Low Noise Oil Immersed Type Transformer / Three Phase Transformer
We offer Oil Immersed Power and Distribution Transformers.
Distribution transformers for industrial application is available
with primary voltages of up to 33 KV and secondary voltages ranging
from 433 to 11000 V. The capacity range is up to 5000 KVA. We
manufacture single phase distribution transformers, three phase
distribution transformers and industrial distribution transformers.
These single phase distribution transformers and three phase
distribution transformers are available with ''Tap Changer''
options as well as "Off Circuit Manually Operated" and "On Load Tap
Changer" (OLTC) with AVR and RTCC panel.
Copper foil winding technology is used for high current sections to
achieve following advantages:
Sustaining short circuit forces without any distortion in low
voltage and high current winding
Hot spot in LV windings regulated
No transposition, stray losses are minimal. Thus total copper
losses are also further reduced
Total copper losses reduced vis-a-vis standard losses. Thus heat
dissipating area also reduce
Oil Immersed Type Transformer Description
A power transformer is a static electrical device that is used to
convert a certain value of an alternating voltage (current) into
another voltage or current of a different value (current). Widely
used in lighting, machine tools, mechanical and electronic
equipment, medical equipment, rectifiers, military, aerospace and
so on. Product performance can meet the special requirements of
Oil Immersed Type Transformer classification
Transformers can be divided into power transformers, test
transformers, instrument transformers and special transformers for
Power transformers are necessary equipment for power transmission
and distribution and power user distribution;
Test equipment for carrying out pressure (boost) tests on
The instrument transformer is used for electrical measurement and
relay protection of the power distribution system (PT, CT);
Main components of Oil Immersed Type Transformer
Moisture absorber (silicone tube)
Oil level gauge
Gas signal relay (gas relay)
Oil Immersed Type Transformer maintenance
The outdoor oil-immersed transformer shall be tested for insulating
oil once a year, and the indoor oil-immersed transformer shall be
tested for insulating oil once every two years.
Check the temperature and sound of the transformer for normality,
and whether there are odors, discoloration, overheating and smoke.
Keep the surface of the porcelain bottle, casing and magnetic
surface clean and observe whether there is crack damage or
The oil level of the oil-immersed transformer should be in
accordance with the standard, the color is normal, and there is no
Whether the junction of the transformer high, low voltage and
grounding is in good contact and there is no discoloration.
