Product Introduction

The 2000 kVA Oil type distribution transformer was delivered to Ethiopia in 2021.

The rated power of the transformer is 2000 kVA with ONAN cooling, the primary voltage is 33kV with ±2*2.5% tapping range (NLTC), the secondary voltage is 0.4kV, they formed a vector group of Dyn5.

Our 2000 KVA distribution transformer was designed with advanced technology and adopts high quality material and components which result in reliable quality and long operation time.

We ensure that each one of our delivered units has undergone rigorous full acceptance testing. We provide one-package service from consulting, quoting, manufacturing, installation, commissioning, training to after sale services, our products are now operating in more than 50 counties in the world. We aim to be your most reliable supplier as well as your best partner in business!

2000 kVA-33/0.4kV Transformer Manufacturing Process

Transformer Construction of the Core:

Winding:

1.Our windings are made of high quality copper.

2.Both High Voltage (HV) and Low Voltage (LV) windings are done using Coil Winding Machines. The Copper strips/wires used in winding are meticulously selected for its quality to give the best output. The Copper strips/wires are paper covered and acts as insulators.

2000 kVA-33/0.4kV Transformer Oil Tank

Oil Tank:

1. The oil tank is a transformer housing containing the iron core, winding and transformer oil.

2. The corrugated tank structure is fully sealed, and the corrugated will expand and compress with the increase of oil, isolating the transformer from the atmosphere and preventing oil deterioration and moisture. After oil removal, rust removal and phosphating treatment, the surface of corrugated oil tank is coated with rainproof paint. Moisture and salt spray.

2000 kVA-33/0.4kV Transformer Testing

Routine tests of transformer include:

1.Winding resistance test of transformer

2.Transformer ratio test

3.Transformer vector group test

4.Measurement of impedance voltage/short circuit impedance (principal tap) and load loss (Short circuit test)

5.Measurement of no-load loss and current (Open circuit test)

6.Measurement of insulation resistance

7.Dielectric tests of transformer.

8.Tests on on-load tap-changer.

9.Oil pressure test on transformer to check against leakages past joints and gaskets

Packing and Delivery

FAQ

1. Where is your main market?

We had exported our transformers to more than 50 countries in the world, our main market is Africa countries, South and North American countries, and Asia countries.

2. What certificate do you have?

We have KEMA, CESI, CTQC type test report for our transformers.

3. How long is your delivery time?

30 days after drawing confirmed by buyer for distribution transformers below 5000kva, bigger transformers depend on the capacity and components, normally 30-90days (with imported components)
