General

This transformer use for mining or chemical industry or other fields with high explosion-proof grade. power system is 3.3kV, 6kV, 10kV, 11kV, 12.5kV and 13.8kV .

Transformer have strong oil tank, there are high voltage Chambers and low voltage Chambers on both sides of the oil cover.

The transformer NOMEX insulation paper and high quality transformer oil, high quality CRGO core, primary and secondary use pure electrolytic copper, both winding and core have shielding processing.
