Features of Products:

The series of dry-type transformers is used to directly reduce 35kV power supply to 400V distribution power supply for users and reduce 10kV transmission and transformation links. It significantly reduces operating costs, reduces multi-level substation engineering construction and have significant social benefits. By optimizing the structure of the high-voltage coil, the product improves the distribution of voltage and capacitance between layers, greatly improves the impact resistance of the product against atmospheric overvoltage and also improves the electric field distribution, which further reduces the volume of product.
