Product Introduction

These 150 KVA 3 phase transformers were delivered to Pakistan in 2019, the rated power of the transformer is 150 KVA. This 150 KVA Step Down transformer 11kv to 0.4kv, the primary voltage is 11kv, the secondary voltage is 0.4kv. We can supply both 150 KVA Step Up and Step-Down transformer, the cooling is ONAN. Our 150 KVA distribution transformer was designed with advanced technology and adopts high quality material and components which result in reliable quality and long operation time.

SCOTECH ensure each one of our delivered transformers had passed the full acceptance test and we remains 0 fault rate record for more than 10 years so far, oil immersed power transformer is designed in accordance with IEC, ANSI and other major international standards.

Scope of Supply

Product: Oil Immersed distribution Transformer

Rated Power: Up to 5000 KVA

Primary Voltage: Up to 35 KV

Technical Specification

200 KVA power transformer specification and data sheet

150 KVA 11/0.4KV Transformer Manufacturing

Core:

1.The core is made of high-permeable grain-orientated top quality cold-rolled silicon sheet

2.The silicon sheet fabrication adopts "no-upper yoke lapped' technology and all lapped joints of the silicon sheet are 45 full-miters.

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 or Aluminum strips/wires used in winding are meticulously selected for its quality to give the best output. The Copper or Aluminum strips/wires are paper covered and acts as insulators.

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.

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 30 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)
