66/11KV Transformer Manufacturing Process Transformer Construction of the Core:
Transformer windings:
Windings are key components of the transformer, they are made of high-quality oxygen free copper, with our advanced technology and experience, our windings have the following features:
1. The windings are able to withstand lighting overvoltage, transient overvoltage, longtime overvoltage.
2. High heat resistant strength, it’s able to continuous working over 20 years under the heat generate by current.
3. The windings are able to withstand the short-circuit current.
4. High mechanical strength.
Transformer Oil Tank
Final Assembly：
The wound coils are placed carefully in the assembled core. Insulations are given wherever required using materials like press board. The CORE bolt and tie rods are fixed in position. The Primary and Secondary windings are connected as per the requirement.
