voltage lines. These lines are either 11,000 volts (11kV) or 33,000 volts (33kV). They output much lower voltage. This output is either 400 volts (400V) or 240 volts (240V). The exact input/output depends on your specific needs.

How does it stay cool?
It uses oil. The transformer core and windings sit inside a tank filled with special insulating oil. This oil absorbs heat generated during operation. The heat transfers from the oil to the tank walls. Often, radiators or fins attached to the tank help dissipate this heat into the air.

Where are these sizes used?
Different sizes fit different jobs. A 50KVA or 100KVA unit might power a small factory or large building. A 200KVA or 500KVA transformer often serves medium factories or commercial complexes. Larger units, like 1000KVA or 2000KVA, are common in heavy industry or as substations supplying whole areas.

Is it safe? What protects it?
Built-in safety features exist. The oil tank is very strong. A pressure relief device releases excess pressure quickly if internal faults occur. An oil level gauge shows if oil is low. Temperature gauges monitor operating heat. These features help prevent major failures.
