 6.6kV - 125kVA Cast Resin Dry Type Transformer , Three Phases , Two Winding , Power Distribution​

Product characteristic:
1. It can be directly installed at the load center, which is free of maintenance and install conveniently, therefore it has low comprehensive running cost.
2. With high moisture resistance, it runs normally at the moisture and can be put into operation without being dried after outage, with low loss and local discharge capacity.
3. It has small noise, strong short circuit resistance and excellent environmental performance, and can run under severe environmental condition.
4. It is safe, fire-retardant, fireproof and environment-friendly.
