Product Introduction

This 300 KVA transformer was delivered to Chad in 2019. the rated power of the transformer is 300 KVA. It is a Step-down transformer 11KV to 0.415KV, the primary voltage is 11kv, the secondary voltage is 415v. It is a hermetically sealed transformer without conservator. This transformer can effectively prevent oil deterioration and insulation aging and enhance operation reliability. Our 300 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.

300 KVA 11/0.415KV Transformer Tap Changer

The function of tap changer

Ensure that the voltage of the power network changes within a reasonable range. The tap changer generally taps from the high-voltage winding. Because the high-voltage side current is small, the lead cross-sectional area and the contact surface of the tap switch can be reduced, reducing the volume of the tap switch.

Packing and Delivery

Notes for switching tap changer:

1. Power off the transformer before switching and take safety measures.

2. Three phases must be switched at the same time and in the same first gear.

3. Switch back and forth several times, and finally cut to the desired gear to prevent the contact effect from being affected by the oxidation film.

4. Three-phase DC resistance shall be measured after switching.

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)
