Product Introduction

This 750 KVA distribution transformer was delivered to Mozambique in 2017, the rated power of the transformer is 750 KVA. This 750 KVA Step Down transformer 11kv to 0.4kv, the primary voltage is 11kv, the secondary voltage is 400v. This oil cooled transformer used mineral oil, which has good insulation, good heat dissipation and so on. Our 750 KVA power 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.

750 KVA 11/0.4KV Transformer Tap Changer

Two types of tap changer for transformer：

There are two ways of transformer voltage regulation: no load voltage regulation and on load voltage regulation. It is called no-load voltage regulation if the tap voltage can be adjusted after power failure; it is called on load voltage regulation if the tap voltage can be adjusted on line.

Finished 750 KVA 11/0.4KV Transformer

Basic technical requirements for installation of transformer:

1. The transformer's high-voltage down lead and high-voltage bus must adopt copper core or aluminum core rubber insulated wire; 2. The different phase to phase distance of high-voltage bus, high-voltage down lead and drop out fuse must be less than 300 mm;

3. The distance between the low-voltage side line and the high-voltage down lead shall not be less than 150 mm;

4. It is strictly prohibited that the low-voltage line passes through the high-voltage down lead, and the sag of the lead up and down lead should be neat and consistent; 5. The transformer shell, circuit breaker, arrester ground wire and transformer low-voltage side zero line should be grounded together first;

6. The transformer platform should be kept horizontal and the height difference of diagonal line of the table should be less than 30mm.

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)
