Our company offers power & distribution transformers, which are designed and manufactured according to our standard specification or customer's specifications. Power distribution transformers have aluminum / copper wound, high grade non aging CRGO core, oil filled, ONAN air cooled transformers.

• 50/60 Hz, 11/0.250 KV single phase 10, 16 and 25 KVA capacities
  
• 50/60 Hz, 11/0.433 KV three phase 10 to 1000 KVA capacities
  

Power transformers, 50 / 60 Hz, 33 / 11 KV oil filled ONAN cooling having voltage variation from (+)5 % to (-)5 % in step of 2.5%. and (+)3% to (-)9% in step of 3% on HV side through manually operated off load tap changer.

Available in 1.5, 3, 3.15, 5, 6.3, 7.15 and 8 MVA capacities

Power transformer, 50 / 60 Hz, 33 / 11 KV oil filled ONAN cooling having voltage variation from (+)5% to (-)15 % on HV side through remote controlled on load tap changer (OLTC) in the steps of 1.25%.

Available in 5, 6.3, 7.15, 8, 10, 12, 15 and 20 MVA capacities. 

Power transformers 50 / 60 Hz, 33 / 0.433 KV oil filled ONAN cooling having voltage variation from (+)5% to (-)7.5% on HV side through off load tap changer in step of 2.5%.

Available in 25 KVA to 5 MVA capacities

We manufacture single phase, 50 Hz, oil immersed, naturally cooled, pole mounted / platform mounted, double wound with aluminum / copper, step up / step down core type continuous duty transformers having no load voltage ratio from 5 KVA to 167 KVA upto 33 KV.

We manufacture three phase liquid filled transformers can be supplied with cooling either by corrugations on the side of the tank or pressed steel radiators mounted on tank body. Transformers can be filled with either oil or one of several low flammability synthetic fluids such as midel. Both types can be supplied with HV and LV Switchgear incorporated into substations.

Specifications:

• Rated Primary Voltage : 33KV
• Secondary Voltage : 11KV
• ONAN Cooled, Outdoor type, Oil immersed Copper Wound, Open Type with Conservator
• Capacity kVA : 3150

Efficiency at 100% load (%):

P.F. -> 1	P.F. -> 0.8
99.02	98.75

We put forth a range of constant voltage transformers that are highly efficient. In these constant voltage transformers, there are no semi conductors or moving parts that makes them highly reliable. These constant voltage transformers have short term over load capability and higher input voltage control range for loads less than rated load. Precision made, these constant voltage transformers come with very high line rejections capability and excellent input to output isolation characteristics.
