11kv 415v 2000 kva Step Down Oil immersed type transformer

Qianlai Electric, as a leading manufacturer of transformers, switchgear, and ring main units in China, always adheres to the production philosophy of “quality first”.
Each process of the transformers produced by Qianlai Electric is strictly in accordance with the specifications, and strict routine factory tests are carried out before leaving the factory,
such as voltage ratio measurement and voltage vector relationship calibration, winding resistance measurement, no-load current and no-load loss measurement, short-circuit impedance and load loss measurement, etc.Stable quality and reasonable prices have enabled our transformers to have good sales both at home and abroad.

What are the core components of a 11kv 415v 2000 kva Step Down Oil immersed type transformer?

Iron core: The magnetic circuit part of the transformer, composed of silicon steel sheets and clamping devices;
Core: In the iron core of a three-phase transformer, the upright part is called the core column, on which the low-voltage winding and high-voltage winding of the transformer are sleeved; the horizontal part is called the yoke, which is used to form a closed magnetic circuit;
Winding: Also known as a coil, it is the main component for completing the transmission and conversion of electrical energy;
Oil tank: The outer shell of the transformer, in which the iron core and windings are installed;
Oil conservator: Commonly known as the oil pillow, connected to the transformer’s oil tank through a pipeline;
Bushing: The insulator between the guide rod and the tank cover, which plays the role of insulation and fixing the guide rod;
Breather;
Pressure relief device;
Thermometer;
Tap changer;
Oil purifier
