Distribution Transformer is basically an electrical isolation transformer which is used to control high voltage power levels and convert low voltage used for homes and businesses. A Distribution transformer is uncomplicated it helps to step down the voltage and provide isolation between primary and secondary. Home and business electricity pass through distribution transformers to reduce high voltage distribution to the end-user level.
Types of Distribution Transformers
There are many transformers used for various purposes. For residential and commercial used transformer manufacturers in Hyderabad provides the best quality. There is a transformer manufacturing company called Vajra Transpower PVT LTD which provides high built quality, and other electrical transformer manufacturers in Hyderabad provide quality but comparatively low.
There are three distribution transformers
- Oil Cooled Transformers
- OLTC Transformers
- Dry Type Transformers
Most of the electrical transformers manufacturers in hyderabad provides these transformers. When it comes to power transformers manufacturer in hyderabad Vajra provides the best quality.
Let’s know the difference between these three transformers
Oil Cooled Transformers: Oil cooled transformers are two types Oil and air cooling, Oil and water cooling. Oil and Air Natural transformer are immersed in oil and the heat generated windings passed on to oil by conduction. The surface of windings heated up and moves towards up it is replaced with cooled oil from the bottom. This method will be used in 30MVA.
Oil Cooling Transformers also called “Oil Impression Transformers”.
Oil Immersed Transformers are
- Oil Natural and Air Natural
- Oil Natural and Air Forced
- Oil Forced and Air Natural
- Oil Forced and Air Forced
Oil and Water Cooling water pass through copper tubes which enhance the cooling of the transformer. This method is used for several MVA transformers. Power transformers manufacturer in hyderabad provides these various transformers.
OLTC (On Load Tap Changer) Transformers: This is not disconnected from the mains supply when the tap setting is changed such type of transformers called OLTC Transformers.
The tapping provides at HV(High Voltage) winding transformers because the high voltage winding is injured on the low-voltage winding.
The Manufacturers provides different On Load Tap changing transformers
The Manufacturers provides different On Load Tap changing transformers
Dry Type Transformers: In Dry Type Transformers, the insulating liquid is not used where it’s winding with a core. There are two types of Dry Type Transformers
- Cast Resin Dry Type Transformer(CRT)
- Vacuum pressure Impregnated Transformer(VPI)
Cast Resin Dry Type Transformer: The primary and secondary windings have summarized with epoxy resin and mostly it is used in high moisture prohibited areas This sum up helps to prevent moisture go through winding material. This type of transformer is available in 25KVA to 12500 KVA.
Vacuum Pressure Impregnated Transformer: This type of transformer is made up of combustible material as insulation of windings. The winding is made in foil in a continuous layer. The primary and secondary winding with the core is laced safely within the vacuum protective box. This type of transformer is available in 5KVA to 30MVA.
