Product Introduction

This 4 MVA Transformer was delivered to South Africa in 2019. the rated power of the transformer is 4000 KVA. It is a Step-down transformer 33KV to 415V, the primary voltage is 33KV, the secondary voltage is 415V. We use copper as our winding material, Copper has the advantages of low resistivity and good ductility, can make the transformer transmit voltage better. Our 4 MVA 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.

4 MVA 33/0.415KV Transformer Manufacturing

Why coil is used in transformer?

The current through the coil magnetizes the iron, and the field of the magnetized material adds to the field produced by the wire. ... By providing a closed path for the magnetic field lines, this geometry minimizes the magnetic reluctance and produces the strongest magnetic field.

Packing and Delivery

Maintenance of transformer breather

1、Check whether the moisture absorber changes color. If it is pink, it means that the moisture absorber is affected by moisture and needs to be treated. If it does not change color for a long time, it may be that the sealing gasket of the moisture absorber has not been removed. 2. Check whether the oil level of the transformer in the moisture absorber is low and whether it is necessary to add oil or replace the transformer oil

3. Check whether the glass cover of moisture absorber is tightened

4. Clean the bottom cover of the moisture absorber regularly to prevent the blockage from affecting the normal breathing of the transformer

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)
