9.Altiude is not exceeding 1000m,ambient temperature not exceeding 40OC. If it can't meet such conditions,we will modulate parameters in accordance with standard.

1. Oxygen-free copper lines of lower resistivity, which will become smoother and burr-free after series of additional surface treatment, so the load loss of our transformer is lower and the electric performance is better.
2. High-quality silicon-steel plates which are of lower unit loss, and the no-load of the transformers is lower.
3. High-quality wooden laminating insulation pieces, which won’t split or move even under the influence of short circuit.
4. Thoroughly filtrated transformer oil containing less water, gas and impurities, which makes our transformers work better.
5. High-quality rubber sealing material, which can prevent the transformers form aging or leakage.
