Product Description

Product Description

1. The transformer core is made of cold-rolled silicon steel sheets with high magnetic conductivity and low loss. The layers gap is small, and the joints of each layer are staggered, which greatly reduces the no-load loss and current and noise.

2. The structure of the transformer body is compact, which reduces the radial force during short circuit and has strong ability to resist sudden short circuit.

3.2000KVA transformer generally of open structure with oil conservator, or increase the expansion of corrugated sheet to replace the function of oil conservator.

4.The transformer is  fully sealed and free for maintenance to prolong usage life.
